Advance the INTENSITY control until the trace is at the desired viewing level. The trace should appear near the graticule center. 5. Connecta 1X probe, or a testiead from the amplifier plug-in input connector to the CALIBRATOR loop. 6. Turn the Main Trig Level control clockwise until a stable display is obtained. Adjust the vertical and horizon- tal Position controls so that the display is centered vertically and starts at the left edge of the graticule. 7. Adjust the FOCUS control for a sharp, well-defined display over the entire trace length. 8. Disconnect the input signal and position the trace vertically so thatit coincides with the center horizontal line of the graticuie. 9. If the trace is not paralie! with the center horizontal line, see Trace Alignment Adiustment in this section. 10. Rotate the GRAT ILLUM control throughout its range and notice that the graticule lines are illuminated as the control is turned clockwise. Set the control so graticule lines are illuminated as desired. Calibration Check 11. Move the trace two divisions beiow graticuie center and reconnect the calibrator signal {io the amplifier plug-in input connector. 12. The display should be four divisions in amplitude with six complete cycles (five complete cycles for 50-hertz line frequency) shown horizontaily. An incorrect display indicates that the oscilipsocpe mainframe or plug-ins need to be recalibrated. Readout 13. Turn the READOUT INTENS control clockwise until an alphanumeric display is visible within the top or bottom division of the cri (reset the FOCUS adjustment if necessary for best definition of the readout). Change the Volts/Div switch of the ampiitier plug-in thatis selected for display. Notice that the readout portion of the display changes as the deflection factor is changed. Likewise, change the Sec/Div switch of the time-base unit that is selected for display. Notice that the readout display for the time-base unit changes also as the sweep rate is changed. Operating information--5440 14. Set the time-base unit for magnified operation. Notice that the readout display changes io indicate the correct magnified sweep rate. If a readout-coded 10X probe is availabie for use with the vertical unit, install iton the input connector of the vertical plug-in. Notice that the deflection factor indicated by the readout is increased by 10 times when the probe is added. Return the time-base unit to normal sweep operation and disconnecithe probe. . 15. Notice that the readout from a particular plug-in occupies a specific location on the display area. Hf either of the vertical plug-in units is a dual-trace unit, notice that the readout for Channel 2 appears within the lower division of the cri below the readout for Channel 1. Beam Finder 16. Move the display off-screen with the vertical position contro. 17. Push the BEAM FINDER button and observe that the display compresses into the screen area. Reposition the display to screen center and release the BEAM FINDER button. External Intensity input 18. Connecta 5 volt, 1 kHz sine-wave Or square-wave signal to the EXT INTENSITY INPUT connector on the rear panel, Also, use the signa! to externaliy trigger the time-base plug-in. 19. Slowly rotate the INTENSITY control counter- clockwise until the trace appears to be a series of dimmed and brightened segments. The brightened segmenis correspond with the tops of the calibrator squarewaves. GENERAL OPERATING INFORMATION Display Focus if a weii-defined display cannot be obtained with the FOCUS control, even at low intensity settings. adjustment of the internal astigmatism control may be required, To check for proper setting of the Astig control, slowly turn the FOCUS control through the optimum setting with a signal displayed on the ¢rt screen. H the Astig control is correctly set, the vertical and horizontal portions of the trace will come into sharpest focus at the same position of the FOCUS control. 1-3 Operating Information—5440 Beam Finder The BEAM FINDER switch provides a means of iocating a display that overscans the viewing area either vertically or horizontally. When the BEAM FINDER switch is pressed, the display is compressed within the graticule area and the display intensity is increased. To locate and reposition an overscanned display, use the following procedure: 1. Press the BEAM FINDER switch, hold it in, then increase the vertical and horizontal deflection factors until the display is within the graticule area. 2. Adjust the vertical and horizontal position controls io center the display about the vertical and horizontal centeriines. 3. Release the BEAM EINDER switch; the display shouid remain within the viewing area. Readout (Works Only With 5400-Series Plug-in Units) The readout system of the power supply/amplifier and display modules aliows alphanumeric display of informa- tion on the crt, along with the analog waveform displays. The information displayed by the readout system is obtained from the plug-in units that are installed in the plug-in compariments. The characters of the readout display are written by the crt beam on à time-shared basis with the signal waveiorms. The Readout System operates in a free-running mode to interrupt the waveform display to present characters. The waveform display is interrupted for only about 20 microseconds for each character that is displayed. The readout information from each piug-in is called a word. Up to six {eight with Option 3) words of readout information can be displayed. The location at which each readout word is presented is fixed and is directly related to the plug-in unit and channel from which it originated. Fig. 1-2 shows the area of the graticule where the readout from each plug-in unit channel is displayed {external readout programming is available only with Option 3). Notice that the readout from Channel 1 of each plug-in unit is displayed within the top division of the graticule and the readout from Channel 2 is displayed directly below within the bottom division of the graticuie. Only the readout from plug-in channels that are selected by display switches, or by the mode switches of dual-channel plug-ins, appear in the readout display. 