Performance Ve ri fi cation
For MDO4104-3,
MDO4054-3, MDO4034-3, and M DO4014-3 Only (steps
p through s)
p. Change the 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, +10 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:
Change the stop frequency to 6.1 GHz.
Change th
e start frequency to 99 MHz.
u. Set the generator to provide a 100 MHz, +10 dBm signal.
v. Step the generator, in 100 MHz intervals, through frequencies from
100 MHz to 5.7 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.
w. In the test record, enter the greatest result determined within this frequency
range (100 MHz to 5.7 GHz).
4. Check at 0 dBm:
a. Set the reference level to 0 dBm as follows: Push the front-panel Ampl
button. Push the side-bezel Ref Level button. Set the Ref Level to 0 dBm.
b. Set the frequency range a s follows:
Push the front-panel Freq/Span button.
Push the side-bezel Start button.
Set the start frequency to 0 Hz.
