High Internal Wattmeter VSWR
The Voltage Standing Wave Ratio (VSWR) read at the Internal Wattmeter is
greater than 3.0. That is, the reflected power reading is more than one fourth
that of the forward power reading. Check for loose RF connections.
High Internal WM Reflected Power
An Internal Wattmeter Reflected Power reading (per subchannel), read dur-
ing FM keying, was above the level indicated by parameter 143 (in Watts).
NOTE: It is the user’s responsibility to assure that this parameter is set to the
correct value based on the desired FM power output. Use RFO FIPS: a 192
SPCQ 64 to see periodic wattmeter readings.
High External Wattmeter VSWR
The Voltage Standing Wave Ratio (VSWR) read at the External Wattmeter is
greater than 3.0. That is the reflected power reading is more than one fourth
that of the forward power reading. Check for loose RF connections.
High External Reflected Power
An External Wattmeter Reflected Power reading (per subchannel), read dur-
ing FM keying, was above the level indicated by parameter 146 (in Watts).
NOTE: It is the user’s responsibility to assure that this parameter is set to the
correct value based on the desired FM power output. Use RFO FIPS: a 192
SPCQ 64 to see periodic wattmeter readings.
Plug-N-Play Error
An error has been detected by the Distributor DSP. This Disable stays active
for approximately 2 seconds when an error on the Plug-N-Play interface
between the RFO and RFB has been detected. The errors that contribute to
this disable are designated by an error source of
ROUTE_MSG_FROM_DIST_DSP in the “A 104" error log. These include;
E_CHECK_COMMAND_FORMAT_ERROR,
E_CONTROL_COMMAND_FORMAT_ERROR,
E_END_OF_COMMAND_ERROR,
E_FREQ_OFFSET_ERROR,
E_INCOMPLETE_FRAME_ERROR,
E_INVALID_COMMAND_TYPE_ERROR,
E_INVALID_MOD_TYPE,
E_INVALID_NEXT_MODULATION_TYPE,
E_INVLAID_NUMBER_OF_SUBCHANNELS,
E_MOD1_INPUT_OVERFLOW_ERROR,
E_MOD2_INPUT_OVERFLOW_ERROR,
E_MODULATION_TYPE_ERROR,
E_START_TIME_ERROR,
E_SYMBOL_DATA_COMMAND_FORMAT_ERROR,
E_UNEXPECTED_SYMBOL_COMMAND_ERROR,
E_WORK_AHEAD_WINDOW_ERROR
