Also other options and accessories are available, see Chapter 10 for details. Introduction 1-3 Analyzer features The following sections describe the analyzer's features. Individual chapters following this chapter describe each block of controls in more detail. Front and Rear Panels Analyzer functions are activated from the front panel by using front panel hardkeys or softkeys. Measurement results are displayed on the LCD (which also displays the measurement conditions and the instrument status). The front panel has input, output, and control ports to connect to the test station and a oppy disk drive to store data and instrument status. The rear panel has input and output connectors to control the analyzer from an external controller or to control external devices from the analyzer. The rear panel also has a connector used to control a BASIC program, a connector for an external keyboard, and a parallel I/O port controlled by the program. For more information, see Chapter 2. ACTIVE CHANNEL Block ENTRY Block The analyzer has two channels for independent measurement of parameters and display of data. This block has two keys that select the active channel. Once an active channel is selected, you can control it using the front panel keys and display its trace and data annotations. If you want to use the other channel, you must select the new channel before you make any other changes. For more information, see Chapter 3. This block provides the numerical and units keypad, the knob, and the step keys. These controls are used in combination with other keys to enter or change numeric data. For more information, see Chapter 4. MEASUREMENT Block This block controls the measurement and display functions. Each key provides access to softkey menus. Because the measurement functions are di erent for impedance, permittivity ", and permeability measurements, the menus accessed from the 4Meas5 and 4Cal5 keys are di erent for each measurement of operation. 4Meas5 Provides access to a series of menus used to select the parameters to be measured. This menu is also used to select xtures to be used for material (" and ) measurements. 4Format5 Displays the menu used to select the display format of the data. Various rectangular and polar formats are available 1-4 Introduction for display of measurement parameters selected by 4Meas5 key. 4Display5 Provides access to a series of menus used for instrument state and active channel display functions. These menus include dual channel display (overlaid or split), de nitions of the displayed active channel trace in terms of the mathematical relationship between data and trace memory, display intensity, color selection, active channel display title, frequency blanking, and equivalent circuit function. 4Scale Ref5 Displays the menu used to modify the axis scales and the reference line value. 4Bw/Avg5 Provides access to two di erent noise reduction techniques: sweep-to-sweep averaging, and on-point averaging. 4Cal5 Provides access to a series of menus that implement the calibration and xture compensation procedures. For more information, see Chapter 5. STIMULUS Block This block de nes the sweep range, and controls the trigger function, test signal and DC bias source. 4Sweep5 Provides access to a series of menus used for selecting the sweep type, editing the list sweep table, specifying the number of points to be displayed, and specifying the delay time. 4Source5 Displays the menu used to control the test signal, and DC bias. 4Trigger5 Provides access to a series of menus used for selecting trigger mode and trigger source. 4Start5, 4Stop5, 4Center5, and 4Span5 Used to specify frequency or power range of the stimulus. For more information, see Chapter 6. MARKER Block This block displays the marker on the screen and controls the marker function. Displays the marker and provides access to a series of 4Marker5 menus used for selecting the marker mode and displaying the sub-markers and the 1marker. 4Marker!5 Provides access to a series of menus used for changing selected measurement parameters to the current maker value. 4Search5 Displays menus used for searching the trace for a speci c amplitude related point and placing the marker on that point. 4Utility5 Displays a menu used for listing all marker values, calculating and displaying statistical values of the display trace, indicating the time elapsed since the sweep started, monitoring OSC or dc bias level applied to a DUT. Introduction 1-5 For more information, see Chapter 7. INSTRUMENT STATE Block This block provides control of channel-independent system functions. These include the controller modes, real-time clock, limit line and limit testing, HP Instrument BASIC, printing, saving instrument states and trace data to a built-in disk or memory. 4System5 Provides access to a series of menus used for programming HP Instrument BASIC, controlling the real-time clock and the beeper, de ning the limit line table, performing limit line testing, and change memory size for HP Instrument BASIC and the memory disk. 4Local5 Returns front panel control to the user from an external controller and displays a series of menus used to select the GPIB mode and modify the GPIB addresses. 4Preset5 Sets the analyzer to the preset state. See Appendix B, for a listing of the preset values. 4Copy5 Provides access to the menus used for controlling external printers and de ning the parameters. 4Save5 Provides access to the menus used for saving the instrument state and data to the oppy disk or memory disk. 4Recall5 Displays the menu used to recall the contents of disk les or memory disk back into the analyzer. For more information, see Chapter 8. 1-6 Introduction Front and Rear Panel, Test Station, and Test Heads 2 This chapter describes the features of the analyzer, the test station, and the test heads. It provides illustrations and descriptions of the analyzer's front panel features, the LCD and its labels, and the rear panel features and connectors. It also includes illustrations and descriptions of the Test station and test heads. Front Panel Analyzer functions are activated from the front panel (Figure 2-1) by using the front panel hardkeys or softkeys. In this manual, all front panel hardkeys and softkey labels are shown as 4Hardkey5 and Softkey , respectively. NNNNNNNNNNNNNNNNNNNNNNN Figure 2-1. Analyzer Front Panel Front and Rear Panel, Test Station, and Test Heads 2-1 1. Front Panel Keys and Softkeys Some of the front panel keys change instrument functions directly, and others provide access to additional functions available in softkey menus. Softkey menus are lists of up to eight related functions that can be displayed in the softkey label area at the right-hand side of the display. The eight keys to the right of the LCD are the softkeys. Pressing one of the softkeys selects the adjacent menu function. This either executes the labeled function and makes it the active function, causes instrument status information to be displayed, or presents another softkey menu. Some of the analyzer's menus are accessed directly from front panel keys and some from other menus. For example, the sweep menu accessed by pressing the 4Sweep5 key presents all the sweep functions such as sweep type, number of points, and sweep time. Pressing NUMBER of POINTS allows the required number of points displayed per sweep to be entered directly from the number pad. RETURN softkeys return to previous menus. DONE indicates completion of a speci c procedure and then returns to an earlier menu. Usually, when a menu changes, the present active function is cleared.

Requirements for the input signals to the rear panel connectors are provided in Chapter 12. Figure 2-3. Analyzer Rear Panel 1. External Reference Input Connects an external frequency reference signal to the analyzer that is used to phase lock the analyzer for increased frequency accuracy. When the analyzer is equipped with the external oven (option 1D5), this connector must be connected to REF OVEN connector. The external frequency reference function is automatically enabled when a signal is connected to this input. When the signal is removed, the analyzer automatically switches back to its internal frequency reference. Front and Rear Panel, Test Station, and Test Heads 2-9 2. Internal Reference Output Connects to the frequency reference input of an external instrument to phase lock it to the analyzer. 3. External Program RUN/CONT Input Externally triggers run or cont of the HP Instrument BASIC program. The positive edge of a pulse more than 20 s wide in the low state triggers run or cont. The signal is TTL-compatible. 4. I/O Port Connects to external devices such as a handler on a production line. For more information on I/O port, see \I/O Port". 5. Power This is input for the main power cable. Insert the main-power cable plug only into a socket outlet that has a protective ground contact. 6 GPIB Interface Connects the analyzer to an external controller and other instruments in an automated system. This connector is also used when the analyzer itself is the controller of compatible peripherals. See \GPIB" in Chapter 8. 7. mini-DIN Keyboard Connector Connects the keyboard that is usually used with HP Instrument BASIC. 8. External Trigger Input Triggers a measurement sweep. The positive (or negative) edge of a pulse more than 20 s wide in the low (or high) state starts a measurement. The signal is TTL-compatible. To use this connector, set the trigger mode to external using softkey functions (see \4Trigger5" in Chapter 6). 9. Reference Oven Output (Option 1D5 Only) Connects to the EXT REF INPUT connector when option 1D5 is installed. Option 1D5 improves the frequency accuracy and stability of the analyzer. 10. Video Port This terminal outputs measurement results to an external color monitor. Color monitors supporting VGA (scan speed of 31.5 kHz) can be connected to this terminal. 11. Printer Port This interface enables the output of displayed results to a printer. It complies with the Centronics parallel interface standard. See \Printer" in Chapter 10 for supported printers. 2-10 Front and Rear Panel, Test Station, and Test Heads I/O Port Figure 2-4 shows the pin assignment of I/O port on the rear panel. Figure 2-4. Pin Assignment of I/O Port The signals carried through each pin are described below. OUT 0 thru 7 Output signals to external devices. Controlled by GPIB commands and HP Instrument BASIC statements and functions, as described below. Once SYST:COMM:PAR:TRAN:DATA is executed, the signal is latched until this command is executed again or power off. IN 0 thru 4 Input signals from external devices. Read by the GPIB command SYST:COMM:PAR:DATA?, as described below. Related GPIB Commands There are two GPIB commands that directly control an I/O port. SYST:COMM:PAR:TRAN:DATA This command outputs 8-bit data to the OUT 0 thru 7 lines. The OUT 0 signal is the LSB (least signi cant bit). The OUT 7 signal is the MSB (most signi cant bit). SYST:COMM:PAR:DATA? This command inputs data from the 4-bit parallel input port to the analyzer, and outputs the data to the controller. Related HP Instrument BASIC Statement and Function HP Instrument BASIC can access an I/O port directly by using the following statement and function. WRITEIO 15,0;A This statement outputs decimal value, A, as 8-bit data to the OUT 0 thru 7 lines. The OUT 0 signal is the LSB (least signi cant bit). The OUT 7 signal is the MSB (most signi cant bit). READIO(15,0) Front and Rear Panel, Test Station, and Test Heads 2-11 This function inputs data from the 4-bit parallel input port to the analyzer, and returns the data to the HP Instrument BASIC program.

