TECHNICAL INFORMATION

DETECTORS FOR USE WITH WAVETEK MICROWAVE, INC. (WMI) SCALAR ANALYZERS

AND MODEL 1045 AND 1034A POWER METERS

The purpose of this Technical Information sheet is to define parameters and specifications perti­ nent to all of the detachable detector options available for the various WMI scalar analyzer systems and the Model 1045 and 1034A power meters. Parameters common to each of the detector configurations are defined first, and then individual detector specifications are given.

WMI offers three different types of detectors for the above scalar systems and power meters.

These include the single diode and balanced

(dual diode) coaxial detectors, and the balanced element waveguide detector. The single diode and balanced coaxial detectors ha ve a maximum power rating of 200mW (+23dBm), and cover the frequency range of I MHz to 18.5GHz or I MHz to

26.5GHz. One version of the single diode detector

(used with the Model 1045 Power Meter) has a built-in atlenuator to allow it to measure maxi­ mum power levels up to lOW (+40dBm) CW or up to 200W (+53dBm) peak. The balanced element waveguide detector has a maximum power rating of loomW (+dBm), and is designed for the frequency range from 26.5GHz to

4O.0GHz.

Coaxial detectors are available with type N,

APC7, and APC3.5 (compatible with SMA) connectors, and the waveguide detector comes with a WR28 waveguide (UG-599/U

Flange).

Frequencies down to 100kHz are available on special order, and various types of 50 to 75 ohm adapters are available for the coaxial detectors.

HOTH: If it is desired to check the detector/ instrument system performance, refer to the

Performance Verification Test in the Operat­

ing and Maintenance Manual for the particu­ lar instrument.

SINGLE DIODE DETECTOR FEATURES

AND SPECIFICAnONS

Further features and specifications for the WMI single diode detector include the following: o 70dB Dynamic Range o Temperature Compensated o Linearity Compensated o Frequency Response Curve Da ta

Accuracy: The uncertainty of cali­ bration for the single diode <Ietector at ImW (OdBm) is 3% to 18GHz and

5% to 26.5GHz o Flatness: The maximum total varia­ tion of flatness for the single diode detector WIll be between IdB and

4dB from I MHz to 26.5GHz, depend­ ing on the detector model and in­ strument with which it is used. (See the reverse side of this sheet.) o Return Loss: Return loss of the single diode detector is 25dB from

(MHz to 2GHz and 20dB from 2GHz to 12.4GHz with any connector.

With type N or APC7 connectors, return loss is 18dB from 12.4 to

18GHz and 14dB between 18 and

18.5GHz. When detectors with

APC3.5 connectors are used, return loss is 16dB from 12.4 to 18GHz and

14dB to 26.5GHz. o Measurement Accuracy: Figures 6 and 7 show the measurement accura­ cy for the single diode detectors used with the power meters. Single dIode detectors specified for the

1038-H/V system have a measure­ ment accuracy of O.ldB/lOdB plus

O.5dB at -50dBm

DETECTOR HANDLING PRECAUTIONS

Any RF detector is, of necessity, a very delicate instrument and must always be handled with care. Care must be taken to avoid el<ceedlng the detector's electrical rating through static electricity, power input greater than specified, or use of measuring equipment.

Also avoid mechanical stress that could be caused by dropping or over-torquing the detector. See the Operating and Maintenance Manual for the appropriate instrument with which the detector is to be used for further details.

TECHNICAL INFORMATION

DETECTOR ELEMENT AND TRACKING RESISTOR REPLACEMENT PROCEDURES FOR

DETECTORS USED WITH THE 1038-H/V SYSTEM (PIN'S 13782, 13783, 13784, 15272); THE

MODEL 1045 POWER METER (PIN'S 13785, 13786, 13787, 13838, 13840, 14139, 15271); AND THE

MODEL 1034A POWER METER (PIN'S 13779, 13780, 13781)

All of the detector part numbers listed in this Technical

I nformation Sheet represent single diode detectors. I n the single diode detector, the detector element is replaced at the detector end of the cable and the tracking resistor is replaced at the instrument input end of the detector cable.

WARNING: Dimensional tolerances of the detectors are critical. Care must be taken to keep the work area very clean when performing a diode and resistor

changeout so that dirt and dust cannot get into the detector.

Before starting any of these replacement procedures, be sure to read all of the Handling Precautions shown inside the box at the bottom of this page.

4. Late model detectors have only the detector element; no spacer, washer, or ring. If you r detector has no spacer, washer, or ring, then discard the ring from the kit and replace just the element as shown in Figure 1. Make sure that components are correctly seated and pressed firmly into the detector.

WARNING. Use care when pressing the detector element into the housing to avoid damaging the female socket contacts.

5. Replace the cap assembly onto the detector housing assembly, and tighten to 30 inch-pounds (4.4 N-M).

Reassemble the insulator and knurled nut onto the detector.

FOR DETECTOR PIN'S 13779, 13780, 13781, 13782,

13783, 13784, AND 15272 (1038-H/V SYSTEM AND

MODEL 1034A) USE THE FOLLOWING PROCEDURES:

1. Using Figure 1 on page 3 of this sheet as a guide, remove the knurled nut that secures the insulator to the detector. Slide the insulator back along the cable to expose the metal detector body.

2. Unscrew the cap assembly from the detector housing assembly.

3. Remove the detector element and, if included, the ring from the detector housing assembly. (Older detectors may have a capsule spacer and capacitive washer.

Remove these. They will be replaced by the ring included in the kit. If your detector has just the ring, replace it with the ring from the kit.)

Steps 6 through 11 apply only to PIN'S 13779, 13780, 13781

6. Using Figure 2 as a guide, unscrew the strain relief from the connector body.

7. Remove the shrink sleeving from the existing resistor in the detector and check its value against the value of the resistor included in the kit. If they are the same value, leave the existing resistor re-cover it with shrink sleeving).

8. If the resistor values are different, unsolder the existing resistor and replace it with the new resistor from the kit at the same point (pins 3 and 4). Be sure to place shrink sleeving over the new resistor before reassembling.

9. Reassemble by reversing the above steps.

HANDLING PRECAUTIONS

1. GENERAL

Avoid unnecessary handling of the detector element used in the RF detector.

A. Static electricity builds up on a person, especially on dry days, and must never be allowed to discharge through the RF detector. Avoid any exposed leads on the detector input or output.

B. Before installing the detector element in the detector housing, touch the exposed metal housing with your hand to discharge stallC electricity. Then

Install the element into the housing.

C. Before handing a detector element to another person. touch hands first to remove the static electricity potential between you.

D. Do not use an ohmmeter to measure the detector element's diode resistance. The ohmmeter's open circuit voltage or short circuit current could easily damage the diode.

2. MECHANICAL PRECAUTIONS

The RF detector is a very delicate instrument that can be easily damaged during handling. Possible excessive return loss or mechanical breakage can occur. To aVOid problems while installing the detector element, review the procedures detailed in the diode replacement section of this Technical lnlormation sheet. The following precautions are prOVided as supplemental information and are general

In nature.

A. During disassembly of the detector assembly, note the position and alignment of all componeflts.

If small components are damaged. replace them before reassembly.

B. Ensure that all parts are clean. but use extreme care in cleaning them to avoid causing other prOblems. If a cleaning solution must be used, use only ISOPROPYL ALCOHOL, as other solvents can affect the materials used in the detector assembly.

C. Reassemble the assembly using minimum force.

Normally, the assembly can be HAND-TIGHTENED to the point that no space is left between the. housing and the cap. If you can no longer tighten it and any space remains, something may be misaligned internally.

