Performance Verification
v. Step the genera
tor, in 100 M Hz intervals, through frequencies from
100 M Hz to 5.7 GHz. At each interval, determine the test result as follows:
Note the readi
ng on the power meter and the readout for the Reference
marker on the oscilloscope.
Calculate t
he difference between the two readings. This is the test
result.
w. In the test r
ecord, enter the greatest result determined within this frequency
range (100 MHz to 5.7 GHz).
5. Check at –1
5dBm:
a. Set the reference level to –15 dBm as follows: Push the front-panel
Ampl butt
on. Push the side-bezel Ref Level button. Set the Ref Level
to –15 dBm.
b. Set the f
requency range as follows:
Push the front-panel Freq/Span button.
Push the side-bezel Start button.
Set the start frequency to 0 Hz.
Push the side-bezel Stop button.
Set the stop frequency to 1 MHz.
c. Set t
he generator to provide a 50 kHz, –15 dBm signal.
d. At 50 kHz, determine the test result as follows:
Note the reading on the power meter and the readout for the Reference
marker on the oscilloscope.
Calculate the difference between the two readings. This is the test
result.
e. In the test record, enter the greatest result deter mined at this frequency
(50 kHz).
f. Step the generator, in 100 kHz intervals, through frequencies from
100 kHz to 900 kHz. At each interval, determine the test result as follows:
Note the reading on the power meter and the readout for the Reference
marker on the oscilloscope.
Calculate the difference between the two readings. This is the test
result.
g. In the test record, enter the greatest result determined within this frequency
range (100 kHz – 900 kHz).