High Impedance Measurement Test Head This test head is designed to measure high impedance with better accuracy. As a guide, when the impedance value of a DUT is grater than about 300 , use the high impedance measurement test head. This test head is furnished with 4291B. This test head is also used with the 16453A Dielectric Material Test Fixture. The impedance measurement accuracy using this test set is shown in the Chapter 12 (bound with this manual). Front and Rear Panel, Test Station, and Test Heads 2-15 Low Impedance Measurement Test Head (Option 012 only) This test head is designed to measure low impedance with better accuracy. As a guide, when the impedance value of a DUT is less than about 5 , use the low impedance measurement test head. This test head is furnished with Option 012. This test head is also used with the 16454A Magnetic Material Test Fixture. The impedance measurement accuracy using this test set is shown in the Chapter 12 (bound with this manual). When impedance of a DUT is almost in the range from 5 test heads can be used. to 300 , either or both High Temperature High Impedance Test Head (Option 013 only) This test head is designed to measure high impedance components or materials in wide temperature range. The analyzer can measure components or materials in temperature range from 055 C through +200 C, when this test head is used with the 16194A High temperature component xture or the 16453A Dielectric Material Test Fixture. This test head is furnished with Option 013. The dimensions of this test head and the impedance measurement accuracy using this test set is shown in the Chapter 12 (bound with this manual). High Temperature Low Impedance Test Head (Option 014 only) This test head is designed to measure low impedance component or material in high temperature condition. The analyzer can measure components or materials in temperature range from 055 C through +200 C, when this test head is used with the 16194A High temperature component xture or the 16454A Magnetic Material Test Fixture. This test head is furnished with Option 014. The dimensions of this test head and the impedance measurement accuracy using this test set is shown in the Chapter 12 (bound with this manual). 2-16 Front and Rear Panel, Test Station, and Test Heads Handling and Storage APC-7 R Connectors Keep connectors clean. Do not touch the mating plane surfaces. Do not set connectors contact-end down. Before storing, extend the sleeve. Use end caps over the mating plane surfaces. Never store connectors loose in a box or a drawer. Microwave connectors must be handled carefully, inspected before use, and when not in use stored in a way that gives them maximum protection. Avoid touching the connector mating plane surfaces and avoid setting the connector's contact-end down on any hard surface. Natural skin oils and microscopic particles of dirt are easily transferred to the connector interface and are very dicult to remove. Damage to the plating and to the mating plane surface occurs readily when the interface comes in contact with any hard surface. Never store connectors with the contact end exposed. End caps are provided with all Agilent Technologies connectors, and these should be retained after unpacking and placed over the ends of the connectors whenever they are not in use. Above all, never store any devices loose in a box or in a desk or a bench drawer. Careless handling of this kind is the most common cause of connector damage during storage. Calibration devices and test xtures should be stored in a foam-lined storage case, and protective end caps should always be placed over the ends of all connectors. Cables should be stored in the same shape as they have when they are used - they should not be straightened - and end caps should be placed over both connectors. The following gure summarizes these Agilent Technologies recommendations on handling and storing devices that have microwave connectors. Handle and Store Connectors Carefully Never Place Connectors Contact-End Down Use End Caps Extend threads fully when end caps are not used Use foam-lined storage cases if available Never store devices loose in a box or in a desk or bench drawer Front and Rear Panel, Test Station, and Test Heads 2-17 3 Active Channel Block The analyzer has two active channels (Figure 3-1) that provide independent display of data. Two di erent sets of data can be measured simultaneously (for example, one measurement with two di erent frequency spans). The data can be displayed separately or simultaneously. Figure 3-1. Active Channel Keys Active Channel Block 3-1 4Chan 15 and 4Chan 25 The 4Chan 15 and 4Chan 25 keys select which channel is the active channel. Active Channel This is the channel currently controlled by the front panel keys. The active channel trace and data annotations are displayed on the display. All the channel speci c functions that are selected apply to the active channel. The current active channel is indicated by an amber LED adjacent to the corresponding channel key. The analyzer has dual trace capability, so that both the active and inactive channel traces can be displayed, either overlaid or on separate graticules (split display). The dual channel and split display features are available in the display menus. Coupling Channels Stimulus Coupling The stimulus values can be coupled or uncoupled between the two channels (independent of the dual channel and split display functions). See \Sweep Menu" in Chapter 6 for a listing of the stimulus value that are coupled in the channel couple mode. Marker Coupling Another coupling capability is coupled markers. The measurement markers can have the same stimulus values for the two channels or they can be uncoupled for independent control in each channel. See Chapter 7 for more information about markers. 3-2 Active Channel Block 4 Entry Block The ENTRY block (Figure 4-1) contains the numeric and unit's keypad, the knob, and the step keys. These controls are used in combination with other front panel keys and softkeys to modify the active entry, to enter or change numeric data, and to change the value of the marker. In most cases, the keypad, knob, and step keys can be used interchangeably. Before a function can be modi ed, it must be made the active function by pressing a front panel key or softkey. It can then be modi ed directly with the knob, the step keys, or the digits' keys and a terminator. Figure 4-1. Entry Block Entry Block 4-1 Numeric Keypad The numeric keypad selects digits, decimal point, and minus sign for numerical entries. A unit's terminator is required to complete the entry. Terminator Keys The unit's terminator keys are the four keys in the right-hand column of the keypad. These specify units of numerical entries from the keypad and also terminate the entries. A numerical entry is incomplete until a terminator is entered. When a terminator is required, the data entry arrow \ " points at the last entered digit in the active entry area. When the unit's terminator key is pressed, the arrow is replaced by the units selected. The units are abbreviated on the terminator keys as follows: 4G/n5 4M/5 4k/m5 4x15 Knob * 4 5 and 4+5 4-2 Entry Block Giga/nano (109 / 1009 ) Mega/micro (106 / 1006 ) kilo/milli (103 / 1003 ) basic units: dB, dBm, degrees, seconds, Hz, V, A, F, H, , or S. (may be used to terminate unitless entries such as averaging factor). The knob adjusts the current values continuously for functions such as scale, reference level, and others. If a marker is on, and no other function is active, the knob can adjust the marker position. Values changed by the knob are e ective immediately and require no terminator. The 4+5 and 4*5 keys step the current value of the active function up or down. The steps are predetermined and cannot be altered. No unit's terminator is required with these two keys. 4Entry O 5 Clears and turns o the active entry area and any displayed prompts, error messages, or warnings. Use 4Entry O 5 to clear the display before plotting. This key also prevents active values from being changed by accidentally moving the knob. The next function selected turns the active entry area back on. 4Back Space5 Deletes the last entry (or the last digit entered from the numeric keypad). Entry Block 4-3 5 Measurement Block The measurement block keys and associated menus provide control of measurement parameter, display, equivalent circuit analysis, averaging, calibration, and xture compensation.

Scale Reference Menu NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNN AUTO SCALE Brings the trace data (de ned by the SCALE FOR key) in view on the display with one keystroke. Sweep values are not a ected, only scale and reference values. The analyzer determines the smallest possible scale factor that will put all displayed data onto the vertical graticule. SCALE/DIV Changes the response value scale per division of the displayed trace. In Smith, polar, and admittance chart formats, this refers to the full scale value at the outer circumference and is identical to the reference value. REFERENCE POSITION Sets the position of the reference line on the graticule of a Cartesian display (with 0 at the bottom line of the graticule and 10 at the top line). It has no e ect on a Smith, polar or admittance chart format. The reference position is indicated with a small triangle just outside the graticule, on the left. REFERENCE VALUE Changes the value of the reference line, moving the measurement trace correspondingly. In Smith, polar and admittance chart formats, the reference value is the same as the scale and is the value of the outer circle. MARKER!REFERENCE Makes the reference value equal to the marker's absolute value (regardless of the delta marker value). The marker is e ectively moved to the reference line position.

Averaging Menu NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN SWEEP AVG RESTART Resets the sweep-to-sweep averaging and on-point averaging, and restarts the sweep count at 1 at the beginning of the next sweep. The sweep count for averaging is displayed at the left of the display. SWEEP AVG ON off Turns the sweep-to-sweep averaging function on or off for the active channel. When averaging is on,\Avg" is displayed in the status notations area at the left of the display (along with the sweep count for the averaging factor). Whenever an instrument state change a ecting the measured data is made, the sweep count for averaging is reset to 1. NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN At the start of averaging or following AVERAGING RESTART , averaging starts at 1 and averages each new sweep into the trace until it equals the speci ed averaging factor. The sweep count is displayed in the status notation area below \Avg" and updated each sweep as it increments. When the speci ed averaging factor is reached, the trace data continues to be updated, weighted by that averaging factor. SWEEP AVG FACTOR Makes the sweep-to-sweep averaging factor the active function. Any value up to 999 can be used. POINT AVG on OFF Turns the on-point averaging function on or off for the active channel. POINT AVG FACTOR Makes the point averaging factor the active function. Any value up to 999 can be used. NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN 5-52 Measurement Block 4Bw/Avg5 Averaging On Sweep and Averaging On Points Averaging On Sweep Averaging-on-sweep computes each data point based on an exponential average of consecutive sweeps weighted by a user-speci ed averaging factor. Each new sweep is averaged into the trace until the total number of sweeps is equal to the averaging factor, for a fully averaged trace. Each point on the trace is the vector sum of the current trace data and the data from the previous sweep. A high averaging factor gives the best signal-to-noise ratio, but slows the trace update time. Doubling the averaging factor reduces the noise by 3 dB. The algorithm used for averaging-on-sweep is: A(n) = S(n) 1 + (1 0 ) 2 A(n01) F F Where, A(n) = current average S(n) = current measurement F = average factor Averaging On Points Averaging-on-points averages each data point by a user-speci ed averaging factor. The analyzer repeats measuring the same point until the averaging factor is reached. It then divides the vector summation of measurement value by the averaging factor and starts measuring the next point. The sweep time increases in proportion to the averaging factor. The algorithm used for averaging-on-points is: M= F 1 X F S(n) n=1 Where, M = Measurement Result S(n) = current measurement F = average factor Measurement Block 5-53 4Cal5 4Cal5 Figure 5-41.

Sweep Menu NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN SWEEP TIME [ ] Makes sweep time the active function and leads to the following softkeys, which are used to specify sweep time and set automatic sweep time. SWEEP TIME AUTO Selects the optimum (fastest) sweep time automatically. Pressing this softkey sets the point delay time to zero. :h:m:s Makes manual time entry the active function. Enters \:" automatically. POINT DELAY TIME Makes point delay time the active function. When the point delay time is set, the analyzer delays the start of the measurement for the delay time speci ed at each measurement point. (See Figure 6-4.) SWEEP DELAY TIME Makes sweep delay time the active function. When the sweep delay time is set, the analyzer delays the start of the sweep for the delay time speci ed at each sweep. (See Figure 6-4.) NUMBER of POINTS Sets the number of data points per sweep. Using fewer points allows a faster sweep time but the displayed trace shows less horizontal detail. Using more points gives greater data density and improved trace resolution, but slows the sweep. In list frequency sweep, the number of points displayed is the total number of frequency points for the de ned list. COUPLED CH ON off Toggles channel coupling of the stimulus values. With COUPLED CH ON (the preset condition), both channels have the same stimulus values (the inactive channel takes on the stimulus values of the active channel). For information on the parameters that are coupled or uncoupled by the coupling function, see the table after Figure 6-4.

LIST Selects list frequency sweep. If a list is not de ned, this softkey performs no function. SWEEP DIR [ ] Toggles direction of sweep between up and down. When DOWN is selected, the analyzer sweep starts from the stimulus STOP value and sweeps to the START value. DOWN is only available for the OSC level, dc voltage, and dc current sweep. The down sweep is not available for frequency sweep. LIST MENU Leads to the List menu, which is used to control the list sweep and de ne the list sweep table. Figure 6-4 shows the relationship between delay time and sweep time. The sweep delay time is not included in the sweep time. The summation of all point delay times is added to the sweep time.

List Menu NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN LIST DISP:FREQ BASE Displays data measured as frequency base in the frequency list mode. The frequency scale is linear across the total range. Because the frequency points may not distribute evenly across the graticule, the display resolution may be uneven. This causes the points to be more compressed in some parts of the trace than in other parts. ORDER BASE Displays data measured as order base in the frequency list mode. The displayed frequency resolution is even across the graticule, even though the frequency points are not distributed evenly. For more information, see the explanation of \Frequency Base and Order Base" on the next page. EDIT LIST Leads to the following softkeys, which are used to de ne or modify the frequency sweep list: SEGMENT Determines a segment on the list to be modi ed. Enter the number of a segment in the list, or use the step keys to scroll the pointer \>" at the left to the required segment number. The indicated segment can then be edited or deleted. EDIT Provides the Segment menu, which is used to de ne or modify the segment selected using SEGMENT . The segment indicated by the pointer \>" at the left can be modi ed. DELETE Deletes the segment indicated by the pointer \>" at the left. ADD Adds a new segment to be de ned with the Segment menu. If the list is empty, a default segment is added and the Segment menu is displayed so it can be modi ed.

NNNNNNNNNNNNNNNNNNNNNNNNNNNNN The stimulus range of a segment can not be overlapped with other segments. The analyzer always sweeps from a lower frequency to a higher frequency (independent of the de nition of the segments). Frequency Base and Order Base The result of a list sweep is displayed using one of the two display modes; frequency base display mode or order base display mode. Frequency base: The X-axis is linearly scaled by frequency. The analyzer automatically scales linearly from the sweep list. When the stimulus range of a segment is discontinuous from another segment, the segment traces are connected by a straight line. Order base: The X-axis is linearly scaled by the number of sweep points according to the sweep list. The following gures show an example of the di erence between these modes. This measurement has two segments, one is resonance frequency and another is anti-resonance frequency. The span of the lower segment is narrower than the span of the higher segment. If the trace of this list is displayed on the frequency base scale, the sweep points of interest cannot be displayed visibly (as shown in the left graph below). The order base can display this trace as shown in the right graph. Frequency Base 6-8 Stimulus Block Order Base 4Sweep5 Segment Menu Figure 6-6.