D. Seat the assembly firmly using a torque wrench and the specified torque of 30 inch-pounds (4.4

N-M). ensuring that the wrenches are properly seated on the flat surfaces provided.

1499-16709/2-88/500

From the library of WØMTU

10. Remove the old calibration label since its data will no longer apply. Leave the old part number label on the detector.

11. Check the detector in accordance with the Detector

Performance Evaluation Procedure shown at the bottom of the next column.

12. If facilities are available for evaluating frequency response characteristics, the new calibration data can be marked on the new label, if supplied, or recorded for reference. If a new label is marked, it should be affixed to the detector insulator to replace the old label. If no facilities are available to check frequency response, the detector can be returned to the factory for calibration.

10. Using the #2 screw, secure the thermistor mount to the cap. Then screw the coupling nut back onto the cap.

11. Replace the coupling nut/cap assembly onto the detector housing and tighten it to 30 inch-pounds

(4.4 N-M).

12. Replace the insulator and secure it with the two #2-56 screws.

13. Remove the old calibration label since its data will no longer apply. Leave the old part number label on the detector.

14. Check the detector in accordance with the Detector

Performance Evaluation Procedure given below.

15. If facilities are available for evaluating frequency response characteristics, the new calibration data can be marked on the new label, if supplied, or recorded for reference. If a new label is marked, it should be affixed to the detector insulator to replace the old label. If no facilities are available to check frequency response, the detector can be returned to the factory for calibration.

FOR DETECTOR PIN'S 13785, 13786, 13787, 13838,

13840, 14139, AND 15271 (MODEL 1045) USE THE

FOLLOWING PROCEDURES:

1. Using Figure 3 on page 3 of this sheet as a guide, remove the two #2-56 screws from the sides of the insulator. Slide the insulator back.

2. Unscrew the cap assembly from the detector housing assembly.

3. Remove the detector element and, if included, the ring from the detector housing assembly. (Older detectors may have a capsule spacer and capacitive washer.

Remove these. They will be replaced by the ring included in the kit. If your detector has just the ring, replace it with the ring from the kit.)

4. Late model detectors have only the detector element; no spacer, washer, or ring. If your detector has no spacer, washer, or ring, then discard the ring from the kit and replace just the element as shown in Figure 3. Make sure that the components are correctly seated and pressed firmly into the detector.

WARNING: Use care when pressing the detector element into the housing to avoid damaging the female socket contacts.

5. Using Figure 4 on page 4 of this sheet as a guide, unscrew the coupling nut from the cap. Remove the #2 screw from the therm istor mount so that it is free to revolve in the cap.

6. Holding the cap securely, use the spanner wrench

(P/N 14238) provided in the kit to unscrew the audio connector. Make sure that the thermistor mount also revolves in the cap in the same direction as the audio connector.

7. Check the value of the existing resistor against the val ue of the resistor incl uded in the kit. If they are the same value, leave in the existing resistor.

8. If the resistor val ues are different, unsolder the existi ng resistor and replace it with the new resistor from the kit.

Solder the resistor across pins 1 and 5. The red wire must be re-soldered back into connector pin 1.

9. Screw the audio connector back into the cap, alloWing the thermistor mount to revolve in the same direction as the connector.

DETECTOR PERFORMANCE EVALUATION

PROCEDURE

This test will check the detector for proper linearity and

VSWR characteristics.

Standard procedures can be used to check return loss. The measurement of return loss up to a frequency of 34GHz requires considerable care if measurement errors are to be avoided. It is highly recommended that a slotted line be used, or to use couplers or bridges with open/short calibration and an air line during the measurement procedure.

To check linearity, the power meter or analyzer compatible with the detectors must be within proper calibration. To supply power to the detector, a source with a power output between 0 and 16dBm must be used. This is usually a30 to 50MHz sourceof40mW. The source must have harmonics down at least 50dB, and a well matched step attenuator (10dB steps, return loss greater than

20dB, and a 70dB range). Due to the tightness of the linearity specification for the detectors, the coaxial attenuator must have a correction chart with it allowing the attenuation to be known within 0.03dB down to

-40dBm, and within 0.1 dB below -40dBm.

Connect the attenuator between the detector and the source. Starting with 0 attenuation, step the attenuator in

10dB steps. If detectors forthe 1038-HIV System are being checked, measurement accuracy should be 0.1 dB/10dB plus 0.5dB at -50dBm. If detectors for the Model 1045 or

Model 1034A are being checked, use the linearity curves of either Figure 5 or Figure 6 on page 4 of this sheet for comparison.

1. GENERAL INFORMAnON

1.1 WAVETEK MICROWAVE, INC. (WMI)

MODEL 1034A PORTABLE RF POWER

METER

The WMI Model 1034A Portable Power Meter is used with an RF power detector to indicate the power level incident upon the detector. A panel meter with a scale length of 4 1/2 inches indi­ cates the power on three scales. The two top scales cover a decade range of power with a one decibel overlap. The top scale indicates power in linear terms, and the scale below it indicates in decibels. The third (bottom) scale covers a

50dB range from -40 to +1 OdBm and indicates in dBm. One of seven ranges can be selected by push buttons arranged in a column on the right side of the meter's front panel. These will cause the meter to read on-scale for the decade ranges as long as the input power is within the measurement range of the instrument. An addi­ tional button at the top of the column selects the -40 to +IOdBm range.

A calibration factor control allows the sensitiv­ ity of the instrument to be set to compensate for variations in detector calibration factors.

The calibration factor for the detector is sup­ plied in the form of a chart showing the calibra­ tion factor at several different frequencies throughout the operating frequency range of the detector. By setting the control to correspond to that given for the detector at or near the specific frequency of the test signal, the instru­ ment will compensate for this fdctor and read it as if the calibration factor were unity. 50 to 75 ohm adapters are available as accessories.

These will reduce the effective sensitivity by

1.76dB. To compensate for this, the sensitivity of the instrument can be increased an equiva­ lent amount by switching the slide switch on the left of the meter to the 75 oh m position. It is important to be sure that the switch has been returned to the 50 ohm position when the adapt­ er is not in use.

There will be a small change in the sensitivity of the detector with a change in the tempera­ ture. The detector is equipped with a tempera­ ture sensor to allow compensation for this ef­ fect, but there can be some small residual vari­ ation. To allow the operator to adjust for this

1-1

From the library of WØMTU and to provide a convenient self-test feature, there is a calibration signal available from the front panel connector. This signal is very stable with respect to changes in temperature, has very low harmonic output, and is precisely matched to 50 ohms. The bottom push button on the right-hand column turns on the calibrator and selects the range for the instrument to read full-scale when connected to the calibrator out­ put. A screwdriver adjustment adjacent to this button sets the instrument for a correct read­ ing. To measure low level signals, it is neces­ sary to check to see that there has been no ap­ preciable zero drift in the instrument. Like all power meters, the Model 1034A will drift some­ what if the detector temperature is changing.

Ideally, the detector should be connected to the measurement system with the power turned off, and the instrument set for an indication in the center scale "Zero" range. This is done by pressing the ZERO button and adjusting the screwdriver control next to the button.

To allow plotting of the power indication on an

X- Y plotter, there is an analog output on the front panel. The output is 1.1 V for d full-scale deflection of the meter. Since there is an 11 dB range on the meter scale, this represents 0.1 V for each dB on the single-range scale. For the

-40 to +10dBm scale, the corresponding factor is 0.0 167V IdB, or 60dB per volt. The recorder input must be isolated from ground.