1-4 The READOUT INTENS control determines the inten- sity of only the readout portion of the display independent of the other traces. The readout system is inoperative in the fully counterciockwise OFF position. This may be desirable when the top and bottom divisions of the graticule are to be used tor waveform display, or when the trace interruptions necessary to display characters do not allow a satisfactory waveform display to be obtained. Option 3, Exiernally Programmed Seventh and Eighth Readout Words This option adds a 25-pin connector to the rear-panei of the 5440 through which two ten-character readout words can be displayed on the crt, see Fig. 1-2. Display Switching Logic The electronic switching for time-shared displays is produced at the plug-in interface within the mainframe; however, the switching logic is selected in the plug-in units. The system allows any combination of plug-ins and Display switch settings. Refer to the individual piug-in manuals for specific capabilities and operating procedures.

REV MAR 1987 NOTE At sweep rates faster than approximately 1 us, the 5810, 5812, and 5B13 Time Base plug-in trigger circuit will not respond fast enough, when used in a 5440, to allow the leading edge of the display to be observed. Differences in wiring between the 5100-series and 5400-series oscilioscope plug-in interfaces will not allow the use of the composite trigger mode of the SEO, 5812, and 5813 Time Base plug-ins when used in the 5440. If the time base units are put in this mode, they will trigger off the left vertical plug-in only. Vertical Plug-in Compartments. When a vertical plug-in is in the active mode (Display button pushed in), a logic level is applied to the switching circuit in the mainframe and a display from this plug-in will occur. When two plug- ins are both active in the vertical compartments, a multi- trace display will occur {Alternate or Chopped). When no plug-in is in the active mode, the signal from the left compartment will be displayed. A time-base unit operated in one of the vertical compartments has a permanent internal connection to apply a logic level to the switching circuit; thus, a vertical trace produced by this unit will always be displayed, Horizontal Plug-In Compartment. Alternate or Chopped display switching is selected ona time-base unit operated in the horizontal compartment. When the Display switch is out (Alt), a negative impulse is supplied at the end of the sweep to allow alternate switching between plug-ins and plug-in channels. When the Display switch is pushed in {Chop), a chopped display will appear if a multi-trace display is required by the plug-ins in the vertical compartments. A vertical plug-in unit operated in the horizontal compartment has a permanent internal connection to provide a chopped display # it is required. Switching Sequence. Four display time slots are provided on a time-sharing basis. When two vertical plug- ins are active. each receives two time siots, so the switching sequence is: left, left, center, center, etc. The two time slots aliotied to each plug-in are divided between amplifier channels in a dual-trace unit; if two dual-trace piug-ins are active, then the switching sequence is: left Channel 1, left Channel! 2, center Channel 1, center Channel 2, etc. 11 only one vertical plug-in is active, it receives all four time slots. The switching sequence is the same for both the Allernate and Chopped display modes. REV MAR 1987 Operating Information—5440 Vertical Display Mode Display On. To display a signal, the Display button of the appiicable vertical plug-in unit must be pushed in to activate the unit. if two plug-ins are installed in the vertical compartments and only the signal from one of the units is wanted, set the Display switch of the unwanted unit to ОН (button out). H neither plug-in is activated, the signal from the left unitis dispiayed. Both plug-ins can be activated for multi-trace displays. Alternate Mode. The alternate position ofthe time-base unit Display switch produces a display that alternates between activated plug-ins and amplifier channels with each sweep of the crt. The switching sequence is describ- ed under Display Switching Logic in this section. Although the Alternate mode can be used at all sweep rates, the Chop mode provides a more satisfactory display at sweep rates from about one millisecond/division 10 five seconds/division. At these slower sweep rates, alternate- mode switching becomes difficult to view. Chopped Mode. The Chop position of the time- base unit Display switch produces a display that is electronicaliy switched between channels at a 100- Kilohertz rate. The switching sequence is discussed earlier. In general, the Chop mode provides the best display at sweep rates slower than about one millisecond/division or whenever dual-trace, single- shot phenomena are to be displayed. At faster sweep rales, the chopped switching becomes apparent an may interfere with the display. | Dual-Sweep Displays. When a dual-sweep time-base unit is operated in the horizontal compartment, the alternate and chopped time-shared switching for either the A or B sweep is identical to that for a single time-base unit. However, if both the A and B sweeps are operating, the 5440 operates in the independent pairs mode. Under this condition, the left vertical unit is always displayed at the sweep rate of the A time base and the right vertical unit is displayed at the sweep rate of the B time-base (non- delayed sweep only). This results in two displays that have compietely independent vertical deflection and chopped or alternate sweep switching. X-Y Operation In some applications, it is desirable to display one signal versus another (X-Y) rather than against an internal sweep. The flexibility of the plug-in units available for use with the 5440 provides a means for applying a signal to the horizontal deflection system for this type of display. Some of the 5B-series time-base units can be operated as amplifiers, in addition to their norma! use as time-base generators. 