Operating Instruction
Operator’s
Check
The operator’s check is supplied to allow the operator to make a quick check
of the coaxial transfer switch prior to use or if a failure is suspected.
CAUTION
ESD exceeding the level specified in
Table 9
or RF power applied is greater
than the maximum specified as in
Table 4
may cause permanent damage to
the device.
Description
The coaxial transfer switch is connected to a network analyzer configured
for the s-parameter measurement. The network analyzer may be set to sweep
over the whole or selected frequency range of the switch to be verified. The
s-parameters measurement is the best way to determine if the switch is
working properly.
