2 1. Frequency Response Adjustments

verify that the power meter indication is -10.00

dBm

fO.10

dB.

If the 100 MHz CAL OUTPUT power level is not within this

tolerance, perform adjustment procedure 19, “CAL OUTPUT

Adjustment”, before continuing with this adjustment procedure.

6. Disconnect the power meter/power sensor from the

speqtrum

analyzer front-panel CAL OUTPUT connector.

7. Press

(2-22)

on the synthesized sweeper. Set the synthesized

sweeper controls as follows:

8. Connect the low-loss microwave test cable to the frequency

synthesizer RF OUTPUT using an APC 3.5 (f) to APC 3.5 (f)

adapter. Connect the power meter/power sensor to the opposite

end of the test cable using a Type N (f) to APC 3.5 (f) adapter.

9. On the synthesized sweeper, press (POWER LEVEL) and adjust the

ENTRY knob for a power meter indication of -15.00

dBm

f0.03

at 21.4 MHz.

10. Disconnect cable 81 (gray/brown) Wl from A6A3J3 (21.4 MHz

OUT) on the

A6A3

Last Converter Assembly. Disconnect the

power sensor from the low-loss microwave test cable, and

connect the test cable to cable 81 (gray/brown)

using an

SMB (m) to SMA (f) adapter. See Figure 3-90 for the location of

A6A3J3 (21.4 MHz OUT).

11. On the spectrum analyzer, key in

8. Verify that the

displayed signal amplitude indicated by the MARKER is -10.00

dBm

f0.40

dB.

If the displayed signal amplitude is not within

this tolerance, perform the following adjustment procedures

as necessary to adjust the overall RF gain of the HP 85662A

IF/Display Section before continuing with this adjustment

procedure:

5. Log Amplifier Adjustments

6. Video Processor Adjustments

10. Step Gain and 18.4 MHz

Local

Oscillator Adjustments

8. 21.4 MHz Bandwidth Filter Adjustments

11. Down/Up Converter Adjustments

12. Disconnect the low-loss microwave test cable from cable 81

(gray/brown) Wl, and reconnect cable 81 (gray/brown)

A6A3J3 (21.4 MHz OUT)

the

A6A3

Last Converter Assembly.

13. Connect the DVM to

AGAlOTPl,

and connect the DVM ground to

A6AlOTP2.

See Figure 3-90 for the location of

AGAlOTPl

and

A6AlOTP2.

14. Adjust

AGAlORl

IO (3.3

GHz

Oscillator Drive, to IE on

A6A4

Second Converter) for a DVM indication of -0.15 ho.01 Vdc. See

Figure 3-90 for the location of

AGAlORl.

15. Connect the DVM to

A6A12TP3

(-9 V), and connect the

DVM ground to

A6A12TP2

(YTX COM) in the RF Section. See

Figure 3-90 for the location of

A6A12TP3

and

A6A12TP2.