In other words, you cannot turn on or o the dc bias of either channel 1 or 2. The dc bias is automatically turned o when the calibration or xture compensation measurement is done. Marker Level Monitor Function The analyzer can monitor the OSC level output and dc bias level applied to the DUT at each stimulus point using the marker. The softkey for the marker level monitor can be accessed from the 4Utility5 key in the MARKER block. See \4Utility5" in Chapter 7. Source level value entered is not equal to the value applied to the DUT For example, the OSC level voltage value displayed (or entered) is twice the value when terminating with 50 . (In other words, the OSC level displayed is approximately equal to the value when the terminal is open.) When the DUT is connected to the test terminal, the voltage dropped by the DUT's impedance causes the voltage value applied the DUT to be less than the OSC level setting. Vosc = 2 2V50 Vosc ' Vopen Vosc 6= Vx De nition of the OSC Level The de nitions of the OSC level are as follows: OSC voltage level (Vosc ) : Vosc is twice as large as the voltage value when terminating with 50 (approximately same as open voltage). OSC current level (Iosc ) : Iosc is twice as large as the current value when terminating with 50 (approximately same as short current). OSC power level (Posc ) : Posc is as the same as the power level when terminating with 50 Voltage Level Vosc = 22V50 Current Level Iosc = 22I50 Power Level Posc =P50 Stimulus Block 6-11 4Trigger5 4Trigger5 Figure 6-8.

The rst is the active marker (or the marker) that is displayed on the screen (as 5) when 4Marker5, 4Maker!5, 4Search5, or 4Utility5 is pressed. When a marker is turned on and no other function is active, the marker can be controlled with the knob, or the step keys. The second is the sub-markers that appear at the present marker position when a softkey in the sub-marker menu is pressed. The seven sub-markers can be displayed for each channel at the same time (a total of 14). The third is the 1marker that de nes a reference position of the delta mode. There are three 1mode markers, 1marker (normal), tracking 1marker, and xed 1marker. Marker Value Markers have a stimulus value (the x-axis value in a Cartesian format) and a measurement value (the y-axis value in a Cartesian format). In a polar, Smith, admittance chart, or complex plane format, the second part of a complex data pair is also provided as an auxiliary measurement value. The marker can be moved to any point on the trace. Its measurement and stimulus values are displayed at the top right corner of the graticule for each displayed channel (in units appropriate to the display format). The displayed marker measurement values are valid even when the measured data is above or below the range displayed on the graticule. When marker list is turned on, stimulus values and measurement values of all markers are listed on the graticule. In a polar, Smith , or admittance chart format, auxiliary measurement values of all markers are also listed. X-axis Value to be Displayed Stimulus Value Normally, the marker displays the stimulus value at the current marker position for the x-axis value. Time When time is selected as the x-axis value to be displayed (instead of the marker value), the x-axis is changed to the time scale. The start point of the x-axis is 0 seconds and the stop point indicates the sweep time. Relaxation Time (1/2f) When marker relaxation time (1/2f) is selected as the x-axis value to be displayed (instead of the stimulus value), the x-axis is changed to the 1/2f scale. 7-20 Marker Block Marker Function Marker Level Monitor The analyzer has the capability to monitor the output voltage or current level of the OSC level or dc bias. When the level monitor is turned on, the level monitor value on a marker point is displayed on the screen. The monitor value displayed is calculated from the current stimulus setting and the impedance value measured. OSC level monitor value The voltage value of the OSC level applied to the DUT (Vdut ) and the current value of the OSC level owing through the DUT (Idut ) are calculated using the following equations: Vdut = Vosc 2 Zmeas + 50 1 Idut = Vosc 2 Zmeas + 50 Idut = Iosc 2 Zmeas + 50 or Where, Vosc Iosc Zmeas Zmeas 50 Voltage setting value of the OSC level Current setting value of the OSC level Current measurement impedance value of the DUT Continuous/Discrete Mode Marker values are normally continuous (that is, they are interpolated between measured points). Alternatively, they can be set to read only discrete measured points. Marker on the Data Trace or on the Memory Trace If both data and memory are displayed, you can select which marker values apply to the data trace or the memory trace. If data or memory is displayed (not both), the marker values apply to the trace displayed. In a data math display (data+memory, data0memory, or data/memory), the marker values apply to the trace resulting from the memory math function. 1Mode With the use of a delta marker, a delta marker mode is available that displays both the stimulus and measurement values of the marker relative to the reference. Any position on the trace or a xed point can be designated as the delta marker. The 1marker can be put on a current position of the marker. If the delta reference is the xed 1marker, both its stimulus value and its magnitude value (y-axis value) can be arbitrarily set anywhere in the display area (not necessarily on the trace). If the delta marker is the tracking 1marker, its stimulus value can be controlled and its measurement value is the value of the trace at that stimulus value. Marker Block 7-21 Marker Function Marker Search Function Markers can search for the trace maximum/minimum, any other point, peak maximum/minimum or peak-to-peak value of all or part of the trace. The marker and sub-markers can be used together to search for speci ed width cuto points and calculate the width and Q. Statistical analysis uses markers to provide a readout of the mean, standard deviation, and peak-to-peak values of all or part of the trace. When the format is polar, Smith, admittance chart, or complex plane format, the marker search function searches for the primary marker value (not the AUX value) of the point speci ed.

Q Measurement Examples There are two kinds of Q parameters Generally, two kinds of Q factors are used to characterize electric devices, the impedance parameter Q factor and the Q value of a coil or resonator. However, these Q factors are quite di erent. The de nitions of them are as follows: Q factor of Impedance Parameter This Q factor is ratio of the resistance and reactance (or conductance and suceptance): Q= X R Where, R is resistance, X is reactance. Q value of Width Parameter This Q factor is the ratio of the bandwidth and center frequency of the trace: Q= BW C EN T ER Where, BW is bandwidth, CENTER is center frequency. Marker Block 7-25 Marker Function Peak De nition The search function provides the de ne peak feature, which speci es the properties of the peaks searched for by the peak search function. The de ne peak feature also allows the peak search function to discriminate peaks from noise. Peak De nition The following parameters are used in the peak de nition: Peak polarity (positive or negative) 1X, 1Y (gradient) Threshold value The search functions search for a peak where the parameters of the peak match the following conditions: 11XY 2SP AN min(1yL , 1yR ) (NOP 01) and Threshold Peak Amplitude Value Where, 1yL and 1yR are the di erence in amplitude value between a peak and the adjacent measurement points on both sides. That is, the search functions search for a peak where, the gradient is greater than 1Y/1X, and the amplitude is greater than the threshold value. The search functions ignore a peak when the amplitude value is less than the threshold even if the peak polarity is set to negative. Figure 7-15.

When logging is on, the analyzer logs the equivalent GPIB commands of all front panel key inputs into the HP Instrument BASIC program. NNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN Logging Function When an Instrument BASIC program is running, waiting for an input, or being edited, logging cannot be turned on. When the analyzer does not have a program loaded, the following statements are automatically inserted at the beginning and the end of the program. ASSIGN @Hp4291 TO 800 END When there are already some statements in the Interment BASIC editor, the program lines logged are inserted at the current cursor line. The short form of the command is logged and the sux (unit of parameter) is omitted. If the command logged exceeds the memory capacity for the Instrument BASIC, error will occur. If you make an input error when logging is ON, the analyzer generates the equivalent codes faithfully and the resulting program is incorrect.

