General Information

Measurement Accuracy

Any precision measure ment is no bet ter than the calibration of the netw ork analyzer. As a ge neral rule , the sh orter t he time between a c alibr ation and the measurement of a devi ce unde r test (DUT), the more precise the measurement will be, within the limitations of your system. For this r eason, Agilent recom mends that for prec ision measurements you recalibrate your system every few hours, or at a minimum, reverify your system calibration.

The frequency of your requ ir ed calibration will depend on the temperature stability of the location of the network analyzer.

Controlling Multiple Test Sets

Option 001 for the Agilent 851X-serie s test sets will allo w an 8510 to alternately control up to four test sets. While a measurement is proceeding on test set number 1 (equipped with Option 001), a test de vice can be connected to test set number 2, which does not need to be equipped with Option 001. When the measurement on test set number 1 is complete, the 8510 can control test set number 2.

In a standard test set, the 20 MHz IF and control signals are applied directly to the J11 TEST SET INTERCONNECT, which connects to the 8510. Option 001 adds a set of IF switches, control switches, and the J10 TEST SET INTERCONNECT connector. Thi s allows the se lection of 20 MHz t est set IF signals. As shown in Figure 4-5 on page 4-7 test set number 1 can apply its IF to the 8510, or it can swit ch to pass th e IF from test set number 2 through the J10 TEST SET INTERCONNECT to the 8510.

6 Test Set Troubleshooting

Introduction The troubleshooting strategy f or the Agilent 8511B frequency conver ter test

set is a systematic sequence of proc edures. This troubl eshootin g infor mation is used after system-level troubleshooting has pin-pointed the test set as the problem instrument. Use the troubleshooting flowchart Figure 6-2 on

page 6-4 to identify the faulty assembly. The troubleshooting flowcha rt is

keyed to numbered, individual troubleshooting procedures. As you progress through the flowchart, perform the numbered procedure associated with each block. Block diagrams are provided at the end of this chapter to assist in understanding the oper at ion of the test set.

Theory of Operation The RF section of an 8511B frequency converter te st set consists of a

voltage-tun ed osci llator (VT O), a four -wa y po wer spli tte r and fou r samplers . The frequency converter operates within the frequency range of 45 MHz to 50 GHz. Two reference (a1 and a2), and two test (b1 a nd b2) cha nnels a ccept RF input by way of the front panel bulkhead connectors.

The VTO/dri ver produces a harmonic that is 20 MHz away from the RF source frequenc y. The samplers use either the fundamental or a harmonic of the LO with the reference and test RF signals to develop a 20 MHz IF. The IF signals are th en routed to the Agilent 85102 by way of the rear panel connector on the test set.

The LO, generated by the VTO/driver, is phase locked to the source. The phase lock loop includes the following:

• A3 VTO summing amplifier board

• A14 VTO/driver

• A12 a1 reference sampler assembly

• A13 a2 reference sampl er as sembly and the 8510 network analyzer

A microprocessor on the A4 GPIB board controls the samplers, which may be switched either on or of f , de pending on the parameter being measured. The default condition is for all four samplers to be on. This insures that the test set will be usable in the event of a failure of the A4 GPIB board or a failure in the communica tion between the test set and the 8510 display/proce ssor.

The 85102 IF detector controls the VTO/dr iver via the VTO summing amplifie r board. A control voltage is input to the VT O to tune to the corr ect LO frequency.

Agilent 8511B Test Set Operating and Service Manual 6-1

Test Set Troubleshooting

The VTO summing amplifi er board has an output called LENDRA (Low = END of RAnge) that is sent to the Agilent 85102 IF detector ove r the test set interconnect cable . This indicates to the Agilent 85101 displa y processor whether or not the VTO is outside of its nor mal ope rating frequency range. Should the VTO exceed its normal operating range, the network analyzer will respond by displ aying the running error message, message will not be seen in the 8510C. It has been replac ed by

Figure 6-6 Service Adapter Connections

Using the Service Adapter

The service adapter (part number 85102-60210) substitutes for a test set, by connecting the 20 MHz IF signal from the Agilent 85102 back into the amplifie r of the Agilent 85102. This is done to determine if a fault is in the test set or the 85102.

1. Connect the service adapter as shown in Figure 6-6.

2. Press

[RECALL], {MORE}, {FACTORY PRESET}, [MARKER], STIMULUS, [MENU],

[STEP], PARAMETER, [MENU]. Examine each user parameter by pressing

the corresponding softkey to observe the unratioed power level of the user1 through user4 channe ls. The trace s should be flat lin es, quite cl ose to each other, as indicated by the marker value (typically about

28 ±5 dB).

Service Adapter Conclusions

If all the channels look good. The 85102 is working properly. The problem

is most probably with the source or the test set. If one or more channels look bad. The problem is most probably with the

85102. Refer to the Agilent 8510 On-Site Service Manual fo r informati on on troubleshooting the 85102.
