The results must fulfill the following limits:
Note: In later Phoenix versions the notch calibration might not be applicable anymore.
TX power level tuning
RH-37 supports GMSK and EDGE mode for the Power amplifier. Therefore, the power
level tuning must be carried out for both modes in each band.
It is strongly recommended to use the
Phoenix <Auto-Tune>
capability. The functional-
ity of it is described in chapter “
Fully automatic Calibration, Tuning & Measurement
by Phoenix <Auto-Tune>”
.
It is strongly recommended to use TXP as external trigger for all TX tunings. External trig-
gering gives the following advantages:
• trigger for spectrum analyzer (gated sweep)
• trigger for oscilloscope
• trigger for power meter (avoid exchanging of attenuator and getting better accu-
racy in power measurements)
Nevertheless, manual tuning is described below. It has to be carried out in all three bands
and both modes (EDGE and GMSK).
