Performance Verification
Push the side-b
ezel Stop button.
Set the stop frequency to 1 MHz.
c. Set the generator to provide a 50 kHz, 0 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. See the following figure.
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).
h. Changethefrequencyrangeasfollows:
Change the stop frequency to 9.2 MHz.
Cha
nge the start frequency to 980 kHz.
i. Set the generator to provide a 1 MHz, 0 dBm signal.
j. Step the generator, in 1 MHz intervals, through frequencies from 1 MHz
to 9 MHz. At each interval, determ ine 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.
k. In the test record, enter the greatest result determined within this frequency
range(1MHzto9MHz).
l. Changethefrequencyrangeasfollows:
Change the stop frequency to 92 MHz.
Change the start frequency to 9.8 MHz.
m. Set the generator to provide a 1 0 MHz, 0 dBm signal.
