Moseley SL9003Q 602-12016 Revision G
3.2 Preliminary Bench Tests
It is best to perform back-to-back tests of the entire system while the user has both
Transmitter and Receiver at the same location, prior to installation at the site. Digital
STL's have different parameters for system checks than analog STL's.
Back-to-back bench testing is a good way to familiarize the user with the SL9003Q
Discrete Audio and Composite systems. Also, the user will gain greater confidence in
the configuration and likely save a few trips to the transmitter if the actual
interconnecting equipment (such as the remote control equipment or stereo generator
for the composite system) can be tested at this time as well.
Figures 3-3 and 3-4 show a typical setup for bench testing a complete Discrete Audio
and Composite system respectively.
Caution
■ Always operate the transmitter terminated into a proper 50 ohm load.
■ Always attenuate the signal into the receiver to less than 3000 microvolts.
(Failure to observe the above precautions can cause the transmitter final
amplifier to be destroyed or the receiver preamplifier to be damaged)
■ Avoid excessive pressure on the audio adjustment potentiometers
located on the back panels of the audio encoder/decoder modules.
