Connect the amplifier or combiner to the Monitor’s input. Connect the
antenna or feeder to the output.
To monitor the RF waveform, connect the forward and reflected power
monitor ports to an appropriate power sensor or meter.
Note: If a power monitor port is not being used, terminate
it with a 50Ω load.
Power/Alarm Connector
Connect the external power supply here. Pin numbers and descriptions
are given in Figure 3 and Figure 5.
Low voltage models (ACM-x-xxxxxL and ACM500-x-xxxxxL) require
+11 to +26 Vdc power @ 0.1 A (nominal +15 Vdc).
Note: Exception: Model ACM-L2-DFDFTL-12SP is a low
voltage model but it requires a +9 to +18 Vdc (12 V nominal) @
0.13 mA. Either terminal (10 or 11) may be connected to DC
input ground, as dictated by the power supply requirements.
High voltage models (ACM-x-xxxxxH and ACM500-x-xxxxxH) require
36 to 72 Vdc (48 V nominal) @ 0.1 A. Either terminal (10 or 11) may be
connected to DC input ground, as dictated by the power supply
requirements.
WARNING
Do not touch the center conductor of the power
monitor ports while RF power is being applied.
CAUTION
The input voltage must be clean and stable. Be sure
that the input voltage does not surge and does not
contain spikes. Failure to comply may result in
permanent damage to the instrument.
CAUTION
The maximum input voltage differential is 72 V. Do
not apply an input voltage differential greater than
72 volts. Failure to comply may result in
permanent damage to the instrument.
