5. If an OFFSET is required,
Press OFFSET (19).
Enter offset value (17).
Press MEAS CONT (13).
NOTE
Do not change the units after offset has been entered.
6. On Level Meter, select desired sideband CHANNEL (10).
7. Tune the Level Meter to the input signal frequency as follows:
If the carrier frequency is to be used to tune the Level Meter to a message channel, press CARRIER (7), FREQ (21 ),
and enter the carrier frequency.
If the tone frequency is to be used to tune the Level Meter to a message channel, press TONE (8), FREQ (21), and
enter the tone frequency.
8. Fine tune the Level Meter to the input signal frequency as follows:
Press 3100HZ (12).
Press COUNTER (11).
Press CNTR->FREQ (14).
Press 400Hz (12).
9. If an offset was entered in step 5, press OFFSET (6).
10. MEASUREMENT/ENTRY display (4) indicates input signal power level. FREQUENCY/ENTRY display (9) indicates
i n p u t signal frequency.
NOTE
Input signal modulation (AM or FM) may cause instability in either display.
11. If MEASUREMENT/ENTRY display is unstable or constantly resets full scale level,
Press AVE (2), If display still unstable, turn AVE off.
NOTE
Use AVE only when necessary because it will decrease the accuracy of this measurement.
Press ENTRY (1).
Press FULL SCALE (20), UP ARROW (16) or DOWN ARROW (15) then MEAS CONT (13) push buttons until
display is stable. Verify OVLD indicator (3) remains off.
NOTE
If OVLD indicator is on or "OL" appears in MEASUREMENT/ENTRY display, increase
full scale level. If "UL" appears in MEASUREMENT/ENTRY display, decrease full
s c a l e level and./or select 100dB RANGE (25).
Repeat step 8.
