Channel Power Monitor (CPM) Measurements

Figure 42 Channel Power Monitor
The CPM evaluates and monitors LMR systems by checking the key elements of
the transmission path in real time and alerting users of degraded performance
or failures.
Note: The number of channels the CPM can monitor is dependent on
the number and type of RF sensors connected to the system.
The CPM can be used to measure:

Forward Power on multiple channels

Reflected Power on multiple channels

Match Measurements on multiple channels

User Inputs X 3 (NO or NC)
Alarms can be set for the following conditions:

Forward Power, min and max

VSWR, min and max

Measurement procedure

The only configuration options for the CPM are for alarms, push to talk, and user
inputs. See CPM Configuration Menu Options.

Note: Each channel menu item is repeated for all 16 channels. User
input menu items are repeated for all three user inputs.
Channel X Enabled —
and the results will be displayed in the Readings Menu. When disabled, the
channel is not measured.
Channel X VSWR Alarm —
are: Disabled, 1.25, 1.50, 1.75, and 2.00.
Channel X Forward Power Alarm —
power alarm. Enter the power level for the alarm. Enter a zero to disable the
power alarm.