Instrument State Block 8-39 Limit Line Concept Limit Line Concept These are lines drawn on the display to represent upper and lower limits or device speci cations with which to compare the DUT. Limits are de ned by specifying several segments, where each segment is a portion of the stimulus span. Each limit segment has an upper and a lower starting limit value. Limits can be de ned independently for the two channels with up to 18 segments for each channel (a total of 36 for both channels). These can be in any combination of the two limit types. Limit testing compares the measured data with the de ned limits, and provides pass or fail information for each measured data point. An out-of-limit test condition is indicated in the following ways: Displaying a FAIL message on the screen. Emitting a beep. Displaying an asterisk in tabular listings of data. Writing a bit into bit 3 and 4 of the instrument status resister. Limits are entered in tabular form. Limit lines and limit testing can be either on or off while limits are de ned. As new limits are entered, the tabular columns on the display are updated, and the limit lines (if on) are modi ed to the new de nitions. The complete limit set can be o set in either stimulus or amplitude value. How Limit Lines are Entered Before limit lines can be explained, the concept of \segments" must be understood. A segment is the node of two limit lines. See Figure 8-26. Figure 8-26. The Concept of Segments as a Point between Two Sets of Limit Lines As you can see in Figure 8-26, segments are distinct points that de ne where limit lines begin or end. Limit lines span the distance between segments and represent the upper and lower test limits. Figure 8-26 shows another important aspect of limit lines. The far left hand side of a set of limit lines will continue from the minimum stimulus value 8-40 Instrument State Block Limit Line Concept (start) and the far right hand side of a set of limit lines will continue until the maximum stimulus value (stop). A segment is placed at a speci c stimulus value (a single frequency for example). The rst segment de nes the limit line value from the minimum stimulus value. Once its stimulus value is entered, the upper and lower test limit (5 k and 4.8 k for example) need to be supplied. De ning a second segment de nes where the rst set of limit lines ends. This process is repeated to create di erent sets of limit lines, each having new upper and lower limits. Up to 18 segments can be entered. Limits can be de ned independently for the two channels. The example in Figure 8-26 shows a combination of limit lines that change instantly and gradually. Segment 1 is at 200 MHz and has an upper and lower limit of 5 and 4.8 k , respectively. Notice the upper and lower limit lines start at the start frequency (100 MHz) and end at segment 1. Segment 2 is also at 200 MHz with di erent upper and lower limits of 5.1 k and 4.9 k , changing the limit values instantly. Segment 3 is at 300 MHz with the same limit value as segment 2 to obtain a at limit line. Segment 4 is at 400 MHz with upper and lower limit values of 5.2 k and 5 k , changing the limit values gradually. Notice the upper and lower limit lines start at the segment and continue until the stop frequency (500 MHz). Limit lines cannot be cut When limit lines are needed partially along the stimulus axis, the non-limit-testing portion must also be entered. Set the non-limit-testing portion by forcing the upper and lower limit values out of range (+1 G and 01 G for example). Both an upper limit and a lower limit (or delta limits) must be de ned. If only one limit is required for a particular measurement, force the other limit out of range (+1 G or 01 G for example). Turning Limit Lines and Limit Testing On and O Limit lines and limit testing features are off unless explicitly turned on by the user. After entering the limit line information, you can turn on the limit line feature and optionally the limit testing features. Turning these features off has no e ect on the entered limit line information. Instrument State Block 8-41 Limit Line Concept Segment Entering Order Generally, the segments do not have to be entered in any particular order. The analyzer automatically sorts them and lists them on the display in increasing order of stimulus value. One exception is when two segments have the same stimulus value as described in Figure 8-26. If the same stimulus values exist, the analyzer draws the limit lines according to entered segment order. For example, in Figure 8-26, segment 1 should be entered in advance of segment 2. Saving the Limit Line Table Limit line information is lost if the LINE switch is turned o . However, the 4Save5 and 4Recall5 keys can save limit line information along with all other current analyzer settings. Limit line table information can be saved on a disk. O setting the Stimulus or Amplitude of the Limit Lines All limit line entries can be o set in either stimulus or amplitude values. The o set a ects all segments simultaneously. Supported Display Formats Limit lines are displayed only in Cartesian format. In polar and Smith chart formats, limit testing of one value is available. The value tested depends on the marker mode and is the magnitude or the rst value in a complex pair. The message \NO LIMIT LINES DISPLAYED" is shown on the display in polar and Smith formats. Use a Sucient Number of Points or Errors May Occur Limits are checked only at the actual measured data points. If you do not select a sucient number of points, it is possible for a device to be out of speci cation without a limit test failure indication. To avoid this, be sure to specify a high enough number of points. In addition, if speci c stimulus points must be checked, use the list sweep features described in \4Sweep5" in Chapter 6 so that the actual measured data points are checked. Displaying or Printing Limit Test Data The \list values" feature in the copy menu prints or displays a table with each measured stimulus value. The table includes limit line and limit test information (if these functions are turned on). If limit testing is on, an asterisk \3" is listed next to any measured value that is out of limits. If the limit lines are on, and other listed data allows sucient space, the following information is also displayed: Upper limit and lower limit The margin by which the device passes or fails the nearest limit 8-42 Instrument State Block Limit Line Concept For more information about the list values feature, see \Copy Menu". Results of Printing the Display with Limit Lines ON If limit lines are on, they are shown when you print the display. If limit testing is on, the PASS or FAIL message is included as well. Note An example of a measurement using limit lines and limit testing is provided in the Quick Start Guide. A sample program performing a limit test using GPIB commands is provided in the Programming Manual . Instrument State Block 8-43 GPIB Function GPIB What is GPIB? The analyzer is factory-equipped with a remote programming digital interface using the GPIB. This allows the analyzer to be controlled by an external computer that sends commands or instructions to and receives data from the analyzer using the GPIB. In this way, a remote operator has the same control of the instrument available to a local operator from the front panel, except for the line power switch. In addition, the analyzer itself can use GPIB to directly control compatible peripherals, without the use of an external controller. It can output measurement results directly to a compatible printer or plotter. This section provides an overview of GPIB operation. The Quick Start Guide provides information on how to use the analyzer to control peripherals. It also explains how to use the analyzer as a controller to print and plot. More complete information on programming the analyzer remotely over GPIB is provided in Programming Manual. The Programming Manual includes examples of remote measurements using an HP Vectra PC with BASIC programming. The Programming Manual assumes familiarity with front panel operation of the instrument. For more information on the IEEE 488.1 and 488.2 standard, see IEEE Standard Digital Interface for Programmable Instrumentation, published by the Institute of Electrical and Electronics Engineers, Inc., 345 East 47th Street, New York 10017, USA. How GPIB Works The GPIB uses a party-line bus structure in which up to 15 devices can be connected on one contiguous bus. The interface consists of 16 signal lines and 6 grounded lines in a shielded cable. With this cabling system, many di erent types of devices including instruments, computers, plotters and printers can be connected in parallel. Every GPIB device must be capable of performing one or more of the following interface functions: Talker A talker is a device capable of sending device-dependent data when addressed to talk. There can be only one active talker at any given time. Examples of this type of device are voltmeters, counters, and tape readers. The analyzer is a talker when it sends trace data or marker information over the bus. Listener A listener is a device capable of receiving device-dependent data when addressed to listen. There can be any number of active listeners at any given time. Examples of this type of device are printers, power supplies, and signal generators. The analyzer is a listener when it is controlled over the bus by a computer. 8-44 Instrument State Block GPIB Function Controller A controller is a device capable of managing the operation of the bus and addressing talkers and listeners. There can be only one active controller at any time. Examples of controllers include desktop computers and minicomputers. In a multiple-controller system, active control can be passed between controllers, but there can only be one system controller that acts as the master, and can regain active control at any time. The analyzer is an active controller when it plots or prints in the addressable mode. The analyzer is a system controller when it is in the system controller mode. GPIB Requirements Number of Interconnected Devices 15 maximum Interconnection Path/Maximum Cable Length 20 meters maximum or 2 meters per device, whichever is less. Message Transfer Scheme Byte serial/bit parallel asynchronous data transfer using a 3-line handshake system. Data Rate Maximum of 1 megabyte per second over limited distances with tri-state drivers. Actual data rate depends on the transfer rate of the slowest device involved. Address Capability Primary addresses: 31 talk, 31 listen. A maximum of 1 active talker and 14 active listeners at one time. Multiple Controller Capability In systems with more than one controller, only one can be active at any given time. The active controller can pass control to another controller, but only one system controller is allowed. Analyzer GPIB Capabilities As de ned by the IEEE 488.1 standard, the analyzer has the following capabilities: SH1 Full source handshake. AH1 Full acceptor handshake. T6 Basic talker, answers serial poll, unadresses if MLA is issued. No TE0 L4 LE0 SR1 RL1 PP0 DC1 DT1 C1, C2, C3, C4 C11 E2 talk-only mode. Does not have extended address of talker. Basic listener, unadresses if MTA is issued. No listen-only mode. Does not have extended address of listener. Complete service request (SRQ) capabilities. Complete remote/local capability including local lockout. Does not respond to parallel poll. Complete device clear. Responds to a group execute trigger. System controller capabilities in system controller mode. Pass control capabilities in addressable mode. Tri-state drivers. Instrument State Block 8-45 GPIB Function Bus Mode The analyzer uses a single-bus architecture. The single bus allows both the analyzer and the host controller to have complete access to the peripherals in the system. Two di erent modes are possible, system controller and addressable. System Controller This mode allows the analyzer to control peripherals directly in a stand-alone environment (without an external controller). This mode can only be selected manually from the analyzer front panel. Use this mode for operation when no computer is connected to the analyzer. Addressable This is the traditional programming mode, in which the external computer is involved in all peripheral access operations. When the external controller is connected to the analyzer through GPIB (as shown in Figure 8-27), this mode allows the external controller to control the analyzer over GPIB in the talker mode in order to send data, and in the listener mode to receive commands. Programming information for the addressable mode is provided in the Programming Manual. Figure 8-27. Analyzer Bus Concept 8-46 Instrument State Block GPIB Function Setting Addresses In GPIB communications, each instrument on the bus is identi ed by an GPIB address. This address code must be di erent for each instrument on the bus. See Appendix B for information on default addresses, and on setting and changing addresses. These addresses are not a ected when you press 4Preset5 or cycle the power. Instrument State Block 8-47 Saving and Recalling Saving and Recalling Instrument States and Data Storage Devices The analyzer supports two storage devices, a oppy disk drive and a memory disk. The oppy disk drive is suited to storing large numbers of les and long term data storage. memory disk is suited to storing tentative data and instrument states and to store or get data quickly. Disk Requirements The analyzer's disk drive uses a 720 Kbyte or 1.44 Mbyte 3.5 inch oppy disk. See the \System accessories available" in Chapter 10 for disk part numbers. Disk Formats The analyzer's built-in disk drive can access both LIF (logical interchange format) and DOS formatted disks. The disk drive and the memory disk can also initialize a new disk in either LIF or DOS format. The following list shows the applicable DOS formats for the analyzer: 1.44 Mbyte, 80 tracks, double-sided, 18 sectors/track Memory disk Capacity The memory disk capacity is 448 Kbyte. This capacity includes the directory area. The capacity of data area depends on the disk format type. Copy Files Between the memory disk and the oppy Disk A copy function is provided to copy les between the memory disk and the oppy disk. FILE UTILITIES in the SAVE menu displays the softkeys used to copy les. The GPIB command MMEMory:COPY is also available to copy les (See the Programming Manual). When the format of the memory disk is di erent from the format of the oppy disk, the copy function and the command can not be used. NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN File Types and Data Groups File Types The analyzer supports two le types, binary and ASCII, that are used to save data on a disk. Binary File Binary les are used to save measurement conditions and data using the SAVE function and to retrieve binary data using the RECALL function. External controllers and Instrument BASIC can read measurement data from binary data les. ASCII le ASCII measurement data or screen image les can be read by commonly available IBM PC based software for data analysis or other secondary functions. The RECALL function cannot read ASCII les. 8-48 Instrument State Block Data Groups Saving and Recalling Instrument States and Internal Data Arrays (STATE) This group consists of the instrument states that include raw calibration coecients, the data arrays, and the memory arrays. (Binary Files Only) Internal Data Arrays (DATA ONLY) The internal data arrays that are stored in the analyzer's memory consist of the following six data arrays. See \Data Processing" in Chapter 9 for complete information on each data array and their relationships.(Binary and ASCII Files) Calibration Coecients arrays contain the expanded calibration coecients obtained by calibration and xture compensation. Raw data arrays contain the calibrated data obtained using the calibration coecients. Data arrays contain the compensated data obtained using the compensation coecients. Memory arrays contain the memory data arrays obtained using the DATA!MEM operation. Data-Trace arrays contain the formatted data. Memory Trace arrays contain the formatted data of the \memory arrays." These arrays can be saved selectively to suit the application. For example, when measuring several devices with the same measurement settings, you may need to save only the trace arrays for each device. Saving only the necessary arrays reduces the disk space required and the disk access time. In addition, saving internal data also allows the analysis of the measurement results using an external controller. See \File Structure of Internal Data Arrays File for Binary Files" for more information. Graphics Images (GRAPHICS) Graphics consist of the graphic images on the screen created using TIFF (Tagged Image File Format). File Type and Data Group Combinations You can select and save to a disk one of the following four combinations of the two le types and the four data groups. Binary File Instrument states and internal data arrays (STATE) Internal data arrays (DATA ONLY binary) Graphics image (GRAPHICS) ASCII File Internal data arrays (DATA ONLY ascii) Instrument State Block 8-49 Saving and Recalling File Names All data saved using the built-in disk drive and the memory disk has an identifying le name. A le name consists of the lower and upper case alphabet, numbers, and valid symbol characters. Up to 8 characters can be used for a le name. The following table shows the valid characters for LIF and DOS le names. Valid Characters for File Names Valid Characters for LIF Valid Characters for DOS Format A - Z (Upper case alphabet)1 a - z (Lower case alphabet)1 0 - 9 (Numeric characters) (under line) A - Z (Upper case alphabet)2 a - z (Lower case alphabet)2 0 - 9 (Numeric characters) $ & # % ' !

If the le is found, the analyzer automatically uses the le to retrieve its data. When both state and data les have been saved, the analyzer recalls only the state le. Saving and Recalling File Structure of Internal Data Arrays File for Binary Files When internal data arrays are saved as a binary le, the arrays' le consists of a le header at the top of the le and the data groups following the le header. File Header Every internal data array le begins with a le header. The following gure shows the header structure. Figure 8-28. File Header Structure Seven data switches de ne the data group that follows the le head. Each one-byte switch is either 1 or 0 (decimal value) if the applicable data group exists or not, respectively. The data group to be followed is in the same order of these switches. For example, when the data switches, RAW DATA and DATA-TRACE are 1 (on), while the others are off, only the RAW DATA and DATA-TRACE (in this order) groups will follow the header. Instrument State Block 8-51 Saving and Recalling Data Group The data le structure of each channel begins with a header and consists of the same structured data segments. The number of data segments depends on the data group type as follows: RAW DATA consists of a header and four data segments per channel as shown in the following gure. They will follow the le header in this order: DATA consists of a header and a data segment by a channel. DATA-TRACE consists of a header and a data segment by a channel. Figure 8-29. RAW, DATA, and DATA-TRACE Data Group Structure 8-52 Instrument State Block Saving and Recalling CAL consists of data segments by a channel as shown in Figure 8-30. The rst half of the segments are for channel 1 and the second half of the segments are for channel 2. The contents of each segment depend on the type of calibration performed. (See \4Cal5" in Chapter 5.) Figure 8-30. CAL Data Group Structure Number Of Points (NOP) is a two-byte INTEGER value. This number is equal to the number of complex data that follows the NOP. DATA SEGMENT is a set of the values for each measurement point. The values are IEEE 754 double precision oating number. The values are two numbers (the rst value is the real part, the second value is the imaginary part). The data size in bytes can be determined by 162NOP. Instrument State Block 8-53 Saving and Recalling MEMORY consists of a header and a data segment by a channel. MEMORY TRACE consists of a header and a data segment by a channel. Figure 8-31. MEMORY and MEMORY TRACE Data Group Structure Number Of Points (NOP) of a memory trace is a two-byte INTEGER value. DATA SEGMENT is a set of the values for each measurement point.