1-5 Operating Information--5440 Raster Display A raster-type display can be used to effectively increase the apparent sweep length, For this type of display, the trace is defiected both vertically and horizontally by sawtooth signals, and is accomplished by installing a 58- series time-base unit in the left vertical compartment, as well as one in the horizontal compartment. Normally, the unit in the vertical compartment shouid be set to a siower sweep rate than the one in the horizontal compartment; the number of horizontal traces in the raster depends upon the ratio between the two sweep rates. Information canbe displayed on the raster using the Ext Intensity Input to provide intensity modulation of the display. This type of raster display can be used to provide a television-type display. Intensity Modulation Intensity {Z-Axis) modulation can be used to relate a third item of electrical phenomena to the vertical (Y-Axis) and the horizontal {(X-Axis) coordinates without affecting the waveshape of the displayed signal. The Z-Axis modulating signal, applied to the EXT INTENSITY INPUT, changes the intensity of the displayed waveform to provide this type of display. The voltage amplitude required for visible trace modulation depends on the setting of the INTENSITY control. About +5 volts will turn on the display to a normal brightness level! from an off level, and about —5 volts will turn the display off from a noymal brightness level. "Gray scale” intensity moduta- tion can be obtained by applying signals between these levels. Maximum safe input voltage is +50 volts, Usable frequency range of the Z-Axis circuit is de to two megahertz. Time markers applied to the EXT INTENSITY INPUT provide a direct time reference on the display. With uncalibrated horizontal sweep or X-Y operation, the time marxers provide a means of reading time directly from the display. However, if the markers are not time-related to the displayed waveform, a single-sweep display should be used {for internal sweep only} to provide a stable display. Calibrator The internal calibrator of the 5440 provides a con- venient signal source for checking basic vertical gain and sweep ming. The calibrator signal is also very useful for adjusting probe compensation, as described in the probe instruction manual. The output square-wave voltage is 400 millivolts, within 1%, and the sguare-wave current is 4 milliamperes, within 1%. The frequency of the square- wave signal is twice the power-line frequency. The signal is obtained by clipping the probe to the loop. 1-6 Display Photography A permanent record of the crt display can be obtained — with an oscilloscope camera system. The crt bezel of the 5440 provides integral mounting for a Tektronix os- cilioscope camera, The instruction manuals for the Tektronix oscilloscope cameras include complete instruc- tions for obtaining waveform photographs. OPERATING VOLTAGE ca UTION PO S This instrument is designed for operation from a power source with its neutral at or near earth (ground) potential, and with a separate safety-earth conductor. It is not intended for operation from two phases of a multi-phase system, or across the legs of a single-phase, three-wire system. INSTRUMENT CONVERSION The 5440 Power Supply/Amplifier module and the display module can be fastened together stacked or side by side; this permits operation as a bench oscilloscope, orin a stan- dard 19-inch rack. The two modules can quickly be convert- ed from a bench model to a rackmount model, or vice versa. Field conversion kits, including the necessary parts, and instructions are available and can be installed at a later time. See your Tektronix Catalog or contact your Tektronix field office. | NOTE Before attempiing to operate the instrument, make sure the module wiring interconnections are correct. RACKMOUNTING The rackmount version of the 5400-series oscilloscope is designed for operation in a standard 19-inch wide rack that has Universal, IA, RETMA, or Western Electric hole spac- ing. When properly mounted, this instrument will meet all electrical and environmental specifications given in Section 2. REY MAR 1687 Mounting Method This instrument will fit most 18-inch wide racks whose front and rear holes conform to Universal hole spacing, some drilling may be required on racks having EIA, RETMA, or Western Electric hole spacing. The slide-out tracks easily mount to the cabinet rack front and rear vertical mounting rails if the inside distance between the front and rear rails is within 10-8/16 inches to 24-3/8 inches. If the inside distance exceeds 24-3/8 inches, some means of support is required for the rear ends of the slide-out tracks. (For example, make extensions for the rear mounting brackets.) Rack Dimensions Height. At least 5-1/4 inches of vertical space is required to Mount this instrument in a rack. if other instruments are operated in the rack, an additional 1/4 inch is required, both above and below the oscilloscope, to allow space for proper