Measurement Warn. limit. Description
PA V27P LEVEL 24/27 (V) +27 V voltage measurement (Volt).
CSB POWER LEVEL 12/17 (W) CSB output power measurement (Watt).
SBO POWER LEVEL 0.2/0.8 (W) SBO power measurement (Watt).
PH CORR PEAK LEVEL 1/13 Phase correlation peak level measurement.
May indicate that the transmitter is working
outside its dynamic range.
PS1/2 COU/CLR I90/I150 -0.5/1.5 (A) Current consumption in 90/150 Hz amplifi-
ers (Ampere). The TX1 currents is meas-
ured on PS1, the TX2 currents on PS2.
These measurements are listed in the DC
Supplies maintenance parameter window in
the RMM software, but are associated with
the LPA/GPA modules in the automatic
diagnostic functions.
