PowerMeter

class tam.PowerMeter(ipaddr, port)

calibrate(ctl_id, src_device, device_id, src_pwr, startf, stopf, stepf)

Run a calibration on the selected power detector.

Parameters:

• ctl_id (int) – The detector to calibrate (either 0 or 1)

• src_device (str) – The signal source being used to carry out the calibration. This will be one of: ‘SMHU58’, ‘DSG815’ or ‘DDSGEN’.

• device_id (str) – The id of the calibrating signal source.

• src_pwr (float) – The signal power level used for the calibration (in dBm).

• startf (float) – The calibration start frequency in MHz.

• stopf (float) – The calibration stop frequency in MHz.

• stepf (float) – The frequency step for each calibration point in MHz.

Note

Calibration is a long running process and is synchronous. For this reason the ~rpyc~ synchronous request timeout is disabled for the duration of the calibration.

property chan: int

Get or set the power meter channel to use.

initialize()

Initialize the power meter state.

measure_pwr(freq, apply_correction=False)

Measure the channel signal power.

Parameters:

• freq (float) – The signal frequency in MHz.

• apply_correction (bool) – If this is True then insertion loss correction (if available) will be applied to the measured signal power.

Returns:

The signal power in dBm.
