Alignment
Audio Matrix
Equipment
2 channel 20MHz oscilloscope
Audio signal generator providing 0dBu at 1KHz.
Audio Level Meter
Module Extenders (optional equipment)
Only the insertion gain of each output channel of the router can be
adjusted.
Insertion Gain
The matrix modules have been factory set for unity gain when driving into
a 10K
Ω
load so it is unlikely that the modules will need to be adjusted
during installation. In the event of the module requiring alignment in the
field, such as due t, component replacement etc., simply adjust the output
level to match the input level using a 1kHz (approx) tone at a level of about
0dBu.
Serial Digital Video Matrix
Equipment
TV Picture monitor with serial inputs or D/A converters for the relevant
TV standard.
TV waveform generator with a smooth full field picture or preferably one
showing the split field pathological test for the relevant TV standard.
Length of video cable or a cable clone set to 250M (820.25 ft) of 8281 or
PSF1/2 cable, optional.