The 1034A will operate steadily from its bat­ tery, without line power, for more than 10 hours. To recharge the battery, the instrument is plugged into the line power source with its power switch off (the pilot light will not be lit) for 14 to 20 hours. The unit can be left con­ nected to the line at all times with no danger of damage to the battery. Recharging will take place if the instrument is turned on during the charging cycle, but the recharging time will in­ crease to approximately 40 hours. If the power is supplied during normal use, the battery will remain charged and battery power will be avail­ able when needed.

INITIAL INSTRUCTIONS

2.1 RECEIVING INSTRUCTIONS

Inspect the instrument for any shipping dam­ age. Be sure that all portions of the shipment are located and removed before discarding the shipping container.

2.2 RETURNING THE INSTRUMENT

If it is felt the instrument should be returned to

WMI for any reason, it is recommended that the

Wavetek Microwave Customer Service Depart­ ment be contacted prior to sending back the unit. It is often the case that many problems can be resolved by telephone or Telex without the necessity of returning the instrument. The telephone number is (lj.08) 73lj.-5780, extension

260, or Telex 3716lj.60.

2.3 POWER REQUIREMENTS

Before applying power to the instrument from the line, be sure that the instrument is set for

the correct line voltage. When the instrument leaves the factory, a plate is installed just above the power input connector showing the correct line voltage. If it is required to change the line voltage, the large screws at the left and right center of the front panel and the screws on the bottom of the case should be re­ moved. Lift the instrument out of its case to allow access to the line voltage switch. Move the switch to expose the correct line voltage in­ dicator on the moveable plastic part of the switch. If the 115Y indicator is exposed, stan­ dard units will operate from 115Y ac ±IO%. If the 230Y indicator is exposed, the unit is set to operate from 230Y ±10%. If equipped with op­ tion Olj., the unit will operate from 100Y ±10% if set to 115Y, or 200Y if set to 230Y. If equipped with option 01 (battery) the 115Y setting will cover the range from 180Y to 256Y. If the switch setting is changed, be sure to remove the plate above the power input connector and rein­ stall it so that the correct voltage is facing up

(the plate is marked on both sides).

2.4 CHASSIS GROUNDING

WARNING: Failure to properly ground the instrument can allow dangerous volt­ age levels to build up on the chassis which could be dangerous to operating personnel.

The 103lj.A is supplied with a three conductor power cord. The instrument will be properly grounded if the plug is connected to a proper ly grounded three-prong receptacle. If a three prong to two prong adapter is used, be sure that the extra lead from the adapter is grounded.

If the unit is equipped with option 01 (battery), it can be operated independently of the power line. The internal supplies are low voltage and no danger is present in the 103lj.A itself when in the battery mode. However, without the power cord connected, the unit will not be grounded and the chassis will assume the potential of the device to which it is connected. Many types of microwave sources operate with potentially le­ thal internal voltages. For this reason, it is ex­ tremely important for the operator to be sure that the device to which the 103lj.A is connected is safely grounded.

2.5 DETECTOR HANDLING

Caution: Before handling the detector in­ cluded with the 103lj.A, read the "Handling

Precautions" at the

bottom

of the "Detec­ tor Element and Tracking Resistor" Tech­ nical Information sheet located at the end of Section I (preceding).

All detectors will be damaged if too much RF power is applied to them, so be sure to observe the warning affixed to the detector housing.

The coaxial detector used with the 103lj.A has a maximum rating of 200mW (+23dBm). It should be determined prior to testing that the power output of the device under test will not exceed tha t specifiea tion.

3. OPERATION

3.1 FRONT PANEL CONTROLS

The following controls are located on the front panel of the 1034A. For reference, a photo­ graph of the front panel is shown on the attach­ ed page in Figure 3-1.

3.1.1 Power Switch

This push-push switch is arranged so that power will be ON when the switch is out. When the cover is placed on the instrument case a plastic rod forces the switch in, ensuring that the pow­ er is off and the battery is not being drained.

The fastest way to recharge the battery is with the unit connected to the ac line with the power switch off. A pilot light adjacent to the switch indicates if the instrument is turned on, but will not light during charging only.

3.1.2 Meter Range Push Buttons

Eight of the ten buttons on the right side of the meter control the ranges that can be selected for the meter. The top button (A-E) selects the bottom dBm scale of the meter, covering the range from -40 to + I OdBm. This range is useful if the power being measured will be varying over a wide range; for example, when adjusting a filter or an antenna at the start of the adjust­ ment procedure. It is also useful to determine the approximate power delivered by a source to the meter so that the proper range limit button can be selected. Between the major divisions of this scale are the letters A through E, indica­ ting the appropriate expanded range for the power being measured. Below -40dBm there is no accurate indication of power so that a selec­ tion of the bottom two expanded ranges must be made by trial. The seven expanded range scales are selected by the buttons below the top one

(A-E). The values for the full-scale readings on the two uppermost scales of the meter are in­ dicated to the right of each of the buttons. The top indication of the two is for the top scale of the meter (linear values), and the bottom indic­ ation refers to the next scale down (dB). The expanded scales provide the best resolution and the accuracy specified for the instrument. If a reading greater than +lOdBm is indicated, the power to the detector should be reduced with­

3-4

From the library of WØMTU out delay because the +23dBm (200m W) destruc­ tion point of the detector diode could be gener­ ated by the power source.

3.1.3 Zero Button &: Screwdriver Adjustment

Pressing the ZERO button causes the meter to indicate the correct zero signal balance adjust­ ment for the input circuits of the instrument.

With no RF power applied to the detector and the ZERO button depressed, the screwdriver ad­ justment adjacent to the ZERO button is set to cause the meter to read in the small range marked "Zero" in the center of the meter's scale.

3.1.4 Cal Button &: Screwdriver Adjustment

Pressing the CAL button turns the calibration oscillator on, disconnects the CAL FACTOR control, selects the DIRECT 50li position, and puts the meter on the "A" scale. When the de­ tector is then connected to the CAL OUTPUT connector, the CAL screwdriver adjustment can be set to cause the instrument to indicate ex­ actly 10mW, or full scale.

3.1.5 Calibration Factor Control (dB)

This control adjusts the sensitivity of the in­ strument to compensate for variations in detec­ tor sensitivity with changes in frequency. A calibration chart is provided with the detector that gives the correct setting of the CALIBRA­

TION FACTOR control for a number of discrete frequencies within the operating range of the detector. The control should be set to corres­ pond to the point on the detector's calibration chart closest to the operating frequency. If the detector is being used in conjunction with a di­ rectional coupler or attenuator of known cali­ bration, the control can be set to compensate for both the detector and the additional de­ vice. The meter will then read directly . .

3.1.6 Direct 50 li /75 li Adapter Switch

Normally, this switch will be left in the 50 li ­ posi tiona If a 50 to 75li adapter is connected in front of the detector, the switch can be set to

75li to correct the reading for a 1.76dB adapter loss.

Model 1034A

3.2 INTERNAL CONTROL, LINE VOLTAGE

SWITCH

The 1034A can be operated on various line volt­ ages as well as the internal battery. See Sec­ tion 2.3 on page 2-1 for a complete discussion of the line voltage settings available.

3.3 FRONT PANEL METER

The mirror-backed front panel meter indicates power readings on three scales. The bottom scale covers a 50dB range, and is selected by the top button on the panel. The top two scales are selected by the buttons below the top but­ ton. These scales cover 11 dB, which allows a

1dB overlap for each 10dB range. In addition to the power indicating ranges, there is a center scale marking which shows the correct zero ad­ justment range. Just below the mirror-backed meter there is a mechanical zero adjustment provided to screwdriver-adjust the position of the pointer on the meter. This adjustment should be made with the instrument placed in the position in which it will be operated (laying down or standing up). The adjustment is correct when the pointer moves in the same direction as the adjustment screw, and lies on the scale markings at the left edge of the scale when the instrument is turned off.

