Performance Ve ri fi cation
n. Step the genera
tor, in 10 MHz intervals, through frequencies from 10 MHz
to 90 MHz. 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.
o. In the test r
ecord, enter the greatest result determined within this frequency
range(10MHzto90MHz).
For MDO410
4-3, MDO4054-3, MDO4034-3, and MDO4014-3 Only (steps
p through s)
p. Change th
e frequency range as follows:
Change the stop frequency to 3.1 GHz.
Change the start frequency to 99 MHz.
q. Set the generator to provide a 100 MHz, 0 dBm signal.
r. Step the generator, in 100 MHz intervals, through frequencies from
100 MHz to 2.9 GHz. 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.
s. In the test record, enter the great est result determined within this frequency
range (100 MHz to 2.9 GHz).
For MDO4104-6 and MDO4054-6 Only (steps t through w).
t. Change the frequency range as follows:
C
hange the stop frequency to 6.1 GHz.
Change the start frequency to 99 MHz.
u. Set the generator to provide a 100 MHz, 0 dBm signal.