Figure 8-32. User Trace Data Group Structure Number Of Points (NOP) is a two-byte integer value. The values of an X-array and Y-arrays are IEEE 754 double precision oating numbers (8 byte length). The data size in bytes for the X-array of each user trace can be determined by 82NOPn (n is the User Trace number). Instrument State Block 8-55 Saving and Recalling File Structure of Internal Data Arrays File for ASCII File Numerical data and strings in an ASCII data le are separated by a tab, and a string is bound by double quotation marks. An ASCII data le consists of a status block and data blocks. Status Block The status block consists of two lines, the revision number and the date code. Data Block The data block consists of three parts, the state part, the title line, and the data part. State The state part consists of the following instrument states: Channel number Title on the screen Measurement parameter Number of points Sweep delay time Point delay time Sweep time Sweep type Point average Source power or CW frequency dc bias Title The title part consists of the data array names saved. Data array names are described in the next section. Data The data part consists of sweep parameter and numerical data of data arrays.

The following subjects are covered in this chapter. System Overview Data Processing Flow System Overview Impedance analyzers usually apply a stimulus signal to the DUT. The analyzer then measures the complex voltage value (which is applied between the terminals of the DUT) and the complex current (which is owing through the DUT). The impedance value is derived from both the voltage and current values. Figure 9-1 is a simpli ed block diagram of the analyzer. A detailed block diagram of the analyzer is provided in the Service Manual, together with a complete theory of system operation. Figure 9-1. Analyzer Simpli ed Block Diagram Analyzer Features 9-1 Data Processing Data Processing Overview Note 9-2 Analyzer Features The analyzer's receiver converts the input signal into useful measurement information. This conversion occurs in two main steps. First, the high frequency input signal is translated to xed low frequency IF signals using analog mixing techniques. Second, the IF signals are converted into digital data by an analog-to-digital converter (adc). From this point on, all further signal processing is performed mathematically by the analyzer microprocessor and digital signal processor. The following paragraphs describe the sequence of math operations and the resulting data arrays as the information ows from the ADC to the display. They provide a good foundation for understanding most of the measurement functions and the order in which they are performed. Figure 9-2 is a data processing ow diagram that shows the ow of numerical data from the ADC to the display. The data passes through several math operations (shown as single-line boxes). Most of these operations can be selected and controlled by the front panel MEASUREMENT block menus. The data is also stored in data arrays (shown as double-line boxes). These arrays are places in the ow path where the data is accessible via GPIB or by using the oppy disk drive or the memory disk. Figure 9-2 also shows other data arrays (shown as double-dotted-line boxes). These arrays are not accessible via GPIB, but showing them may help you better understand the behavior of the instrument. While only a single ow path is shown, two identical paths are available that correspond to channel 1 and channel 2. When the channels are uncoupled, each channel can be independently controlled so that the data processing operations for one can be di erent from the other. Data Processing Data Processing Flow Figure 9-2. Data Processing AD converter (adc) The adc converts an analog signal (which is already down-converted to a xed low frequency IF) into digital data. Digital Filter The digital lter detects the IF signal by performing a discrete Fourier transform (DFT) on the digital data. The samples are converted into complex number pairs (real plus imaginary, R+jX) that represent both the magnitude and phase of the IF signal. Analyzer Features 9-3 Data Processing Ratio Processing The ratio processing calculates the ratio of the current and voltage values (V/I) in order to convert them to an impedance value. Fixed Point Calibration Coecient Arrays and User De ned Point Calibration Coecient Arrays When a calibration measurement is performed, the coecient values at each calibration measurement point are stored in these arrays. These arrays are not accessible via GPIB. Calibration Coecient Interpolation When calibration measurements have been performed or stimulus settings have been changed, the calibration coecients at the current measurement points are calculated from either the xed point calibration coecient arrays or the user de ned point calibration coecient arrays. When the current measurement point is di erent from the calibration measurement point, the coecient value is interpolated from the xed point calibration coecient arrays or the user de ned point calibration coecient arrays. Calibration Coecient Arrays Because the analyzer measures the three standards at three di erent OSC levels automatically when the calibration measurement is performed, calibration data arrays consist of nine arrays. These arrays are directly accessible via GPIB, or by using the oppy disk drive or the memory disk. Error Collection When a measurement calibration has been performed, error correction removes the repeatable systematic errors (stored in the calibration coecient arrays) from the raw data arrays. See \4Cal5" in Chapter 5 and \Calibration Concepts" in Chapter 11 for details. Averaging This is one of the noise reduction techniques. Two types of averaging techniques are provided, sweep averaging and point averaging (the point averaging processes before the ratio processing). The sweep averaging calculation involves taking the complex exponential average of up to 999 consecutive sweeps. The point averaging calculation involves taking the complex average of up to 999 measurements on each measurement point. See \4Bw/Avg5" in Chapter 5. Raw Data Arrays These arrays store the results of all the preceding data processing operations. These arrays are directly accessible via GPIB, or using the oppy disk drive or the memory disk.

Fixture Compensation Coecient Arrays When a xture compensation measurement has been performed and xture compensation is turned on, the xture compensation removes the repeatable systematic error. This error is caused by stray and residual impedance along the xture used. This error information is stored in the xture compensation arrays by the port extension process. See \4Cal5" in Chapter 5 and \Calibration Concepts" in Chapter 11 for details. When the permittivity measurement test xture is selected, these arrays are not used. These arrays are directly accessible via GPIB, or by using the oppy disk drive or the memory disk. Fixed Point Fixture Compensation Coecient Arrays and User De ned Point Fixture Compensation Coecient Arrays When a compensation measurement is performed, the coecient values at each compensation measurement point are stored in these arrays. These arrays are not accessible via GPIB. Compensation Coecient Interpolation When compensation measurements have been performed, stimulus settings have been changed, or compensation is turned on, the compensation coecient at the current measurement points is calculated from either the xed point xture compensation coecient arrays or the user de ned point xture compensation coecient arrays. When the current measurement point is di erent from the compensation measurement point, the coecient value is interpolated from the xed point xture compensation coecient arrays or user de ned point xture compensation coecient arrays. Fixture Compensation When a xture compensation measurement has been performed and this function is turn on, xture compensation removes the errors caused by the test xture. See \Fixture Compensation" in Chapter 11 for details. Data Arrays The results of error correction are stored in the data arrays as complex number pairs. These arrays are accessible via GPIB or by using the oppy disk drive or the memory disk. Memory Arrays If the data-to-memory operation is performed, the data arrays are copied into the memory arrays (data trace arrays are also copied into the memory trace array at same time). See \4Display5" in Chapter 5 in this chapter. These arrays are accessible using the oppy disk drive or the memory disk. These arrays are also output via GPIB, but data cannot be input into this array via GPIB. Analyzer Features 9-5 Data Processing If memory is displayed, the data from the memory arrays goes through the same data processing ow path as the data from the data arrays. Format This converts the complex number pairs into a scalar representation for display, according to the selected format. These formats are often easier to interpret than the complex number representation. (Polar, Smith, admittance chart, and complex plane formats are not a ected by the scalar formatting.) Data Math This calculates the complex ratio of the two (data/memory), the di erence (data0memory), summation (data+memory), or multiplication (data2memory) when the data math function is selected. In addition, this function multiplies the ratio, or di erence by a constant. Data Trace Arrays The results are stored in the data trace arrays. It is important to note those marker values and marker functions are all derived from the data trace arrays. Limit testing is also performed on this array. The data trace arrays are accessible via GPIB, or using the oppy disk drive or the memory disk. Memory Trace Arrays If the data-to-memory operation is performed, the data trace arrays are copied into the memory trace arrays (data arrays are also copied into the memory array at same time). These arrays are accessible using the oppy disk drive or the memory disk. These arrays are also output via GPIB, but data cannot be input into these arrays via GPIB. Scaling These operations prepare the formatted data for display on the LCD. This is where the appropriate reference line position, reference line value, and scale calculations are performed.

Options and Accessories 10-5 Impedance Measurement Basics 11 This chapter introduces the following basic concepts of impedance measurements: Impedance Parameters Series and Parallel Circuit Models Smith Chart Calibration Concepts Port Extension Fixture Compensation Permittivity Measurements Permeability Measurements Impedance Measurement Basics 11-1 11-2 Impedance Measurement Basics Impedance Parameter Impedance parameters All circuit components, resistors, capacitors, or inductors, have parasitic components lurking in the shadows waiting for the unwary, for example unwanted resistance in capacitors, unwanted capacitance in inductors, and unwanted inductance in resistors. Thus, simple components should be modeled as complex impedances, for in fact that is what they are. _ Impedance (Z) Figure 11-1 (a) shows the complex impedance de nitions and Figure 11-1 (b) shows the vector representation of complex impedance. Impedance, Z_ is the total opposition that a circuit or device o ers to the ow of alternating current at a given frequency. Z_ contains a real and an imaginary part, and it is expressed in rectangular form as Resistance and Reactance, or in polar form as magnitude of Impedance and Phase as follows. (11 0 1) Z_ = R + jX = jZj 6 jZj = p (11 0 2) R2 + X2 jXj = arctan R R = Rs (11 0 3) (11 0 4) Where, Complex Impedance [ ] Z_ : R : Resistance [ ] X : Reactance [ ] jZj : Magnitude of Impedance [ ] : Phase of Impedance [deg or rad] Rs : Series Resistance [ ] Figure 11-1. De nition of Impedance The following parameters can be used to represent the reactance. X = 2fL (11 0 5) Impedance Measurement Basics 11-3 Impedance Parameter Where, f: Frequency [Hz] L: Inductance [H] In addition to these parameters, the Quality Factor (Q) and Dissipation Factor (D) are used to describe the quality of components. 1 jX j (11 0 6) Q= = D R Where, Q : Quality Factor D : Dissipation Factor _ Admittance (Y) 11-4 Impedance Measurement Basics In some case, the dual of impedance (Admittance), Y_ is used. Figure 11-2 shows the vector representation of admittance. As Z_ (Complex Impedance), Y_ is composed of a real and an imaginary part, and is expressed in rectangular form as Conductance and Susceptance, or in polar form as magnitude of Admittance and Phase. The following are expressions for Admittance. 1 Y_ = _ (11 0 7) Z (11 0 8) Y_ = G + jB = jYj 6 p 2 2 1 (11 0 9) jYj = G + B = jZj jBj = 0 = arctan (11 0 10) G B = 2fC (11 0 11) 1 jBj Q= = (11 0 12) D G 1 G= (11 0 13) Rp Where, Y_ : Complex Admittance [S] G : Conductance [S] (real) B : Susceptance [S] (imaginary) jYj : Magnitude of Admittance [S] : Phase of Admittance [deg or rad] C: Capacitance [F] Rp : Parallel Resistance [ ] Impedance Parameter Figure 11-2. Vector Representation of Admittance _ Re ection Coecient (0) When measuring RF impedance , the re ection and/or transmission coecient parameter values are usually measured by a network analyzer or RF impedance analyzer. The 4291B provides the re ection coecient 0_ as measurement parameter. The re ection coecient 0_ is de ned as: V_ (11 0 14) 0_ = _ref = 0x + j 0y = j0_ j(cos + j sin ) = j0_ j6 Vinc where, V_ ref is voltage of the re ected wave V_ inc is voltage of the incident wave The re ection coecient value and the impedance value of the sample is interrelated, each with the other, by the following formulas: Z_ 0 Z0 0_ = _ x (11 0 15) Zx + Z0 1 + 0_ Z_ x = Z0 (11 0 16) 1 0 0_ where, Z0 is characteristic impedance. Impedance Measurement Basics 11-5 Series and Parallel Circuit Models Series and Parallel Circuit Models An impedance element can be represented by a simple equivalent circuit consisting of resistive and reactive elements (connected in series with or in parallel with each other). This representation is possible by either of the equivalent (series or parallel) circuits because both have identical impedances at the selected measurement frequency. These values are obtained by properly selecting the value of the equivalent circuit elements. The 4291B can select the model by setting the measurement parameter (R, X, G, B, Cp , Cs , Lp , or Ls ) using the 4Meas5 key. To determine which circuit model is best, consider the relative impedance magnitude of the reactance and Rs and Rp . Table 11-1. Parallel/Series Circuit Model and Measurement Parameter Parallel Circuit Model Series Circuit Model Parallel-Series Equivalent Circuit Conversion Parameter values for a component measured in a parallel equivalent circuit and that measured in a series equivalent circuit are di erent from each other. The di erence in measured values is related to the loss factor of the sample to be measured. If no series resistance or parallel conductance is present, the two equivalent circuits are identical. However, the sample value measured in a parallel measurement circuit can be correlated with that of a series circuit by a simple conversion formula that considers the e ect of the dissipation factor (D). See Table 11-2. The dissipation factor of a component always has the same value at a given frequency for both parallel and series equivalent circuits. 11-6 Impedance Measurement Basics Series and Parallel Circuit Models Table 11-2. Dissipation Factor Equations and Parallel-Series Equivalent Circuit Conversion Device Circuit Mode C Dissipation Factor D= 1 1 = 2f Cp Rp Q Conversion to other modes Cs = (1 + D2 )Cp Rs = C D = 2f Cs Rs = 1 Q Cp = Rp = L D= 2f Lp Rp = 1 Q Ls = Rs = L D= Rs 2f Ls = 1 Q D2 1 + D2 Rp 1 Cs 1 + D2 1 + D2 D2 Rs 1 Lp 1 + D2 D2 1 + D2 Rp Lp = (1 + D2 )Ls Rp = 1 + D2 D2 Rs Selecting Circuit Mode of Capacitance The following description gives some practical guide lines for selecting the capacitance measurement circuit mode. Small Capacitance Small capacitance yields a large reactance, that implies that the e ect of the parallel resistance (Rp ) has relatively more signi cance than that of the series resistance (Rs ). The low value of resistance represented by Rs has negligible signi cance compared with the capacitive reactance, so the parallel circuit mode (Cp ) should be used (see Figure 11-3). Figure 11-3. Small Capacitance Circuit Mode Selection Impedance Measurement Basics 11-7 Series and Parallel Circuit Models Large Capacitance When the opposite is true and the measurement involves a large value of capacitance (low impedance), Rs has relatively more signi cance than Rp , so the series circuit mode (Cs -D or Cs -Q) should be used (see Figure 11-4). Figure 11-4. Large Capacitance Circuit Mode Selection The following is a rule of thumb for selecting the circuit model according to the impedance of the capacitor: Above approx. 10 k : Use parallel circuit model. Below approx. 10 : Use series circuit model. Between above values: Follow the manufacturer's recommendation. Selecting Circuit Mode of Inductance The following description gives some practical guide lines for selecting the inductance measurement mode (that is, which circuit mode to use). Large Inductance The reactance at a given frequency is relatively large (compared with that of a small inductance), so the parallel resistance becomes more signi cant than the series component. Therefore, a measurement in the parallel equivalent circuit mode (Lp -D, Lp -Q or Lp -G) is more suitable (see Figure 11-5). 11-8 Impedance Measurement Basics Series and Parallel Circuit Models Figure 11-5. Large Inductance Circuit Mode Selection Small Inductance For low values of inductance, the reactance becomes relatively small (compared with that of a large inductance) so the series resistance component is more signi cant. Therefore, the series equivalent circuit mode (Ls -D or Ls -Q) is appropriate (see Figure 11-6). Figure 11-6. Small Inductance Circuit Mode Selection The following is a rule of thumb for selecting the circuit model according to the impedance of the inductor: Below approx. 10 : Use series circuit model. Above approx. 10 k : Use parallel circuit model. Between above values: Follow the manufacturer's recommendation. Impedance Measurement Basics 11-9 Smith Chart Smith Chart This section provides a brief description of the Smith Chart for users who are not familiar with its use. Figure 11-7 shows the Smith Chart plane of impedance coordinates. On the Smith Chart plane, the coordinate scales signify the impedance component quantities. The circles tangent at point a are the scales for which the resistance values (R) are constant. The arcs that cross at point a and intersect the circles at right angles are the scales for which reactance values (X) are constant. Figure 11-7. Smith Chart These resistance and reactance scale values are the normalized values. They are calculated by dividing the sample impedance (Zx =Rx +jXx ) by the characteristic impedance (Zo=50 ) of the measuring circuit. Therefore, the normalized impedance Rr + jXr is : Rr + jXr = Zx Rx jXx = + 50 Z0 50 (11 0 17) A sample impedance value is represented on the Smith Chart as a point coordinated with the scales corresponding to its normalized impedance (see Figure 11-8). The base impedance Z0 (characteristic impedance) is located at the center of the Smith Chart plane. The radius vector Z0 1Zr represents the re ection coecient value j0j6 of the sample (in this case, the electrical length of the transmission line is not being taken into consideration). The phase angle scales for the re ection coecient vector are provided along the outer circumference of the Smith Chart. The phase angle of the re ection coecient can be read from the phase angle scale as indicated by an extension of the vector Z01Zr . The absolute value of the re ection coecient j0j is constant at any point on the circle of the radius Z01Zr . 11-10 Impedance Measurement Basics Smith Chart Figure 11-8. Impedance Read-out When a coaxial cable of line length l is terminated by the sample and the cable is lossless, the impedance value of the sample measured at the other end of the line is derived as follows: First, the di erence in phase angle of the re ection coecient value 0 (produced by the lead length l) is calculated using the following equation: 4l (11 0 18) = Where, is the wavelength of test signal. Next, the radius vector Z0 1Zx is rotated clockwise (towards the generator) by the calculated phase angle . The measured impedance value (normalized impedance) coincides with the scale reading at point Zm (see Figure 11-9). Figure 11-9. Phase Sift by Transmission Line Impedance Measurement Basics 11-11 Calibration Concepts Calibration Concepts This section describes the basic concepts of OPEN SHORT LOAD calibration and Low-Loss air-capacitor calibration. The Low-Loss air-capacitor calibration improves the accuracy of the phase measurements. OPEN SHORT LOAD Calibration Ideal Measurement Circuit Figure 11-10 (a) shows the basic measurement circuits for the I-V method. This method uses two vector voltmeters Vv and Vi (Vv detects the vector voltage applied to the DUT and Vi detects the vector current owing through the DUT). Assuming that the measurement circuit is ideal (which means there is no stray admittance and no residual impedance), and the impedance values of all the components in the measurement circuit are exactly correct, the DUT's impedance value Z_ x is calculated using the following equations: V_ Z_ x = R _v (11 0 19) Vi Figure 11-10. Measurement Circuits for I-V Method Figure 11-10 (b) and (c) show the simpli ed measurement circuits of the high impedance test head and the low impedance test head of the analyzer. The DUT's impedance value (Z_ x ) is calculated using the following equations (if the measurement circuit is ideal): For the high impedance test head (Figure 11-10-(b) ), Z_ x is : R V_ Z_ x = 0 ( _v 0 1) (11 0 20) 2 Vi For the low impedance test head (Figure 11-10-(c) ), Z_ x is : 2R Z_ x = _ 0 (11 0 21) Vi 0 1 V_ v 11-12 Impedance Measurement Basics Calibration Concepts General Impedance Measurement Schematic However, actual measurement circuits have some error terms (such as stray admittance and residual impedance) plus, the components of the circuit also have some errors. In addition, the four resistances (R0) in the measurement circuit do not have exactly the same impedance value. In fact, the impedance values calculated from the above equations do not correspond with the actual impedance value of the DUT. Generally, an impedance measurement circuit using two vector voltmeters is represented as shown in Figure 11-11. Figure 11-11. General Schematic for Impedance Measurement Using Two Vector Voltmeters This general impedance measurement circuit uses two vector voltmeters. These two voltmeters can measure at any two di erent points in a linear circuit. In this case, the DUT's impedance can be expressed by the measured voltage values (V_ v and V_ i ) using a bilinear form as follows: 1 + b_ r_ (11 0 22) Z_ x = a_ 1 + c_ r_ Where, _ c_ are complex constants a, _ b, r_ is a ratio between V_ v and V_ i as follows: V_ (11 0 23) r_ = _v Vi In general, Z_ x can be expressed using the above bilinear form whenever the measurement circuit is linear. By using the measurement impedance value (Z_ m ) instead of the voltage ratio r_ and modifying the equation, Z_ x can also be expressed using the following bilinear form: Z_ 0 B_ (11 0 24) Z_ x = A_ m _ _ 1 0 C Zm _ B, _ and C_ are complex constants (calibration coecients) Where, A, related to the circuit. If three standards that have known impedance value are measured, these three constants can be calculated. The analyzer uses the Impedance Measurement Basics 11-13 Calibration Concepts OPEN, SHORT, and LOAD standards (furnished) for the calibration. Once these constants are known, any impedance of the DUT can be calculated from the measured impedance value. Where, B_ represents residual impedance when the circuit is perfectly shorted and C_ represents stray admittance when the circuit is perfectly open. Low Loss Capacitor Calibration Accurate Q measurements require good analyzer stability and correct markings on the phase scale of the analyzer. In particular, high Q (or low D : dissipation factor) measurements at high frequencies require high accuracy for phase measurements. The phase accuracy of the analyzer is determined entirely by the OPEN SHORT LOAD calibration. But, it is not guaranteed that the phase uncertainty for a 50 LOAD at high frequencies is lower than the uncertainty requirement for a high Q measurement. For example, if you want to measure the Q factor with 10% of uncertainty for a DUT whose Q value is almost 100, the uncertainty for phase scaling must be less than 1003 . But, it is dicult to ensure that the phase uncertainty for the 50 LOAD is less than 1003 at high frequencies. To reduce the uncertainty of the measured phase, the analyzer uses a low-loss air-capacitor as a phase standard, whose dissipation factor (D) is kept below 1003 at around 1 GHz. The following steps show how the analyzer improves phase measurement accuracy using a low-loss air-capacitor: 1. Measure the OPEN, SHORT, and LOAD standards and the Low-Loss air-capacitor. 2. Assuming the impedance of the 50 LOAD is Z_ ls = 50 ej0 (that is, the phase of 50 LOAD is zero) as shown in Figure 11-12-(a) ), _ B, _ and C_ . calculate the calibration coecient A, 3. Execute the correction for the Low-Loss air-capacitor and get the corrected impedance value of the Low-Loss air-capacitor. (Z_ cc ) 4. Calculate the phase di erence (1) between the phase of Z_ cc and the true phase of the Low-Loss air-capacitor (see Figure 11-12-(b)). (11-25) 1 = cc 0 cs Where, cc = arg (Z_ cc) cs is standard phase value of the Low-Loss air-capacitor. 5. Modify the impedance of the 50 LOAD to Z_ lc whose phase is 01 and whose impedance magnitude is still 50 (see Figure 11-12-(c)). The modi ed impedance value of 50 LOAD Z_ lc is expressed in the following equation: Z_ lc = 50 e0j1 11-14 Impedance Measurement Basics (11-26) Calibration Concepts _ B, _ and C_ again by normal 6. Calculate the calibration coecients A, OPEN SHORT LOAD calibration using the modi ed 50 LOAD impedance value Z_ lc . The analyzer performs this procedure automatically when a Low-Loss air-capacitor is measured in the calibration menu. Although this is an approximate method, just performing these procedures make the analyzer accurate enough to perform high Q measurements. Figure 11-12. Modifying the Standard Value of a 50 LOAD using a Low-Loss Air-Capacitor Low-Loss Air-Capacitor calibration does not a ect the measurement below 300 MHz In fact, taking frequency into consideration, the analyzer uses the following equations for Z_ lc : Z_ lc = 50 e0jk1 Where, k is a constant that depends on the measurement frequency. Because the phase of 50 LOAD at a low frequency is regarded as zero, the analyzer uses the following value as k: k = 0 (at frequency 300 MHz) k= f[M H z ] 0 300 500 0 300 (at 300 MHz < frequency 500 MHz) k = 1 (at frequency > 500 MHz) Impedance Measurement Basics 11-15 Port Extension Port Extension When the extension cable is used to extend the measurement plane from APC-7 R of the head to the tip of the cable, the measurement error increases because of the additional impedance in a distributed element circuit of the cable. To minimize the measurement errors, the port extension function simulates a variable length lossless cable that can be added to or removed from the test port to compensate for interconnecting cables, test xtures, etc. The value of port extension is annotated in units of time with secondary labeling in distance for the velocity of light. An estimated impedance value through this function is calculated according to the following concept: Figure 11-13. Port Extension When impedance ZL is connected to one tip of extension cable as shown in Figure 11-13, the input impedance from the other tip of cable is expressed using the following equation: Z + Z0 tanh( _ l) (11 0 27) Zin = Z0 L Z0 + ZL tanh( _ l) Where, Z0 is the characteristic impedance of the cable. l is the electrical length of the cable representing the physical length of the cable (l0 ) and the relative permittivity of the material in the cable ("r ) : p l = "r l0 _ is propagation coecient and expressed as: _ = +j where, is attenuation constant is phase constant Assuming that the cable is lossless, conditions: =0 ! = c0 where, 11-16 Impedance Measurement Basics (11 0 28) (11 0 29) and satisfy the following (11 0 30) (11 0 31) Port Extension c0 is the velocity of light Therefore, ! tanh( _ l) = tanh(j l) c0 ! = j tan( l) c (11 0 32) 0 Because the characteristic impedance of the extension cable for the analyzer should be 50 , Z0 is constant as follows: (11 0 33) Substitute these conditions into the equation for Zin. Then modify it in order to calculate ZL from Zin . ZL can be determined by using the following equation: Z 0 j 50 tan(!1t) (11 0 34) ZL = 50 in 50 0 jZin tan(!1t) Z0 = 50 + j 0 Where, 1t is port extension in time [sec] 1t = l c0 When the linear portion of the DUT's phase is removed using the port extension function, the electrical length of the DUT can be read in the active entry area of the display. Setting Proper Electrical Length Compensation You can easily check to determine whether the electrical length can t the extended measurement circuit. Proceed as follows: 1. Perform calibration without using an extension cable. 2. Connect the extension cable (or the unknown xture) to the test port. 3. Set the measurement parameter to j0j. 4. Set the measurement format to Smith chart format. 5. Set the Smith/polar marker to Logmag-Phase. 6. Connect a 0 S termination at the tip of the extension cable (or an open at the tip of the extension cable). 7. Turn the port extension on. 8. Change the port extension value until the values measured are 0 at any frequency point. Impedance Measurement Basics 11-17 Port Extension Another Method of Canceling the Measurement Error Caused by Extension Cable The OPEN1SHORT1LOAD xture compensation cancels the error caused by port extension. To cancel the error: 1. Perform calibration at the tip of APC-7 R on the test head without using an extension cable. 2. Connect the extension cable and the test xture to be used. 3. Perform OPEN, SHORT, and LOAD xture compensations. It is necessary to perform calibration measurement at the APC-7 R connector of the test head. If calibration is performed at the tip of the extension cable, the calibration error would increase. OPEN, SHORT or OPEN and SHORT compensations can not cancel the error caused by the extension cable. It is the best way to perform the OPEN SHORT LOAD xture compensation if the LOAD performance is perfectly known. 11-18 Impedance Measurement Basics Fixture Compensation Fixture Compensation Actual Measuring Circuit The measuring circuit connecting a test sample to the test port (that is, the test xture) actually becomes part of the sample that the instrument measures. In addition, component electrodes or leads, which should essentially be of negligibly low impedance, also in uence the measured sample values because of the presence of certain parasitic impedances. Diverse parasitic impedances existing in the measuring circuit between the test port and the unknown device a ect the measurement result. These parasitic impedances are present as resistive or reactive factors in parallel or in series with the sample device. Furthermore, in the high frequency region, the equivalent electrical length of the measuring circuit, including component leads, rotates the measured impedance vector as function of the test signal wavelength. Let's discuss the e ects that increase measurement uncertainties. Residual Parameter E ects Figure 11-14 shows an equivalent circuit model of the measuring circuit that includes unknown component and parasitic parameters (usually called residual parameters). These residual parameters cause two kinds of measurement errors, which are described in the following paragraphs. Figure 11-14.

Characteristics of Test Fixture Electrical Length of Coaxial Coupling Terminal Section The test xtures are basically composed of two major components, a coaxial coupling terminal and the contact electrodes (terminals), combined in one unit. The electrical length value speci ed for each type of xture is calculated for the coaxial coupling terminal and does not include the electronic factors in the electrodes. As the coaxial coupling terminal section of the xtures is a distributed constant circuit design (50 ), this xture section is virtually an extension of the test port. The inherent e ect in the coaxial coupling terminal is represented by the electrical length value particular to the test xture. On the other hand, the contact section (that is, the electrodes on the xtures) has di erent characteristics from the 50 distributed constant test port. Elimination of Electrical Length E ects in Test Fixture The 4291B has a typical electrical length for the speci ed test xtures. When a test xture is selected, the 4291B automatically sets the typical electrical length value for the xture selected. The technique to eliminate the electrical length uses the same technique as the port extension function. See \Port Extension", for more information on port extension. Residual and Stray Parameters of Contact Electrode Section The contact electrode (terminal) section can not be regarded as part of the distributed constant circuit. Because a correction calculation performed on the basis of the test xture selection (provided by the 4291B) does not compensate for the residual and stray parameters in the contact section, these residuals and strays contribute to measurement errors. The residual and stray factors in the test xtures is illustrated in Figure 11-14. 11-20 Impedance Measurement Basics Fixture Compensation Elimination of Residual Parameter E ects in Test Fixture (Fixture Compensation) In general, these residual and stray factors can be represented by F parameters of 2 terminal-pair as shown in Figure 11-16. Using this model, the residual and stray factors can be eliminated. Figure 11-16. Test Fixture Represented by the F matrix of a Two Terminal Pair Network V1 = A B V2 (11 0 35) I1 C I2 D The actual impedance value of the DUT (Zx ) and the measurement value (Zm ) are represented by the input and output current and voltage as follows: V1 I1 V Zx = 2 I2 Zm = Then, Zx is: Zx = Acompen Where, Zm 0 Bcompen 1 0 Zm Ccompen (11 0 36) (11 0 37) (11 0 38) Acompen = D/A Bcompen = B/D Ccompen = C/A There are three unknown parameters. Therefore, three standards are needed for perfect compensation. When Acompen , Bcompen , and Ccompen are given, Zx is calculated. To get Acompen, Bcompen , and Ccompen , the 4291B executes measurements for OPEN, SHORT, and LOAD compensation. Impedance Measurement Basics 11-21 Fixture Compensation Compensation Coecient for Each Compensation For xture compensation, three compensations (OPEN, SHORT, and LOAD) are provided for the analyzer. These compensations can be turned on individually. After the compensation measurements have been done and tuned on, the compensation coecients, Acompen , Bcompen , and Ccompen , are automatically calculated and the measurement value Zm is transformed to Zx through the equation (11-45). Some assumptions are made for compensations except for OPEN1SHORT1LOAD xture compensation. The following paragraphs show the conditions assumed for each combination and the equations used for each combination of the OPEN, SHORT and LOAD xture compensations. OPEN Compensation When only the OPEN compensation is used for the xture compensation, two additional conditions are required to solve the Zx equation. One condition assumes that the equivalent circuit model of the xture used is a symmetric circuit. The other condition assumes that SHORT measurement capability is ideal, that is, the measurement value for perfect SHORT standard equals to perfect SHORT value. These conditions are explained as follows: Assuming that : A=D (symmetric circuit) (11-39) B=0 (11-40) Then, the compensation coecients are: Acompen = 1 + j0 (11-41) Bcompen = 0 + j0 (11-42) Ccompen = Yom 0 Yos (11-43) Where, Yom is the admittance value measured under open condition Yos is the admittance value de ned as OPEN as the xture compensation kit SHORT Compensation When only the SHORT compensation is used for the xture compensation, two additional conditions are required to solve the Zx equation. One condition assumes that the equivalent circuit model of the xture used is a symmetric circuit. The other condition assumes that OPEN measurement capability is ideal, that is, the measurement value for perfect OPEN standard equals to perfect OPEN value. These conditions are explained as follows: Assuming that : A=D (symmetric circuit) (11-44) C=0 (11-45) Then, the compensation coecients are: 11-22 Impedance Measurement Basics Fixture Compensation Acompen = 1 + j0 (11-46) Bcompen = Zsm 0 Zss (11-47) Ccompen = 0 + j0 (11-48) Where, Zsm is the impedance of the value measured for shorted device. Zss is the impedance value de ned as SHORT for the xture compensation kit LOAD Compensation When only the LOAD compensation is used for the xture compensation, two additional conditions are required to solve the Zx equation. One condition assumes that the value measuring shorted device is the same as the value de ned as SHORT for the xture compensation kit. The other condition assumes that SHORT measurement capability is ideal and OPEN measurement capability is ideal. These conditions are explained as follows: Assuming that : B=0 (11-49) C=0 (11-50) Then, the compensation coecients are: Acompen = ZZl lm (11-51) Bcompen = 0 + j0 (11-52) Ccompen = 0 + j0 (11-53) Where, Zlm is the impedance value measured for load device Zls is the impedance value de ned as LOAD of the xture compensation kit OPEN-SHORT Compensation When OPEN and SHORT compensations are used for the xture compensation, one additional condition is required to solve the Zx equation. This condition is explained as follows: Assuming that : A=D (symmetric circuit) (11-54) Then, the compensation coecients are: Acompen = 1 + j0 (11-55) Z 0 (1 0 Yom Zsm )Zss 0 Zsm Yos Zss Bcompen = sm (11-56) 1 0 Yom Zsm Yos Zss Ccompen = Yom 0 (1 0 Yom Zsm )Yos 0 Yom Yos Zss 1 0 Yom Zsm Yos Zss (11-57) Impedance Measurement Basics 11-23 Fixture Compensation OPEN-LOAD Compensation When OPEN and LOAD compensations are used for the xture compensation, one additional condition is required to solve the Zx equation. The condition assumes that SHORT measurement capability is ideal, that is, the measurement value for perfect SHORT standard equals to perfect SHORT value. This condition is explained as follows: Assuming that : B=0 (11-58) Then, the compensation coecients are: Y 0 Yom Acompen = lm (11-59) Yls 0 Yos Bcompen = 0 + j0 Y Y 0 Ylm Yos Ccompen = om ls Yls 0 Yos (11-60) (11-61) SHORT-LOAD Compensation When SHORT and LOAD compensations are used for the xture compensation, one additional condition is required to solve the Zx equation. The condition assumes that SHORT measurement capability is ideal, that is, the measurement value for perfect OPEN standard equals to perfect OPEN value. This condition is explained as follows: Assuming that : C=0 (11-62) Then, the compensation coecients are: Z 0 Zls Acompen = ss (11-63) Zsm 0 Zlm Bcompen = Zlm Zss 0 Zsm Zls Zss 0 Zls Ccompen = 0 + j0 (11-64) (11-65) OPEN-SHORT-LOAD Compensation When OPEN, SHORT and LOAD compensations used for the xture compensation, no more conditions are required to solve the Zx equation.

