Testing the Reflectometer RM44 and RM50
Generator levels
It is assumed that the synthesizer section (synthesizer1) associated with the reflectometer to be tested
is OK.
Loosen cable W514A (GEN -> coupler unit) or W512 (GEN -> attenuator) at both ends and screw
off at the generator output GEN.
Connect the generator output to the spectrum analyzer using the K-cable (ZVA40) or V-cable
(ZVA50).
Set the ZVA to the CW sweep mode.
Set the frequencies listed in the table.
Set the power listed in the table.