circulation of cooling air. Width, A standard 18-inch wide rack may be used. The dimension of opening between the front rails must be at least 17-5/8 inches for a cabinet in which the front lip of the stationary section is mounted behind an untapped front rail as shown in Fig. 1-4A. If the front rails are tapped, and the stationary section is mounted in front of the front rail as shown in Fig. 1-4B, the dimension between the front rails should be at least 17-3/4 inches. These dimensions allow room on each side of the instrument for the slide-out tracks 10 operate so the instrument can move freely in and out of the rack. Depth. For proper circulation of cooling air, allow at least two inches clearance behind the rear of the instrument and any enclosure on the rack. if it is sometimes necessary or desirable to operate the oscilloscope in the fully extended position, use cables that are long enough to reach from the signal source to the instrument. | WARNING | During rackmount installation, interchanging the left and right slide-out track assemblies defeats the exten- sion stop (safety latch) feature of the tracks, Equip- ment could, when extended, come out of the slides and fall from the rack, possibly causing personal injury and equipment damage. REY MAR 1987 Operating information -— 5440 When mounting the supplied slide-out tracks, inspect both assemblies to find the LH (left hand) and RH {right hand) designations to determine correct place- ment. Install the LH assembly to your left side as you face the front of the rack and install the RH assembly to your right side. Refer to the rackmounting instruc- tions in this manual for complete information. Lie, Installing The Slide-Out Tracks The slide-out tracks for the instrument consist of two assemblies, one for the left side of the instrument and one for the right side. Each assembly consists of three sections. A stationary section attaches to the front and rear rails of the rack, the chassis section attaches to the instrument (and is installed at the factory), and the intermediate section fits between the other two sections to allow the instrument to fully extend out of the rack. The small hardware components included with the slide- out track assemblies are used to mount the tracks to most standard 18-inch rack rails having this compatibility. NOTE 1. Front and rear rail holes must be large enough to allow inserting a 10-32 screw through the rail mount- ing hole if the rails are untapped (see Fig. 1-4A). 2. Or, front and rear rail holes must be tapped to ac- cept a 10-32 screw if Fig. 1-4B mounting method is used. Note in Fig. 1-4B right illustration that a No. 10 washer (not supplied) may be added to provide in- creased bearing surface for the slide-out track station. ary section front flange. Because of the above compatibility, there will be some small parts left over. The stationary and intermediate sec- tions jor both sides of the rack are shipped as a matched set and should not be separated. The matched sets of both sides including hardware are marked 351-0195-00 on the package. To identify the assemblies, note that the automat- ic latch and intermediate section stop is located near the top of the matched set. Mounting Procedure. Use the following procedure to mount both sides. See Fig. 1-4 for installation details. 1-7 Operating information—5440 1. To mount the instrument directiy above or below another instrument in a cabinet rack, select the ap- propriate holes in the front rack rails for the stationary sections, using Fig. 1-5 as a guide. 2. Mount the stationary slide-out track sections to the front rack rails using either of these methods: {a} Hthe front flanges of the stationary sections are to be mounted behind the front raiis (rails are counter- sunk or not tapped}. mount the stationary sections as shown in Fig. 1-4A right illustration. {b} HH the front flanges of the stationary sections are to be mounted in front of the front rails (rails are tapped for 10-32 screws), mount the stationary sections as shown in Fig. 1-4B right illustration. To provide in- creased bearing surface for the screw head to securely fasten the front flange to the rail, a flat washer (not supplied) may be added under the screw head. However, if this mounting method is used, the front panel will not fit flush against the front rail because of the stationary section and washer thickness. if a flush fit is preferred, method 2 (a) should be used.

Mount the stationary slide-out sections to the rear rack rails using either of these methods. (a) If the rear rack rail holes are not tapped to accept 10-32 machine screws, mount the left stationary sec- tion with hardware provided as shown in the left or center illustration of Fig. 1-4A. Note that the rear mounting bracket can be installed either way so the siide-Qut tracks will fit a deep or shallow cabinet rack. Use Fig. 1-4A as a guide for mounting the right stationary section. Make sure that the stationary sec- tions are horizontally aligned so they are level and parallel with each other. (b) 1f the rear rack rail holes are tapped to accept 10-32 machine screws, mount the left stationary sec- tion with hardware provided as shown in the left or center illustration of Fig. 1-4B. Note that the rear mounting bracket can be installed either way so the slide-out tracks will {it a deep or shailow ¢abinet rack. Use Fig. 1-48 as a guide for mounting the right stationary section. Make sure the stationary sections are horizontally aligned so they are level and parallel with each other. Installation And Adjustment To insert the instrument into the rack, proceed as follows: 1. Pull the slide-out track intermediate sections out to the fully extended position. 