Setup to measure the
attenuation and other
problems in our SAT and
CATV distribution system.
Luckily, the Handheld Satcom
Test Source works on battery.

and goes back the other
way whereby the frequen-
cy steps (MHz) and sweep
speed (ms) can be set up
separately. You can also set
up a pause between the two
The Handheld Satcom
Test Source was connected
to the input of the multi-
switch which would then
operate the switch using
the frequency sweep gen-
erator. The spectrum ana-
lyzer mode was activated
on the test equipment and
it was used with the peak-
level hold function activated
in order to be able to read
the results of the frequency
sweeps across the entire
frequency range.
The first attempt failed
because we didn‘t realize
that the spectrum analyzer
needs a certain sampling
period to be able to gener-
ate a spectrum from the sig-
nal. If the signal generator
sweep is too fast, it doesn‘t
allow enough time for the
analyzer to correctly mea-
sure the signal.
So we first had to directly
connect the signal generator
to the analyzer and try a few
different scenarios to deter-
mine the correct parameters
for the frequency sweep.
It quickly became clear
why WORK Microwave in-
