power sweep in gain mode

[ojnas]

In transmission_main_example.py there is the following code:

if not power_mode:
        #power cannot be changed in gain mode
        power_range = [0]

so that power sweep is not possible in gain mode. However, the power_dbm parameter in the SI section of eqpt_config.json still sets the power out from the transceiver and I think sweeping this power can be useful also in gain mode so I would propose to remove the above limitation.