2. Insert the instrument chassis sections into the intermediate sections. 3. Press the stop latches on the chassis sections and push the instrument toward the rack until the tatches snap into their holes. 4. Again press the stop latches and push the instru- ment into the rack. To adjust the slide-out tracks for smooth stiding action, loosen the screws used to join the stationary sections 10 the rails of the rack. Center the instrument, allowing the slide-out tracks to seek the proper width, then tighten the screws. To secure the instrument front-panel to the rack, the rack must either have universal hole spacing, or a hole must be dritled and tapped fora 10-32 screw, see Fig. 1-5. Using the hardware (not furnished) indicated in Fig. 1-5, secure the R5440 to the front rails of the rack. 1-10 Slide-Out Track Maintenance The slide-out tracks require no lubrication. The special | dark gray finish on the sliding parts is a permanent lubrication, OPERATING TEMPERATURE The 5440 can be operated where the ambient air temperature is between 0% C and +50%C, The instrument can be stored inambient temperature between —40°C and +70°C, After storage at a temperature beyond the Operating limits, allow the chassis temperature to come within the operating limits before power is applied. A thermal cutout in the display module provides thermal protection and disconnects the power to the instrument if the internal temperature exceeds a safe operating level. This device will automatically re-apply power when the temperature returns to a safe level. PLUG-IN UNITS The 5440 is designed to accept up to three Tektronix 5000-series plug-in units. (Only the p:ug-in units without an N suffix will provide display readout} This plug-in feature allows a variety of display combinations and also allows selection of bandwidth, sensitivity, display mode, и etc., to meet the measurement requirements. in addition, it allows the oscilioscope system 10 be expanded to meet future measurement requirements. The overall capabilities of the resultant system are in large part determined by the characteristics of the plug-ins selected. installation To install a plug-in unit into one of the plug-in compariments, align the slots in the top and bottom ofthe piug-in with the associated guides in the plug-in compart- ment. Push the plug-in unit firmiy into the plug-in compartment until it locks into place. To remove a plug-in, pull the release latch on the plug-in unit to disengage it and pull the unit out of the plug-in compartment. Plug-in units can be removed or instalied without turning off the instrument power. It is not necessary that all of the plug-in compartments be filled to operate the instrument, the only plug-ins needed are those required for the measurement to be made. When the display unit is adjusted in accordance with the adjustment procedure given in the display unit instruc- tion manual, the vertical and horizontal gain are standar- dized. This allows adjusted plug-in units to be changed from one plug-in compartment to another without read- justment. However, the basic adjustment of the individual piug-in units shouid be checked when they are installed in this system to verify their measurement accuracy. See the service information section of the plug-in unit manual for verification procedure. REY MAR 1987 Мен” Selection The plug-in versatility of the 5400-series oscilloscope altows a variety of display modes with many different piug- ins. The following information is provided here to aid in plug-in selection. To produce a single-trace display, install a single- channel vertical unit (or dual-channel unit set for single- channel operation) in either of the vertical (left or center) compartiments and a time-base unit in the horizontal (right) compartment. Fordual-trace displays, either install a dual-channel vertical unit in one of the vertical com- partments or install a single-channet vertical unit in each vertical compartment. A combination of a single-channel and a dual-channel vertical unit allows a three-trace display. likewise, a combination of two dual-channel vertical units allows a four-trace display. To obtain a vertical sweep with the input signal displayed horizontally, insert the time-base unit into one of the vertical compartments and the amplifier unit in the horizontal compartment. If a vertical sweep is used, there Is no retrace blanking and the time-base unit triggering must be accomplished externally. For X-Y displays, either a 5A-series amplifier unit or a 5B-series time-base unit having an amplifier channel can “be instatied in the horizontal compartment to acceptthe X signal. The Y signal is connected to a 5A-series amplifier unit installed in a vertical compartment. Special purpose plug-in units may have specific restric- tions regarding the compartments in which they can be instalied. This information will be given in the instruction manuais for these plug-ins. BASIC OSCILLOSCOPE APPLICATIONS The 5400-series oscilloscope and its associated plug-in units provide a very flexible measurement system. The capabilities of the overall system depend mainly upon the plug-ins that are chosen. The following information describes the techniques for making basic measurements. These applications are not described in detail, since each application must be adapted to the requirements of the individual measurement. Specific applications for the individual plug-in units are described in the manuals for these units, Contact your focal Tektronix Field Office or representative for additional assistance, REY MAR 1987 Operating Information—5440 Peak-to-Peak Voltage Measurements--AC To make peak-to-peak voltage measurements, use the following procedure: 1. Set the input coupling on the vertical plug-in unit to Gnd and connect the signal to the input connector. 