1.1 V. Since the expanded 10dB ranges cover

11 dB on the meter scale, this would be equal to

0.1 V/ dB on those ranges. On the -40 to + 1OdB m range, the coefficient is l6.7mV/dB or 60dB per volt. The output impedance is approximately

10K ohms. This output is provided to drive recorders or plotters with inputs isolated from ground. If the output is connected to grounded devices, ground currents can occur which will give low-level power measurements with grossly inaccurate readings.

3.4.3 Cal Output lOmW, Type N Connector

The internal calibration oscillator supplies

10mW ±1.5% of RF power when the CAL button is pressed. The source impedance is 50 ohms

±2% (S WR less than 1.04), and harmonics are down 50dB with respect to the signal level.

When the detector is connected to the CAL

OUTPUT and the CAL button is pressed, the

CAL screwdriver adjustment is used to cause the instrument to read full-scale. This will adjust the calibration for all ranges.

3.4 FRONT PANEL CONNECTORS

The following connectors are located on the front panel of the l034A, as shown in Figure 3­ l:

3.4.1 Power Input

This three prong male jack is used to supply power to the instrument when it is operating from the ac line or the battery is being re­ charged. The connector conforms to 1. E. C. specifications for six ampere connectors with a grounding pin. Be sure that the instrument is connected to a properly grounded ac supply.

See the Warning of Section 2.3 on page 2-1.

OPERATING PROCEDURE

WARNING: Continuous or peak power levels in excess of +23dBm (200mW) can damage or destroy the diode power sensing device of the detector. Always take precautions to ensure that the power applied to the detector will be well below this level before connecting the detector to any RF power source.

Connect the line cord if the instrument is to be run from the ac line or if the battery is to be recharged. Be sure to observe the Warning of Section 2.4 on page 2-1.

Turn the 1034A ON by pressing the

POWER switch and allowing it to pop out. The pilot light will illuminate when power is applied. If the condition of the battery charge is not known, con­ nect the detector to the CALIBRATION

OUTPUT and press the CAL button. 1£ the same detector is being used that was last used with the instrument, the meter reading should be within a few tenths of a dB of full-scale. If not, a

Model 1034-A

3.

4-.

5.

6. discharged battery should be suspec­ ted. The best method of determining that the battery is fully charged is to connect the instrument to a source of line power for 16 hours or more (such as overnight). The battery will then be ready for 10 hours of use. There is no danger of overcharging the battery.

Check the calibration by connecting the detector to the CALIBRATOR OUT­

PUT. Adjust the CAL screwdriver ad­ justment to obtain full-scale deflection of the meter. This step can be com­ bined with the battery check of step 2 if desired.

If it is possible to turn off the RF power source that will be measured, do so and connect the detector to the source. If the source cannot be turned off, leave the detector on the CALIBRATOR

OUTPUT. Press the ZERO button and adjust the ZERO screwdriver adjust­ ment so that the meter reads in the

"Zero" range.

Consul t the calibration factor chart on the detector and set the CAL FACTOR control to the value given for the fre­ quency nearest the frequency of the power source. If the power of the source is not approximately known, con­ nect enough attenuation to be sure that the power will be below +IOdBm. Press the top button (A-E) and read the power on the -4-0 to+ 10dBm scale. The ap­ proximate power level can then be de­ termined so that the amount of attenu­ ation required (if any) can be selected.

To measure power, first press the top button. Since the lower scale covers the entire range of the instrument, it is convenient to use if precise measure­ ments are not required. If a precise determination is required, observe the letter lying between the same two ma­ jor divisions as the pointer. Press the button corresponding to the indicated letter and read the power on the top scales. If the power is below -4-0dBm, try the -4-0 or -50dBm scales to obtain the best reading. If a reading greater

3-6

From the library of WØMTU than full-scale on the top range is ob­ tained, reduce the input power without delay because the meter will not indi­ cate any further increases in power that could be great enough to destroy the detector.

If low power levels are being measured, periodically check the ZERO adjust­ ment. This is particular Iy important for a period of one hour after turn on or when there has been a change in the ambient temperature in which the in­ strument is operating. The CAL adjust­ ment should not require rechecking un­ less the ambient temperature has changed by several degrees. The CAL adjustment must be rechecked when­ ever detectors are changed.

3.5.1 Use of the Analog Output

The analog OUTPUT connection can be used for driving recorders and plotters. See Section

3.4.2 on page 3-5 for the description of this feature.

ELECTRICAL DESCRIPTION

4.1

INTRODUCTION

Figure 4-1 on the attached page shows a block diagram of the major circuits contained in the

1034A. The block diagram will be described first, and then the circuits within the blocks will be described in detail. To better under­ stand the discussion of the circuits shown within the blocks of the diagram, refer to the sche­ matic diagrams of Section 7.

4.2 BLOCK DIAGRAM DESCRIPTION

4.2.1 RF Detector

To use the power meter, an RF detector must be connected to its input for sensing the various power levels of a device under test. The detec­ tor converts the RF power incident upon it to a dc voltage. This voltage is proportional to pow­ er at very low RF input levels, and gradually becomes proportional to RF voltage at high input levels. The sensitivity at low levels and the point at which it starts to deviate from a square (power) law device are functions of the detector temperature. Accordingly, the detec­ tor temperature is monitored and appropriate corrections applied to the circuits following the detector. Also, there are slight differences in sensitivity from one detector to the next. For this reason, a

resistor with a factory-deter­

mined value related to the sensitivity of each specific detector is mounted in the detector as­ sembly. Four leads come from the detector.

These consist of a common lead tied to the de­ tector housing, a power sensing lead, a lead from the thermistor, and a lead from the detec­ tor sensitivity compensating resistor. The ther­ mistor is mounted inside the detector housing and is in intimate contact with the brass shell of the housing.

4.2.2

Thermistor Bridge Amplifier

The

thermistor bridge amplifier converts the

high impedance signal from the thermistor to a low impedance signal

which is very nearly pro­

portional to temperature. The amplifier feeds the compensation circuits and the log amplifier so that the square-law compensation and sensi­ tlVlty of the instrument will be correct regard­ less of the detector temperature.

4.2.3

Preamplifier

The preamplifier is a high impedance, low noise amplifier. It

is chopper stabilized to reduce

drift to an absolute minimum. A 1kHz integrated circuit oscillator provides drive voltages for both the input chopper amplifier and the stabilizing chopper amplifier used for the log amplifier circuitry. The gain of the preamplifier is switched; for ranges below

-20dBm full scale it is 100, and for ranges above and including -20dBm it is 10. The preamplifier feeds the log amplifier directly for all ranges.

In addition, it feeds the log amplifier indirectly through the compensation circuit on the ranges above -30dBm full scale.

4.2.4

Compensation Circuit

The compensation circuit starts to become active when the RF power input level reaches approximately -27dBm. At the output of the preamplifier, this level will be amplified to about 15m V using the gain of 10 of the -20d Bm range. At this level there is no need for chop­ per stabilization and none is provided. The compensation circuit generates a current pro­ portional to the square of the input voltage.

This current is summed in with the current from

the preamplifier at the input to the log ampli­ fier. At high signal levels the detector output voltage deviates from square-law, but the cur­ rent from the compensation circuit increases so that the total current still corresponds to a correct square-law signal. The amount of com­ pensation required depends upon both the tem­ perature and the characteristics of the particu­ lar detector • To cause the circuitry to respond properly to changes in temperature and the use of different detectors, connections are made to the

thermistor bridge amplifier and the factory­

selected

resistor contained in the detector as­

sembly.

4.2.5 Logarithmic Amplifier

The logarithmic (log) amplifier has a very wide dynamic range; from less than 0.5mV to greater than an equivalent input of 100V. In order to be free of drift over that range, it is chopper sta­ bilized. A transistor is used as the logging ele­

-

Model 1034A ment. Its output is temperature dependent and must therefore be compensated for changes in temperature. An amplifier following the log­ ging circuit provides a gain of 15, thus raising the signal level to 100m Y/dB.

4.2.6 Full-Scale Range Changing

The Model 1034A uses three methods to change the full-scale range of the instrument. These consist of: (1) Changing the gain of the input preamplifier; (2) Changing the current supplied to the temperature compensation circuit, and;

(3) supplying differing offset currents to the output summing amplifier. The selection of the size of the span of the range (i.e. whether the scale covers 11 dB or from -40 to + 10dBm) is de­ pendent upon the gain of the output summing amplifier. A more complete discussion of the range changing arrangement follows in the de­ scription of the individual circuit blocks.

4.3 INDIVIDUAL CIRCUIT BLOCK DE­

SCRIPTIONS

The following descriptions refer to the sche­ matic diagrams (SD) located in Section 7. Un­ less otherwise indicated, the majority of the discussion refers to SD 12932 and the reference designators mentioned in the discussion should be prefixed with A2.

4.3.1 Input Preamplifier

The input preamplifier is a chopper amplifier.

It consists of an input chopper to convert the input dc voltage to square wave, a high gain ac amplifier, a synchronous detector to convert the amplified square wave back to dc, and a dc amplifier to provide additional gain and low output impedance. An oscillator circuit pro­ vides the switching waveforms required to drive the chopper and synchronous detector. Overall feedback determines the gain and makes the amplifier less dependent upon the parameters of the circuit components than an open loop ampli­ fier would be.

Integrated circuit U2 is a combination oscillator and frequency divider chain. The oscillator runs at 64kHz and the six stage divider divides the frequency down to 1kHz. Outputs from the 2 and 4kHz dividers are combined in U3 to pro­ vide narrow pulses to dr ive the synchronous de­ tector. Figure 6-1 on page 6-7 shows a timing diagram for this circuit. Square wave signals of opposi te phase are supplied to Q 1 and Q2, alter­ nately turning on one and then the other. The result is that the input of the ac amplifier is first connected to the input signal, and then to the feedback resistor. The ac amplifier consists of the transistors Q5 through QIO. It has suf­ ficient bandwidth so that the signal at the emit­ ter of QIO is essentially a square wave with an amplitude proportional to the difference be­ tween the input and the signal fed back from the output of U 1. Q 11 and Q 12 are turned on briefly at alternate ends of the square wave period. Transient signals that occur due to the switching of the inputs to the amplifier have decayed by the time the output switches are turned on at the end of the cycle. The feedback resistive divider is selected to allow a gain of

100 for ranges of -30dBm and below. For ranges above and including -20dBm, the divider is set for a gain of 10. Ql3 short circuits the unused resistor of the divider when a gain of

100 is selected. This keeps leakage currents from the range switch out of the amplifier. Q4 and Q7 generate a gating action which turns the amplifier off during the instant of switching, thereby reducing the effect of the switching transient.

4.3.2 Log Conversion Circuit

The log conversion circuit is a high gain opera­ tional amplifier with feedback from the collect­ or of a transistor. The emitter-base voltage of the transistor is proportional to the log of the collector current over many decades of current values. At 25

0

C, the emitter-base voltage changes by 60mY for each factor of ten that the collector current changes. This factor is di­ rectly proportional to the absolute temperature so that for each degree C of temperature varia­ tion, the factor will change by about 0.3%. This change with temperature is compensated for by using a thermistor, R T 1, to shunt the amount of current caused by the increase in temperature away from the input summing amplifier, Al U 1.

The operational amplifier segment of the log conversion circuit is chopper stabilized by using an amplifier similar to the one used in the input preamplifier. Since the sensitivity is not as great, the circuit is simpler. The integrated

4-5

From the library of WØMTU

Model 1034A amplifier, U8, receives ac signals directly through C34. DC signals are routed through the chopper amplifer and go to pin 3 of U8. The current summing junction is common to the chopper amplifier and to C34. If the summing junction is not at zero dc potential, the chopper switching transistor, Q14, will convert the po­ tential to an ac signal. The ac amplifier, U7, amplifies the signal and supplies it to the syn­ chronous demodulator, Ql5 and Q16, where it is converted to dc. A low pass filter, R76 and

C35, removes the ac component and the dc cor­ rection signal goes to pin 3 of U8. This causes the output of U8 to change the current through the logging transistor to bring the sum ming junction back to zero.

In addition to the logging factor changing with temperature, the saturation current of the log­ ging transistor also changes. To compensate for this effect, an additional transistor is supplied with a fixed current (for a given range), and a differential amplifier amplifies the difference in the emitter-base potential between the log­ ging and compensation transistors. The two transistors are mounted in the same package,

Q 18. The differential amplifier is U 1O. U9 is an operational amplifier, with the compensating transistor providing the feedback so that the emitter-base potential of the transistor is the log of the current supplied to the summing point at pin 2. Range switching for the top three ranges is accomplished by changing the current supplied to the compensating transistor (by a factor of ten) for each range.

4.3.3

Square-Law Compensating Circuit

Above about -27dBm, the detector begins to significantly depart from square law. Since the instrument is required to be linear in power, compensation is required. This is so that the total current supplied to the logging circuit summing junction continues to be square law at all levels over the total range of the instru­ ment. This is accomplished by generating a sig­ nal proportional to the square of the input sig­ nal and adding it to the input at the log ampli­ fier summing junction. This signal is negligable at low input levels, and is many times larger than the input signal at high input levels. The squaring function is implemented by first log­ ging the input signal, amplifying the logged sig­ nal by a factor of two, and then taking the antilog.

4-6

Integrated amplifier U4 has feedback supplied by the diode connected to pin 8 of U5. The voltage at pin 8 of U5 will be proportional to the log of the input voltage at levels above -27­ dBm. The circuit will be inactive at low levels due to the offsetting action of R40. The diode connected to pin 11 of U5 acts merely to limit the voltage excursion of U4 when the circuit is inactive. The diode connected to pin 5 of U5 transmits the signal to U6, and compensates for changes in saturation current in the logging diode due to changes in temperature. Amplifier

U6 has a gain of 2 (slightly adjustable by R48), and supplies the amplified voltage to the diode connected to pin 2 of U5 causing the antilog function to become active. The diode connect­ ed to pin 3 of U5 compensates the antilogging diode for changes in saturation current due to temperature changes. All of the diodes in U5's circuitry are essentially identical bec2;Jse they are part of an integrated circuit. The current from pin 1 of U5 is thus proportional to the square of the input voltage, and it adds directly with the current from the input preamplifier at the input summing junction of the log ampli­ fier. The circuit is switched off for ranges below -20dBm full scale to avoid the possibility of leakage currents causing errors below the levels where compensation is required.

4.3.4 Temperature Compensation

Amplifier U 11 supplies temperature compensa­ ting signals to the square law compensation cir­ cuit by way of R61 to correct for shifts in de­ tector sensitivity caused by temperature chang­ es, and to the output amplifier, Ai Ui, to cor­ rect for changes in overall sensitivity. The sig­ nal supplied to the compensation circuit cor­ rects only for linearity, so additional correction is required at AIUl. Ull is arranged as a bridge amplifier fed from a high impedance thermistor. The output of the amplifer is very nearly proportional to temperature over the temperature range of 0 0 to 50°C.

