7.3.2.2 REC Interval
PIM-P Analyzers record measurements whenever the
Record button is pushed. Multiple pushes create multiple,
corresponding individual log files. If measurements need
to be analyzed over a longer of time, PIM-P Analyzers can
record log data automatically by setting the REC interval
to a value other than “OFF”, which will record data
automatically at the interval entered. When RF power is
activated in the Field mode screen pressing the Record once starts recording, the
second push stops recording. The Status Indicator field will show the REC symbol
lit during recording. If RF power is switched off during recording, data logging
stops.
REC Intervals: 1s, 2s, 5s, 10s, 20s, 30s, 1m, 2m, 5m, 10m, 15m, 30m,
1h, 2h, 5h, 12h, 24h and “OFF”,
Default: OFF
7.3.2.3 Filter BW
Advanced Mode Only.
Default filter bandwidth of the PIM-P receiver is 1.2 kHz;
which is the optimized setting for best performance. Increasing
bandwidth opens the receiver, allowing to “see” if signals are
present close to the receiving signal frequencies. If Change of
Filter Bandwidth effects all IM frequencies that fall in the
receiving range of the PIM-P. Decreasing the filter bandwidth allows to eliminate
unwanted signals very close to the receiving signal frequencies. Possible Filter BW
settings are:
Filer BW: 300Hz, 600Hz, 1.2kHz, 2.4kHz,5kHz,10kHz, 12kHz, 15kHz ,25kHz
50kHz
Default:1.2 KHz
Note: Varying filter bandwidth influences the amount of RF energy measured by the
PIM-P receiver.
Wider Filter BW measurement values increase (lower negative number),
Tighter Filter BW measurement values decrease (higher negative numbers).