2. Set the input coupling to ac and set the Volts/Div switch to display about 5 or 6 vertical divisions of the waveform, Check that the variable Volts/Div control (red knob} is in the Cal position. 3. Adjust the time-base triggering controls for a stable display and set the Sec/Div switch to display several cycles of the waveform. 4. Turn the vertical Position control so that the lower portion of the waveform coincides with one of the graticule lines below the center horizontal line, and the top of the waveform is in the viewing area. Move the display with the horizontal Position control so that one of the upper peaks is aligned with the center vertical reference line (see Fig. 1-6). 5. Measure the vertical deflection from peak to peak (divisions). NOTE This technique may also be used to make measurements between two points on the waveform, rather than peak to peak, 5. Muitipty the distance (in divisions) measured instep 5 by the Volts/Div switch setting. Also include the atienuation factor of the probe, if applicable. EXAMPLE: Assume a peak-to-peak vertical deflection of 4.6 divisions and a Voits/Div switch settings of 5 Y, Peak-to-peak _ 4.6 5 (Voits/Div _ 23 voits {divisions) setting} volts 1-41 Operating Information-—5440 NOTE If an attenuator probe is used that cannot change the scale factor readout {(Volts/Div), multiply the right side of the above equation by the attenuation factor. Position to renter vertical line Vertical deflection Fig. 1-6. Measuring peak-to-peak voliage of a waveform. Instantaneous Voltage Measurementi—DC To measure the dc level at a given point on a waveform, use the following procedure: 1. Set the input coupling of the vertical plug-in unit to Gnd and position the trace to the bottom fine of the graticule (or other selected reference line). If the voltage to be measured is negative with respect to ground, position the trace to the top line of the graticule. Do not move the vertical Position control after this reference has been established. NOTE To measure a voltage leve! with respec! to a voltage other than ground, make the following changes to step 1: Set the input coupling switch to dc and apply the reference voltage to the input connector, then position the trace to the reference fine. 1-12 2. Connect the signal to the input connector. Set the — input coupling to dc (the ground reference can be checkedatany time by setting the input coupling to Gnd). 3. Set the Voits/Div switch to dispiay about 5 or 6 vertical divisions of the waveform. Check that the variable Volis/Div control (red knob) is in the Cal position. Adjust the time-base triggering controls for a stable display. 4. Measure the distance in divisions between the reference line and the point on the waveform at which the de leve! is to be measured. For example, in Fig. 1-7 the measurement is made between the reference line and point À. 5. Establish the polarity. The voltage is positive if the signal is applied to the + input connectar and the waveform is above the reference line. 6. Multipiy the distance measured in step 4 by the Volts/Div switch setting. Include the attenuation factor of the prope, if applicable (see the note following the Peak- to-Peak Voltage Measurement example). EXAMPLE: Assume that the vertical distance measured is 4.6 divisions, the polarity is positive, and the Volts/Div Switch setting is 2 Y, +92 volts instantaneous _ 4.6 2 _ Voltage (divisions) (Yolts/Div) Vertical {A} distance Reference line Fig. 1-7. Measuring instantaneous de voltage with respect to a „°° reference voltage, REV MAR 1987 Comparison Measurements In some applications, it may be necessary to establish a set of deflection factors other than those indicated by the Volts/Div or Sec/Div switches. This is useful for com- paring signais to a reference voltage amplitude or period. To establish a new set of deflection factors based upon a specific reference amplitude or period, proceed as follows: Vertical Deflection Factor 1. Apply a reference signal of known amplitude to the vertical input connector. Using the Voits/Div switch and variable Volts/Div control, adjust the display for an exact number of divisions. Do not move the variable Voits/Div controi after obtaining the desired defiection. 2. Divide the amplitude of the reference signal {voits) by the product of the deflection in divisions {established in step 1) and the Volts/Div switch setting. This is the Deflection Conversion Factor. Deflection reference signa! amplitude (voits) Conversion = Factor deflection X Volts/Div (divisions) setting 3. Todetermine the peak-to-peak amplitude of a signal compared to a reference, disconnect the reference and apply the signal to the input connector, 4. Set the Volts/Div switch to a setting that provides sufficient defiection to make the measurement. Do not readiust the variable Volis/Div control. 