4.3.5 Range Switching

The range of the 1034 A is controlled by three parameters as described in Section 4.2.6 on page 4-5. The operation of the switching action can be seen in Table 4-A on the next page. The equivalent dB values are selected so that the sum of the full scale signal signal and the dB

From the library of WØMTU

Model 1034A values will be zero for each range except for the -40 to +lOdBm (A-F) range. This corre­ sponds to the meter dB reading at full scale.

On the (A-F) range the gain of the output am­ plifier is decreased by a factor of six so that a normal full scale reading of +10dBm would only deflect it IldB up scale. The scale is arranged for 66dB for full scale, so an offset of 55 dB is required. Note that increasing the log compen­ sating current has the effect of decreasing the magnitude of the signal from the differential amplifier, U9.

(. I emitter of AIQl to maintain oscillation at the correct level. Diodes AICR3 and AICR4 com­ pensate the circuit for changes in the rectifica­ tion characteristics of AICR5 when there is a change in temperature.

4.3.7 Power Supply

An ac voltage drives the rectifiers CRlO through CR 13 to supply unregulated dc voltages to the filter capacitors C46 and C47. Regula­ ted dc voltages are derived from these by inte­ grated circuit regulators, U12 and U13. The regulators are provided with circuits to limit the current to a safe value and prevent damage in the event of a short circuit of short dura­ tion. For operation from the ac line, a trans­ former supplies the ac voltage to the recti­ fiers. Battery option instruments have an oscil­ lator supply which generates an ac voltage for the rectifiers. The battery supply generates the ac voltage by a modified form of multivibrator

A3Q3 through A3Q6. The circuit oscillates at

30kHz to supply power to the rectifiers through

A3T2. Charging of the battery occurs whenever the line voltage is connected to the instru­ ment. Integrated circuit A3U 1 maintains the peak of the rectified line frequency waveform at a constant value regardless of the input line voltage. A3RTl causes the voltage to vary with temperature in accordance with the battery's requirements. Current from the regulator is limited to a safe value.

4.3.6 Calibrator Oscillator

Referring to SD 13065, transistor AIQl is ar­ ranged in a ground based oscillator circuit with feedback supplied to its emitter through Al­

C14. It feeds the CALIBRATOR OUTPUT con­ nector through a 5 pole low pass filter and a

4dB attenuator to assure freedom from harmon­ ics and a good source match at the output. The diode AICR5 rectifies the peak voltage supplied to Al R32, thereby generating a dc voltage pro­ portional to the RF voltage from the oscilla­ tor. Amplifier Al U2 compares this voltage to a stable dc signal derived from the -12V power supply and supplies just enough current to the

5. PERFORMANCE VERIFICAnON TESTS

5.1 GENERAL

. The purpose of this section of the manual is to provide a means of verifying proper operation of the Model 1034-A for receiving inspection and when making periodic performance evalua­ tions. If the instrument passes the tests given in this section, it can be assumed to be opera­ ting proper ly and used wi th confidence. These tests do not check the operation of the power detector as they are only intended to check the health of the indicating instrument. The power detector can be checked using a properly cali­ brated 1034-A as an indicating unit. Alterna­ tively, the detector can be checked by using the

Detector Performance Evaluation Procedure given on page 2 of the "Detector Element and

Tracking Resistor Replacement Procedures"

Technical Information sheet located at the end of Section 1 in this manual.

5.2 EQUIPMENT REQUIRED

The following equipment is required to perform the measurements given in this section. a. A precision dc power supply capable of

0.01% accuracy and with the ability to be set to 70uV. It is possible to use a preci­ sion voltage divider constructed of 0.01% resistors wi th an attenuation factor of 100

(4-0dB) to obtain the voltages called for in the first three lines of Table 5-A. Such a divider can be made from 990 ohm and 10 ohm 0.01% resistors. In order to apply voltages to the input of the instrument an adapter must be constructed. Figure 5-2 shows a diagram for the fixture. The re­ sistors shown can be conveniently posi­ tioned within the male plug mating with the instrument. In addition, a 50 ohm

0.1 % resistor will required when checking the calibrator output. The resistor should be placed in an adapter box with a con­ nector mating with the power supply on one side and a Type N female connector on the other side. Suitable boxes can be obtained from most electronic parts dis­ tr ibuters. The resistor should be connect­ ed from the high side of the power supply connector to the center pin of the Type N connector. The low side of the power sup­ ply and the shell of the Type N connector should be tied together. b. A digital voltmeter (DVM) with 0.01 % ac­ curacy and luV resolution. If it is not planned to check the output of the Cali­ brator, lmV resolution and 0.1% accuracy will be satisfactory.

Checking the Calibrator Output

Figure 5-2. Fixture for Applying DC Voltage to the Model 1034A c. For checking the Calibrator output, a

Thermal Voltage Converter will be needed to be used as a transfer standard. The maximum voltage range is IV. A unit such as the Fluke Model A55 Thermal

Transfer Standard or equivalent is recom­ mended. It is required that this device be matched to 50 ohms. The impedance of the converter is approximately 200 ohms, so it is necessary to measure its resis­ tance very accurately (within 0.1%) and select a value of resistance to place in parallel with it to make its value become

50 ohms ±1%. Make all connections very short, preferably soldering the resistor across the end of a Type N Tee connector as shown in Figure 5-1. Be careful not to apply a voltage in excess of 1 V to the

Converter when measuring its resistance or the Converter could be destroyed.

5.3 TRACKING WITH DC VOLTAGE

In order to operate correctly with a power de­ tector connected to its input, the instrument must respond as shown in Table 5-A. If the pre­ cision dc power supply being used does not have adequate low level accuracy or stability, the measurements given in the first three lines of

Table 5-A must be made with the attenuator descr ibed in Section 5.2.a in place. In any case, the instrument ZERO setting must be adjusted after connecting the power supply or attenuator and just before the measurements called for in

Table 5-A are made. To do this, set the power supply to zero volts and follow the procedure given in Section 3.5 on page 3-5. Also, the CAL setting must be adjusted by setting the power supply to O.7mV, pressing the -30dBm button, and adjusting the CAL setting so that 1.1 V

±lmV is measured at the OUTPUT connector.

The voltages called for in Table 5-A can now be applied.

Model l03lJ.A

Two sets of observations must be made at each input voltage level except the last one. Take the readings indicated for both settings of the range buttons at each input level.

5.4 CALIBRATOR OUTPUT LEVEL CHECK

Set the precision power supply to l.lJ.llJ. V and connect the 50 ohm resistor assembly to the output of the supply. Connect the DVM to the output of the converter. Connect the converter

(modified for 50 ohm impedance as previously described) to the resistor at the output of the supply. Record the reading of the DVM, reading it to a precision of luV. Reverse the polarity of the power supply and record the new reading with the same 1uV precision. Press the CAL button and connect the converter assembly to the CALIBRATOR OUTPUT. Read the DVM.

Compare the reading with the average reading obtained when the converter was connected to the power supply. If the two differ by more than 1 %, reconnect the converter to the supply and set the supply so that the voltage from the converter is the same as it was when connected to the CALIBRATOR OUTPUT.

Note the reading of the supply, reverse the polarity, and again set the supply so that the thermal converter output matches what it had been when attached to the CALIBRATOR OUT­

PUT . Aver age the two supply voltages. When this is done, the supply voltage should be between 1.lJ.25V and 1.lJ.03V. It may be neces­ sary to repeat the procedure several times in order to get consistent results.

This completes the Performance Verification

Tests for the Model l03lJ.A. If the instrument does not meet one or more of the performance criteria, it should be calibrated according to the procedures given in Section 6, the next section.

6.3 CALIBRA nON

6.3.1 Equipment Required

The following equipment is required to calibrate the Model 1034-A. Specifications given for the equipment are minimum. Equipment capable of better performance can, of course, be used. a. b.

A digital voltmeter (DVM) with 0.03% accuracy and four digit resolution with

20% over-range capability. On the most sensitive range the least signifi­ cant digit must be 10uV or less. Re­ commended is the Fluke Model 8600A

Digital Multimeter or equivalent.

A precision power supply covering the range between 7uV and 1V with accura­ cy and resolution of 0.1 %. At the 7uV level, it is only necessary for the supply to have 1% accuracy for changes in voltage setting. A small, fixed offset of a few microvolts is acceptable. In order to achieve satisfactory low level performance from some manufacturer's models, it may be desireable to make a voltage divider consisting of a 990 ohm and a 10 ohm ±0.01 % resistor. This will attenuate the output by 4-0dB (100:1) and permit the supply to operate at high level even when a small output is re­ quired. A recom mended instrument that will not require a divider is the

When used, it is required to measure its input resistance and connect enough resistance across its input to change it to 50 ohms ±l %. See Figure 5-1 on page 5-2 for an illustration of this ar­ rangement. In addition, an adapter is needed to connect the assembly to the output of the calibrator.

An adapter box with double banana plugs on one side and a Type N female connector on the other side. A 50 ohm

±O.l % resistor should be used to con­ nect the center pin of the Type N to the high side of the double banana plug.

The low side of the double banana should tie to the Type N shell.

A frequency counter capable of count­ ing 30MHz from a 50 ohm source with a

1.1 V open circuit output. The counter should be able to count 1kHz while pre­ senting an impedance of 1M ohm shunt­ ed by a few pF for use in measuring the chopper frequency. The signal level for this is greater than 5V.

6.3.2 Calibration Procedure

The components used in the Model 1034A are extremely reliable and generate little heat.

Consequently, there is little drift due to com­ ponent aging, and adjustments are rarely re­ quired. It is strongly recommended that if mea­ surements indicate that an adjustment is set within the specified range, that is not attempt­ ed to put it "right on". It is often the case that variations in the equipment being used to con­ duct the test account for small differences in measured values. Since many adjustments are interactive, be absolutely sure that an adjust­ ment is really required before making it.

If a component is replaced, depending upon its location in the circuitry, only certain of the calibration steps need be performed. In gen­ eral, only those steps shown in the section per­ taining to the specific circuit that has been re­ paired need be carried out.

Since the detectors used with the Model 1034A are interchangeable, the entire test procedure makes use of standardized dc voltages applied

6-3

From the library of WØMTU to the input in lieu of a detector. In order to simulate the detector temperature compensa­ ting thermistor and individual calibration resis­ tors, resistors must be connected to pins within the instrument. Connect aiM oh m ±5% resis­ tor between pins 14 and 12 on the A2 board, and a 162K ohm ±l % resistor between pins 9 and 12 on the A2 board. If a number of instruments are going to be calibrated, it will be worthwhile to make a connector to fit on the front panel

INPUT connector with these resistors perman­ ently installed. See Figure 5-2 on page 5-2. In this case, the 1M oh m resistor is installed be­ tween connector pins 2 and 4 and the 162K ohm resistor between pins 3 and 4. A shielded pair of wires can be brought out from pins 1 (center conductor) and 4 (shield). This is useful for sup­ plying dc calibration voltages to the input (cor­ responding to pins 15 and 16 of A2). A connec­ tor to mate with the front panel jack is avail­ able from WMI under part number 13357 or can be purchased locally as Switchcraft Part Num­ ber 2504M.

Before applying power to the instrument, adjust the mechanical zero of the meter so that the pointer is at the left edge of the scale. This should be done with the instrument in the posi­ tion in which it is normally used (standing up or lying down). Set the 50/75 ohm switch to 50 ohms, set the CAL FACTOR switch to 0 (cen­ ter), and remove the RF detector. With the ex­ ception of Step 1, following, and when the volt­ age at the output connector is measured, volt­ ages are to be measured with respect to the common test point, TP21.

The following steps must be carried out in the order listed. It will be helpful to read the en­ tire procedure through once before starting.

Allow at least one-half hour of warm up time, with the instrument connected to the dC line, before starting.

Step 1. Check and adjust the battery charg­ ing voltage by connecting the volt­ meter between chassis ground and

TP31. Set A3R4 to 3.S8V ±a.OI V.

Model 1034A

Step 2. Check the positive and negative 12Y supplies. Connect the voltmeter low side to common, TP21. Connect the high side to TP27 and verify -12.000Y

±O.5Y. Move the voltmeter's high lead to TP26, and verify + 12.000Y ±O.5Y.

Step 3. Connect the counter between com­ mon, TP21, and TP22. Check to see that the frequency is 1kHz ±lOOHz.

Disconnect the counter.

Step 4. Check to see that the ZERO control has sufficient range. Connect the voltmeter to TP23 and set the front panel ZERO control so that the volt­ meter reads OV ±1mV with the -30­ dBm button pressed. Move the volt­ meter to A2 pin 13 and measure the voltage. It should be less than about

±8V. If it is not, trouble with the input amplifier is to be expected.

Step 5. Check the mechanical centering of the knob for the CAL FACTOR con­ trol. Connect the voltmeter to pin 2 of A2 and set the CAL FACTOR con­ trol to obtain OV as close as possi­ ble. If the knob does not indicate 0 within less than one-quarter of a divi­ sion, loosen the two allen screws and reset it so that it does. Reset the

CAL FACTOR control to 0 for all of the following steps.

Step 6. Check the gain tracking of the input preamplifier. Using the precIsIon power supply, apply -l.OOmV to pin 15 of A2 with the grounded side of the supply connected to pin 16 of A2.

Connect the DV M to TP23 and press the -30dBm button. The DVM should read apprOXimately 100m V. Now turn the supply off and adjust the front panel ZERO control so that the DVM reads O.OOmV ±lOOuV. Press the -20­ dBm button and check that the DVM reads O.OOmV ±30uV. Readjust the

ZERO control if necessary to simul­ taneously obtain both conditions.

Once again apply 1m V from the pow­ er supply. Check and note the DVM readings for both the -30dBm and

-20dBm buttons pressed. The volt­ ages should be very nearly 100mV and

10mV respectively. The ratio of the two voltages must be 10.00 ±0.5%. If this is not the case, check to be sure the measurement has been correctly made. If it is established that the ratio is not within tolerance, trouble is indicated in the input amplifier or its feedback circuit. If correct, dis­ connect the power supply.

Step 7.

Step 8.

Step 9.

Using a clip lead, short pins 15 and 16 of A2 together. Move the power sup­ ply to TP25 and adjust the power sup­ ply to give -15mV. Connect the DVM to the front panel OUTPUT connector and adjust the front panel 10mW CAL control to cause the DV M to read

O.OOOV ±lmV with the -lOdBm button pressed. Press the -20dBm button and adjust (1) AIR9 (CAL OUTPUT) to obtain 1.000V ±lmV, and (2) AIR12

(METER CAL) to obtain a meter de­ flection of -ldBm.

Attach the power supply to TP25 and set for -15mV. Press the -IOdBm button and adjust the front panel

CAL control so that the DVM reads

O.OOOV ±lmV. Apply -150mV and ad­ just A2RI02 (LOG CAL) so that the voltage changes by l.OOOV ±lmV. It will be required to alternate between

-15 and 150m V, resetting the pot each time until the adjustment is sat­ isfactory.

Set the power supply for -150mV into

TP25. Press the -lOdBm button and ad just the front panel CAL control so

6-4

From the library of WØMTU

­

Model 1034A

-' that the DVM reads 1.000V ±l mY.

Press the OdBrn button and adjust

A2R88 (OdBm TRACKING) to obtain

O.OOOV ±lmV.

Step 10. Set the power supply for -1.5V into

TP25. Press the OdBm button and ad­ just the front panel CAL control so that the DVM reads 1.000V ±l mY.

Press the +lOdBm button and adjust

A2R83 (+lOdBm TRACKING) to ob­ tain O.OOOV ±lmV. Disconnect the power supply from TP25.

Step 11. Press the -30dBm button. Connect the DVM to TP23 and adjust the front panel ZERO control to cause a read­ ing of O.OOmV ±lOOuV. Remove the short circuit from the input terminals that was placed there in Step 7. Con­ nect a short circuit clip lead from

TP29 to TP24. Connect the power supply to the input terminals and set it for O.7mV. Move the DVM to the output connector and adjust the front panel CAL control to give 1.1 V

±lmV. Press the -20dBm button and adjust A2R70 (SECOND STAGE

NULL) to obtain 0.1 V ±lmV. Go back to the -30dBm button, reset the front panel control, and repeat the proce­ dure if necessary until both voltages are within ±lmV. Remove the short circuit clip lead.

Step 12. Set the front panel CAL control to its extreme counter-clockwise limit and be sure that the CAL FACTOR con­ trol is set to center (0). Set the power supply to apply -O.7mV to the input terminals. Connect the volt­ meter to the OUTPUT connector and adjust Al R36 (-30dBm RANGE CAL) to obtain 0.950V ±lmV.

The following three steps involve setting adjustments that interact with each other.

After proceding through Steps 13, 14, and 15, go back to Step 13 and repeat the procedure as many times as is required to obtain the results specified in the procedures. The process con­ verges to the correct results rather rapidly.

After going through the procedure several times, the required adjustments should be able

6-5

From the library of WØMTU to be accomplished without difficulty.

Step 13. Set the power supply to provide

-O.7mV to the input. Connect the voltmeter to the OUTPUT connec­ tor. Press the -30dBm button and adjust the front panel CAL control to obtain 1.100V ±lmV. Reset the pow­ er supply to provide -O.228V to the input. Press the OdBm button and set

A2R57 (MED LEVEL CAL) to obtain

1.100V ±lmV.

Step 14. Set the power supply to provide 48.6­ mV to the input. Press the OdBm but­ ton and adjust A2R48 (COMP AMP

GAIN) to obtain O.lV ±lmV.

Step 15. Set the power supply to provide

0.855V to the input. Press the +10­ dBm button and adjust A2R81 (HIGH

LEVEL COMP) to give 1.1V ±lmV at the output.

Step 16. Set the power supply to provide

-0.228 V to the input. Press the +10­ dBm button and adjust the front panel

CAL control so that O.lOOV is obtain­ ed at the OUTPUT connector with the CAL F ACTOR control set to O.

Set the CAL FACTOR control to

-ldB and +ldB noting the reading at each point. Adjust AIR19 (CAL

FACTOR ADJ) so that the readings are as close to O.OOOV and 0.200V as possible. Be careful when setting the

CAL FACTOR control to be sure that the knob lines up exactly with the panel mark. There might be some re­ sidual difference between the setting of AIR19 to obtain OV and that re­ quired to obtain 0.2V. The correct adjustment in this case will result in equal (and opposite) errors at both ends of the CAL F ACTOR range.

Step 17. Reset the CAL FACTOR knob so that

O.OOOV is read at the OUTPUT con­ nector. Set the 50/75 ohm switch to

75 ohms. The DV M should read

0.276V ±12mV. If not, trouble is indicated in the switch circuit.

Model 1034A

Step 18. For a final check of the calibration of the instrument, check the tracking of the power ranges. Using the power supply, apply the voltages given in the table below and note the readings obtained by the voltmeter connected to the OUTPUT connector. Set the

50/75 ohm switch to 50 ohms.

Step 19. Using the values given in the above table, apply the voltages. With the

A-F button pressed, check the track­ ing of the -40 to +lOdBm meter scale. Tracking should be wi thin

0.5dB down to -30dBm, and within

2dB to -40dBm.

Step 20. Press the CAL button and connect the frequency counter to the CALI­

BRATOR OUTPUT connector. The frequency should measure 30 MHz ±3­

MHz. If not, and it is fairly close, it can be ad justed by sligh tly bending the oscillator coil, AILl, to change the spacing between the turns.

Otherwise, check for out-of-toler­ ance components in the oscillator cir­ cuit.

6-6

Step 21. The purpose of this adjustment is to set the output of the calibrator to

10mW ±1.5%. This constitutes a very high degree of accuracy for a power measurement at 30MHz. According­ ly, the procedure must be performed with great care. If the .proper equip­ ment is not available, do not attempt to make the ad just ment.

Set the precision power supply to

1.414V. Connect the adapter describ­ ed in Section 6.3.1.d to the output of the supply, and connect the Thermal

Converter to the output of the adapt­ er. Read the dc output of the Ther­ mal Converter to a precision of

0.1 %. Reverse the polar ity of the supply and repeat the reading. Re­ cord the average of the two volt­ ages. Turn the calibrator on by pres­ sing the CAL bu tton. Attach the

Thermal Converter to the CAL OUT­

PUT and adjust AIR22 (lOmW OUT­

PUT CAL) so that the converter has the same output voltage as it did when it was connected to the power supply. Reconnect the Converter to the supply through the 50 ohm adapt­ er and check to see that the output is the same as before. If there is signif­ icant difference in the reading before and after the calibrator measure­ ment, repeat the procedure. This last step is important because the Con­ verter has a tendency to drift with changes in temperature.

This completes the calibration procedure.

6.4 TROUBLESHOOTING

In order to localize the source of trouble in an instrument such as the 1034A, it is important to have a detailed working knowledge of the in­ stru ment. Section 4, Electrical Description, should be carefully read and the schematics in

Section 7 should be used. Relevant dc vol tages are shown on the schematics, and are typical of values to be found in normal operation. Data

From the library of WØMTU

-

Model 1034A shown on the schematics was taken with a digi­ tal voltmeter with 10M ohm input impedance.

The front controls were set as follows:

POWER: ON

RANGE:

CALIBRA TION

FACTOR:

CAL

CENTERED (0)

50/75 ohm SWITCH: DIRECT 50 ohms

The detector was connected to the CALIBRA­

TOR OUTPUT and the CAL control set so that the meter read full-scale.

The only significant ac signals present in the instrument are those in the chopper circuit. A timing diagram for those signals is shown in

Figure 6-1.

6.5 SEMICONDUCTOR DEVICES

A variety of semiconductor devices are used in this instrument. The type numbers shown on the schematics are either EIA registered device numbers or manufacturer's numbers. Devices meeting the corresponding specifications can be used for replacement purposes, and can proba­ bly be obtained locally. Individual instruments may have equivalent devices of other manufac­ turers installed, and the type number may not agree with those shown on the schematic dia­ gram or parts list.

6.6 ACCESS TO INTERNAL COMPO­

NENTS

To gain access to the internal components, re­ move the two screws underneath the case and then return the case to an upright position

(panel up). Remove the two large screws at the left and right edges of the panel. These last two screws will be somewhat difficult to turn because they are screwed into elastic nuts.

Pressure should be applied to the screwdriver so that it will not slip and mar the panel.