Schematic Electrode Structure of the 16453A In general, when a dielectric material is put in a pair of parallel at electrodes, capacitance C is calculated using the following equation: C = "0 "r Complex Permittivity S t (11 0 69) Strictly speaking, when ac voltage is applied to the dielectric material, the material has some loss and permittivity "r is de ned as the following complex value: (11 0 70) "_ r = "0 0 j"00 r r Now, the capacitor has a loss factor and the capacitance C in equation (11-76) can be modi ed to the complex admittance Y_ as follows: Y_ C 0! (11 0 71) j! Y_ S = "0 "_ r j! t (11 0 72) Figure 11-18. Material has some loss Therefore, the relative permittivity of the MUT can be obtained using the following equation: 1 Y_ m t "_ r = "0 j! S 11-26 Impedance Measurement Basics Permittivity Measurements = Where, Y_ m j!C0 (11 0 73) Y_ m is the measurement admittance value of the MUT. C0 is the capacitance value of the air gap (whose distance between electrodes is same as the thickness of the MUT). C0 = "0 S d (11 0 74) Characteristics of Test Fixture Edge E ect When the capacitance of the material is measured, stray capacitance exists at edge of electrodes (see Figure 11-19). Figure 11-19. Edge E ect Because measurement result is a summation of the capacitance of a MUT and the stray capacitance caused by the edge e ect, the edge e ect is generally expressed as follows: C0(1 + Eedge ) (11 0 75) Where, Eedge is the compensation coecient for the edge e ect, which is determined by the gap between electrode and relative permittivity of MUT. Adding the edge e ect to C0 in equation (11-73), the relative permittivity of the MUT can be obtained by using the following equation: Y_ m (11 0 76) "_ r = j!C0 (1 + Eedge) Impedance Measurement Basics 11-27 Permittivity Measurements The Analyzer uses an approximately value as Eedge of 16453A The analyzer uses the following approximate value of Eedge for the 16453A: Eedge = 434t0:825 "0r 00:554 where, t : [m] Residual Parameter In fact the 16453A has residual impedance and stray admittance, which cause an increased error when measuring the admittance of the MUT. To eliminate residual and stray admittance, the OPEN, SHORT, and LOAD xture compensations are required for any permittivity measurement using the 16453A. Because the equation to compensate for measurement admittance value is same as the equation for the OPEN-SHORT-LOAD xture compensation for impedance measurement, see \Fixture Compensation" for more information on OPEN, SHORT, and LOAD xture compensation. 11-28 Impedance Measurement Basics Permeability Measurements Permeability Measurements In general, when current is owing along an in nity line (as shown in (a) of Figure 11-20), magnetic ux density B is generated by the current as follows: B = I (11 0 77) 2r When current is owing in a closed loop (as shown in (b) of Figure 11-20), the magnetic ux 8 generated by the current is : 8 = LI (11 0 78) Where, L is the self-inductance of the closed loop. Because the magnetic ux is calculated by the surface integral of the magnetic ux density B (s shown in (C) of Figure 11-20), 8 is also expressed by the following equations: Z 8 = B ds (11 0 79) Figure 11-20. Basic Relationship of Magnetic Flux Density, Magnetic Flux, and Current Figure 11-21 shows the schematic xture structure of the 16454A. Figure 11-21. Schematic Fixture Structure of 16454A Impedance Measurement Basics 11-29 Permeability Measurements The 16454A measures core shape magnetic material as shown in Figure 11-21. Erasing B and 8 and considering the physical shape and dimensions of the 16454A, the self-inductance of the measurement circuit including MUT is derived as follows: Z L = 1I B ds = = Z Z d h0 a 0 dr dz 2r (11 0 80) c do 0 n (r 0 1)h ln + h0 ln b a 2 (11 0 81) Modify equation (11-87) to get the relative permeability r of MUT: 2 L 0 Lss +1 r = (11 0 82) F 0 Where, Lss is the self-inductance of the xture when it is empty. Lss = 0 b h0 ln 2 a (11 0 83) F is the shape function of MUT, which is decided by its dimensions only. F = h ln Complex Permeability a b (11 0 84) When the magnetic eld generated by an ac current is owing is applied to the magnetic material, the permeability is de ned by the complex value shown in equation (11-92). _ r = 0 0 j00 (11 0 85) r r Now, because the inductor has a loss factor, the inductance in equations (11-87) through (1-89) must be modi ed to a complex impedance, which includes the loss: Z_ L 0! (11 0 86) j! Figure 11-22. Material Has Loss The complex relative permeability of the MUT can then be determined by the following equation: 11-30 Impedance Measurement Basics Permeability Measurements Z_ 0 Lss 2 j! +1 _ r = 0 F (11 0 87) _ and calculates _ r using this The analyzer measures impedance (Z) equation. Characteristics of the Test Fixture Residual Parameter The 16454A has residual impedance. The residual impedance Z_ res is represented by a series impedance as shown in Figure 11-23. Figure 11-23. Residual Impedance of the 16454A Assuming that the impedance value of the empty test xture is known, the residual impedance can be speci ed by measuring the xture with no MUT (empty). Z_ res = Z_ sm 0 Z_ ss (11 0 88) Where, Z_ ss is the ideal value of the impedance when the xture is empty. Z_ sm is the measurement value of the impedance when the xture is empty. Elimination of Residual Impedance E ects in the Test Fixture (SHORT Fixture Compensation) The SHORT xture compensation can eliminate the residual impedance e ect. When the SHORT (empty) compensation measurement has been performed, the compensated impedance Z_ comp can be expressed by the following equation: Z_ comp = Z_ m 0 Z_ res (11 0 89) Assuming that Z_ ss has only an inductance factor (Z_ ss = j!Lss ), and using the compensated impedance value Z_ comp , the permeability of the MUT can be derived from Z_ m and Z_ sm as follows: 2 Z_ m 0 Z_ sm _ r = +1 (11 0 90) 0 j!F Impedance Measurement Basics 11-31 Permeability Measurements Impedance Parameter Value Displayed for Magnetic Material Measurement When the 4291B measures magnetic materials, the impedance parameter value displayed is calculated from the following impedance _ value (Z): c _ Z_ = jwh m 0 ln 2 b Where, _ m is measurement complex permeability value of MUT b is inner diameter of MUT c is outer diameter of MUT 11-32 Impedance Measurement Basics 4291B RF Impedance/Material Analyzer Technical Data 12 Speci cations describe the instrument's warranted performance over the temperature range of 0 C to 40 C (except as noted).

The information in this manual applies directly to the 4291B RF Impedance/Material Analyzer serial number pre x listed on the title page of this manual. Manual Changes To adapt this manual to your 4291B, see Table A-1 and Table A-2, and make all the manual changes listed opposite your instrument's serial number and rmware version. Instruments manufactured after the printing of this manual may be di erent from those documented in this manual. Later instrument versions will be documented in a manual changes supplement that will accompany the manual shipped with that instrument. If your instrument's serial number is not listed on the title page of this manual or in Table A-1, it may be documented in a yellow MANUAL CHANGES supplement. In additions to change information, the supplement may contain information for correcting errors (Errata) in the manual. To keep this manual as current and accurate as possible, Agilent Technologies recommends that you periodically request the latest MANUAL CHANGES supplement. For information concerning serial number pre xes not listed on the title page or in the MANUAL CHANGE supplement, contact the nearest Agilent Technologies oce. Turn on the line switch or execute the *IDN? command by GPIB to con rm the rmware version. See the Programming Manual manual for information on the *IDN? command. Table A-1. Manual Changes by Serial Number Serial Pre x or Number Make Manual Changes Table A-2. Manual Changes by Firmware Version Version Make Manual Changes Manual Changes A-1 Serial Number Agilent Technologies uses a two-part, ten-character serial number that is stamped on the serial number plate (see Figure A-1) attached to the rear panel. The rst ve characters are the serial pre x and the last ve digits are the sux. Figure A-1. Serial Number Plate A-2 Manual Changes Input Range and Default Setting B When the 4Preset5 key is pressed or the analyzer is turned ON, the analyzer is set to a known state. There are subtle di erences between the preset state and the power-up state. Some power-up states are recalled from non-volatile memory (battery backup memory). If power to the non-volatile memory is lost, the analyzer will have certain parameters set to factory settings. Factory Setting lists the factory settings. The operating time of the battery backup memory is approximately 72 hours. The battery is automatically recharged while the instrument is ON. The recharge time (time required to fully recharge the battery) is approximately 10 minutes. When line power is cycled the analyzer performs a self-test routine. Upon successful completion of the self-test routine, the instrument state is set to the following preset conditions. The same conditions are true following a \PRES" or \3RST" command via GPIB.

The analyzer is set to the USER DEFINED calibration automatically. Setting the Test Fixture The test xture should be set on the test head after calibration. The setup for the 16194A is shown in Figure C-3. Figure C-3. 16194A Connection Select your test xture model number using the 4Meas5 hardkey. Fixture Compensation How to perform xture compensation for the 16194A is shown below. For a basic measurement, the Open and Short compensations are required. However, if you use both the 16194A and the High Temperature Test Head for High Impedance, or the measurement frequency is above 500 MHz, the Load compensation is also required. The procedures for the 16453A and 16454A are shown in the applicable Fixture Compensation section in each quick start. C-4 Option 013, 014 Temperature Coecient Measurement Short Compensation Temperature Coecient Measurement 1. Loosen the two knobs. 2. Adjust the stage and the pressure arm to t your shorting device. 3. Move the pressure arm to the outside. 4. Tighten the two knobs. 5. Place the shorting device so that it contacts both electrodes. 6. Release the pressure arm so that the shorting device is held by the pressure arm. Option 013, 014 Temperature Coecient Measurement C-5 Temperature Coecient Measurement Note When it is dicult to connect the device to the test xture that is in the chamber, remove the test xture from the test xture stand. Then connect the device outside the chamber and set the xture on the test xture stand again. When the test xture is ready for the SHORT compensation sequence, press the following front panel keys: 1. Press 4Cal5 FIXTURE COMPEN COMPEN MENU . NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN 2. Press SHORT .

Adjust the stage and the pressure arm to t your DUT. 3. Move the pressure arm to the outside. 4. Turn the latch knob and insert it into the hole so that the pressure is locked. When the test xture is ready for the Open compensation sequence, perform the following procedure: C-6 Option 013, 014 Temperature Coecient Measurement Temperature Coecient Measurement 1. Press OPEN . After the OPEN compensation sequence is done, the OPEN softkey label is underlined. 2. Press DONE: COMPEN if you do not intend to perform the Load compensation. If you use both the 16194A and High Temperature Test Head for High Impedance, or the measurement frequency is above 500 MHz, the Load compensation is required. NNNNNNNNNNNNNN NNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN Load Compensation Connect the Load to the 16194A just as you connected the shorting device in the Short compensation. The Load device is included with 16194A. When the test xture is ready for the Load compensation sequence, perform the following procedure: 1. Press LOAD . After the Load compensation sequence is done, the LOAD softkey label is underlined. 2. Press DONE: COMPEN . NNNNNNNNNNNNNN NNNNNNNNNNNNNN NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN Note When your DUT is leaded type, the compensation procedure is as follows: 1. Perform the Short Compensation using the biggest shorting device (Agilent P/N 16191-29004). 2. Perform the Load Compensation using the furnished load device. 3. Replace the pressure arm pin for SMD with one for a leaded component. 4. Adjust the stage to t your DUT. 5. Perform the Open Compensation. Option 013, 014 Temperature Coecient Measurement C-7 Temperature Coecient Measurement If you use both the 16194A and High Temperature Test Head for Low Impedance, and the measurement frequency is below 500 MHz, the Load compensation is not required. Saving Status File After performing calibration/ xture compensation at your required settings, save the settings with the calibration/ xture compensation data to the status le. In this example, setup A is saved using the name \ZTF". 1. Insert the data diskette (DOS formatted) into the oppy disk drive slot. 2. Press 4Save5 STATE . NNNNNNNNNNNNNNNNN 3. Enter the le name "ZTF" and press 4Return5. 4. The message of "SAVING "ZTF.STA" TO DISK" is displayed. The analyzer saves a status le with a \.STA" extension.