5. To establish a Modified Deflection Factor at any setting of the Voits/Div switch, multiply the Volts/Div switch setting by the Deflection Conversion Factor es- tablished in step 2. Modified , Deflection | Volts/Div . Deflection = settin X Converstion Factor 9 Factor O. Measure the vertical deflection in divisions and determine the amplitude by the foliowing formula: Modified Signal | Deflection Deflection X нЕ . Amplitude {divisions) Factor REY MAR 1987 Operating Information—5440 EXAMPLE: Assume a reference signal amplitude of 30 volts, a Voits/Div switch setting of 5 V and a deflection of four divisions. Substituting these values in the Deflection Conversion Factor formula (step 2): 30 V ce == 1.5 (4) (5 Y) Then, with a Volts/Div switch setting of 2 V, the Modified Deflection Factor {step 5) is: (2 V) (1.5) = 3 volts/division To determine the peak-to-peak amplitude of an applied signal that produces a vertical deflection of five divisions with the above conditions, use the Signal Amplitude formula (step 6): {3 V} (5) = 15 volts Sweep Rate 1. Apply a reference signal of known freguency to the vertical input connector. Using the Sec/Div switch and variable Sec/Div control, adjust the display so that one cycle of the signal covers an exact number of horizontai divisions. Do not change the variabie Sec/Div controi after obtaining the desired deflection. - 2. Divide the period of the reference signal (seconds) by the product of the horizontal deflection in divisions {established in step 1) and the setting of the Sec/Div switch, This is the Deflection Conversion Factor. Deflection reference signal period (seconds) Conversion = Factor horizontal Sec/Div deflection X switch (divisions) setting 3. To determine the period of an unknown signal, disconnect the reference and apply the unknown signal. 4. Set the Sec/Div switch to a setting that provides sufficient horizontal deflection to make an accurate measurement. Do not readjust the variable Sec/Div con- trot. 5. To establish a Modified Deflection Factor at any setting of the Sec/Div switch, muitipiy the Sec/Div switch setting by the Deflection Conversion Factor established in step 2. Modified Detfiection Sec/Div Deflection = switching settin X Conversion Factor 9 9 Factor 1-13 Operating Information—=5440 6. Measure the horizontal defiection in divisions and determine the period by the following formula: Modified horizontal Period == Defiection X defiection Factor {divisions} EXAMPLE: Assume a reference signal frequency of 455 nertz (period 2.2 milliseconds), a Sec/Div switch setting of 2 ms, and a horizontal deflection of eight divisions. Substituting these values in the Deflection Conversion Factor formula (step 2}: 2.2 ms (8) (02ms) 1*7 Then, with a Sec/Div switch setting of 50 us, the Modified Defiection Factor (step 5) is: {50 us) (1.375) = 68.75 microseconas/division To determine the time period of an applied signal which compietes one cycie in seven horizontal divisions, use the Period formula (step 6): (68.75 us) (7) = 481 microseconds This product can be converted to frequency by taking the reciprocal of the period (see application of Deter- mining Frequency). Time Period Measurement Te measure the time (period) between two points ana waveform, use the foliowing procedure: 1. Connect the signal to the vertical input connector, select either ac or de input coupling, and set the Voits/Div switch to display about four divisions of the waveform. 2. Set the time-base triggering controls to obtain a Stable display, Set the Sec/Div switch to the fastest sweep rate that will permit displaying one cycle of the waveform in ess than eight divisions (some non-linearity may occur in tne first and (ast graticute divisions of display}. Refer to Fig. 1-8, 3. Adjust the vertical Position control to move the points between which the time measurement is made to the center horizontal line. Adjust the horizontal Position control to center the time-measurement points within the center eight divisions of the graticule. 1-14 4. Measure the horizontal distance between the time measurement points. Be sure the variable Sec/Div control is in the Cal position, 5. Multiply the distance measured in step 4 by the setting of the Sec/Div switch, EXAMPLE: Assume that the horizontal distance between the time-measurement points is five divisions and the Sec/Div switch is set to .1 ms. Using the formula: horizontal Sec/Div Period = distance X switch = (5) (0.1 ms) = 0.5 ms (divisions) setting The period is 0.5 millisecond. Determining Frequency The time measurement technique can also be used to determine the frequency of a signal. The frequency of a periodically recurrent signal is the reciprocal of the time duration (period) of one cycie. Use the foliowing procedure: 1. Measure the period of one cycte of the waveform as described in the previous application. 2. Take the reciprocal of the period to determine the frequency. EXAMPLE: The frequency of the signal shown in Fig. 1- 8. which has a period of 0.5 millisecond is: 1 Frequency = = = 2 kitohertz period 0.5 ms : ; i ado 3 4 | Horizontal ; | distance | Fig. 1-8. Measuring time duration {period} between points on a waveform, REV MAR 1987 pee Risetime Measurement Risetime measurements employ basically the same techniques as the time-period measurements. The main difference is the points between which the measurement is made. The following procedure gives the basic method of measuring risetime between the 10% and 90% points of the waveform. 1. Connect the signal to the input connector. 2. Set the Volts/Div switch and variable Volts/Div control to produce a display exactly five divisions in amplitude. 3. Center the display about the center horizontal line with the vertical Position control. 4. Set the time-base triggering controls to obtain a stable display. Set the Sec/Div switch to the fastest sweep rate that will display less than eight divisions between the 10% and 90% points on the waveform (see Fig. 1-8). 5. Adjust the horizontal Position control to move the 10% point of the waveform to the second vertical line of the graticule. 6. Measure the horizontal distance between the 10% and 80% points. Be sure the variable Sec/Div control is in the Cal position. 7. Multiply the distance measured in step 6 by the setting of the Sec/Div switch. 10% :....] se … Point Horizontal distance Fig, 1-9. Measuring risetime. REV MAR 1987 Operating Information—5440 EXAMPLE: Assume that the horizontal distance between the 10% and 80% points is four divisions and the Sec/Div Switch is set to | us. Using the period formula to find risetime: Risetime horizontal Sec/Div . = distance X switch = (4) {1 us) = 4 us period 10 (divisions) setting The risetime is 4 microseconds. Time Difference Measurements When used in conjuction with a calibrated time-base plug-in unit, the multi-trace feature of the 5400-series oscilloscope permits measurement of time difference between two or more separate events. To measure time difference, use the following procedure: 1. Set the input coupling switches of the amplifier channels to either ac or dc. 2. Setthe Display switch on the time-base unit to either Chop or Alt. In general, Chop is more suitable for low- frequency signals. More information on determining the mode is given under Vertical Display Mode in this section. 3, Set the vertical plug-intriggering switches to trigger the display on Channel 1 (or left plug-in} only. 4. Connect the reference signal to the Channel 1 input connector and the comparison signal to the Channel 2 {or center plug-in} input connector. The reference signal should preceded the comparison signal in time. Use coaxial cables ог probes which have similar time-delay characteristics to connect the signal to the input connec- tors. 5. If the signals are of opposite polarity, invert the Channel 2 {or center plug-in) display. {Signals may be of opposite polarity due to 180% phase difference; if so, take this into account in the final calculation.) 6. Set the Volts/Div switches to produce about four divisions of display waveform. 7. Set the time-base triggering controls for a stable display. Set the Sec/Div switch for a sweep rate which shows three or more divisions between the measurement points, if possible. 8. Adjust the vertical Position controls to bring the measurement points to the center horizontal reference line. 1-15 Operating Information-—5440 9. Adjust the horizontal Position controi so the Channei 1 (or left plug-in) waveform (reference) crosses the center horizontal line at a vertical graticule line. 10. Measure the horizontal distance between the wo measurement points (see Fig. 1-10). 11, Muitiply the measured distance by the setting of the Sec/Div switch. EXAMPLE: Assume that the Sec/Div switch is set to 50 us and the horizontal distance between measurement points is four divisions. Using the formula: Time Sec/Div horizontal = switch X distance = (50 us) (4) — 200 us Dela Co setting (divisions) The time delay is 200 microseconds, Channel 2, or center plug-in Channel 1, or left plug-in {reference} 50% Amplitude ВУ! Horizontal distance Fig. 1-10. Measuring time difference between two puises. Multi-trace Phase Difference Measurement Phase comparison between two or more signals of the same frequency can be made using a dual-trace piug-in or two single-trace plug-ins. This method of phase difference measurement can be used up to the frequency limit of the vertical system. To make the comparison, use the foliow- ing procedure: 1. Set the input coupling switches of the amplifier channels to either ac or dc. 2. Setthe Display switch on the time-Ddase unit to either Спор ог АН. In general, Chop is more suitable for low- frequency signals and the Alt position is more suitable for high-frequency signals. More information on determining the mode is given under Vertical Display Mode in this section, 1-16 3. Set the vertical plug-in triggering switches to trigger the display on Channel 1 {or left piug-in) only. 4. Connect the reference signal to the Channel 1 input connector and comparison signal to the Channel 2 (or center piug-in) input connector. The reference signal should precede the comparison signalin time. Use coaxial cables or probes which have similar time-delay characteristics to connect the signals tothe input connec- tors. 5. li the signals are of opposite polarity invert the Channel 2 (or center plug-in} display. (Signals may be of opposite polarity due to 180° phase difference; if 50, take this into account in the final calculation.) 6. Set the Voits/Div switches and the variable Voits/Div controls so the displays are equal and about five divisions in amplitude. 7. Set the time-base triggering controls to obtain a stable display. Set the Sec/Div switch to a sweep rate which displays about one ¢cycie of the waveform, 8. Move the waveforms to the center of the graticule with the vertical Position controls. 9. Turn the variable Sec/Div contro! until one cycie of the reference signal (Channel 1, or left plug-in) occupies exactly eight divisions between the second and tenth vertical lines of the graticule {see Fig. 1-11). Each division of the graticuie represents 45° of the cycle {360° + 8 divisions =45° /division}, The sweep rate can be stated in terms of degrees as 45°/division.

Multiply the measured distance (in divisions) by 45° /dwvision {sweep rate) to obtain the exact amount of phase difference. EXAMPLE: Assume a horizontal difference of 0.6 division with a sweep rate of 45° /division as shown in Fig. 1-11. Use the formula: Phase horizontal sweep rate Difference = difference X (degrees/ — (0.6) (45°) = 27° (divisions) division) The phase difference is 27°. High Resolution Phase Measurement More accurate dual-trace phase measurements can be made by increasing the sweep rate {without changing the “variable Sec/Div control setting). One of the easiest ways to increase the sweep rate is with the Swp Mag {10X) — button on the time-base unit. The magnified sweep rate is automatically indicated by the crt readout and knob-skirt scale-factor readout. REV MAR 1987 Operating information—5440 EXAMPLE: If the sweep rate were increased 10 times with the magnifier, the magnifier sweep rate shouid be 45°/division + 10 = 4.5% /division. Fig. 1-12 shows the same signals as used in Fig. 1-11, but with the Swp Mag button pushed in.
