Equipment:
Signal Generator
.............................
HP 8656B
Procedure:
1. Set the Signal Generator as follows:
Frequency
.........................................
70 MHz
Amplitude
........................................
28.0 mV
2
0.3 mV
NOTE
For 53348 instruments equipped with Option 060, set Signal Generator
amplitude to 40.0mV
2
0.4 mV. Terminate the unused Channel A and B
rear inputs with 50R loads.
2. Set the 5334B as follows:
FUNCTION
................................
FREQ B
SENS (blue key)
..............................
ON
INPUT B SENS Control
................
MAX
INPUT B 50R
..................................
ON
GATE TIME
...................................
1 Second
INPUT B SLOPE
...........................
OFF (positive)
3. Connect the Signal Generator output to the 5334B Input B. Connect Time Base as shown in F i p r c 5-9.
4. Adjust AIR131 (CH B) for a 5334B front panel display of 70.000 000 MHz -+ 4 Hz
at both the positive and
negative slope settings.
5. Decrement the Signal Generator amplitude by 3 mV rms.
6. Adjust AIR131 (CH B) for a 5334B front panel display of 70.000 000 MHz
2
4 Hz at both the positive and
negative slope settings. If this adjustment is not possible because the signal level has dropped below thc
Counter's sensitivity limit, go to step 10. Otherwise continue on to step 7.
7. Set the Signal Generator frequency to 104 MHz.
8. Adjust AIR131 (CH B) for a 5334B front panel display of 104.000 000 MHz
4 Hz at both the posilive and
negative slope settings. If this adjustment is not possible, go to step 10. Otherwise continue on
to
stcp 9.
9. Set the Signal Generator freqency to 70 MHz and repeat steps 5 through 9 until adjustment is no longcr pos-
sible and this loop is exited from step 6 or 8.
