rge 3-41/ ADD after the 492P Verification Program:
For Option 42 instruments. Check Power Output at the 110 MHz OUT
mector on Band 1 (</= 0 dBm)
a. Using the flatness data for the instrument being tested/ find the signa"
;h the highest amplitude.
b. Connect a signal generator to the frequency determined in step a and
jer level to -30 dBm.
c. Set the 492/492P Option 42 REFERENCE LEVEL to -30 dBm and RF ATTENUATION
0 dB.
d. Keeping the signal centered with the CENTER FREQUENCY control/ switch
FREQUENCY SPAN/DIV to 0 (the crt FREQ SPAN/DIV will indicate 10 ms).
e. Adjust the CENTER FREQUENCY control of the 492 Option 42 to center the
^gnal displayed on the 7L14.
f. Check that the 110 MHz IF OUT output power is </= 0 dBm.
For Option 42 instruments. Check Power Output at the 110 MHz OUT
Connector on Band 5 (>/= -40 dBm)
a. Using the flatness data for the instrument being tested, find the signal
;h the lowest amplitude on Band 5.
b. Connect a signal generator capable of the frequency determined in
(p a to the 492 Option 42 RF INPUT.
c. Set the signal generator to the frequency determined in step a and
power level to -30 dBm.
