Functions and Measurements
Making Distortion Measurements
2
Set one source (signal generator) to 300 MHz and the other
source to 301 MHz, for a frequency separation of 1 MHz. Set
the sources equal in amplitude as measured by the analyzer
(in this example, they are set to –5 dBm).
3
Set the analyzer center frequency and span:
Press
Preset
(With
Preset Type
of
Factory
)
Press
Frequency > 300.5 > MHz
Press
Span > 5 > MHz
4
Reduce the RBW until the distortion products are visible:
Press
BW
and
5
Move the signal to the reference level:
Press
Peak Search
Press
Marker > Marker To > Mkr -> Ref Lvl
6
Reduce the RBW until the distortion products are visible:
Press
BW
and
7
Activate the second marker and place it on the peak of the
distortion product(beside the test signal) using the
Next Peak
:
Press
Marker > Mode > Delta
Press
Peak Search > Next Peak
8
Measure the other distortion product:
Press
Marker > Normal
Press
Peak Search > Next Peak
NOTE
The coupler should have a high degree of isolation between the two
input ports so the sources do not intermodulate.
