Cannot query XB-300 power output ADC during transmission #527

Open Gigithecode opened 6 years ago

Gigithecode commented 6 years ago

On a bladeRF 115K + xb 300 Command line xb 300 pwr doesn't work while transmitting ("device busy") otherwise the resullting wording in NOT appropriate and really misleading... "PA output power: " shouldn't be better something like "PA Detector Voltage (dBmV):" ? or, better, an output based from an extension of the following table from SE2605L_203009E specs VDET P OUT = +30 dBm 0.90 1.00 1.15 V P OUT = +26 dBm 0.65 0.73 0.82 V P OUT = 5 dB 0.30 0.33 0.36 V

@Gigithecode I clarified the title, I hope you don't mind.

To summarize what we need to do:

  1. Determine why we can't pass command/control to the XB-300 during transmission. (I think I know why, but can we fix it?)
  2. The minimum voltage (0.3 V) corresponds to approximately +5 dBm output power. This is misleading when nothing is being transmitted. Can we add a correction factor, or use a threshold below which we simply report "zero" output power?

No problem!
