Module current

First thing after powering-up the RF Channel module is setting proper bias current for amplifier power stage. In order to execute calibration, type in VCP Console:

biascal <channel number> <desired current>
where current (for most use cases) is 50 mA

After completing steps listed above you should see something like this:

Output interlock calibration

In order to allow software to properly calculate comparator reference for desired power level, we need to take measurement samples at two different power levels (23 dBm and 35 dBm). Procedure is as simple as:

  1. Set power level to 23 dBm
  2. Execute VCP command intcal <channel number> 1 23.0
  3. Set power level to 35 dBm
  4. Execute VCP command intcal <channel number> 2 35.0

After completing steps listed above you should see something like this:
