Calibration

Module current

First thing after powering-up the (brand new) 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. Wait for command to complete
4. Set power level to 35 dBm
5. Execute VCP command intcal <channel number> 2 35.0
6. Wait for command to complete

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

Output & Reverse power monitoring calibration

Software needs to take measurement points (similar to interlock calibration), to provide proper power measurements via SCPI Interface. Calibration is as follows:

1. Set power level to 0dBm
2. Execute VCP command calpwr <channel number> 1 0.0
3. Disconnect output SMA
4. Execute VCP command calpwr <channel number> 3 0.0
5. Connect SMA and set power level to 35dBm
6. Execute VCP command calpwr <channel number> 2 35.0
7. Disconnect output SMA
8. Execute VCP command calpwr <channel number> 4 35.0

After these steps, you should see following result:
TODO ADD CLI OUTPUT

Input interlock calibration

Input interlock is calibrated at 3dBm. Input power measurement is active regardless of RF switch position, so best chance to use calibration procedure is after enabling output interlock, so RF switch will be disabled.

1. Set output interlock at any level eg. 35 dBm
2. Set power level to 3 dBm
3. Execute VCP command cal <channel number> 0
4. Wait for command to complete

After these steps, you should see following result:
