I know this is a stupid question, but I've been bitten by this before:
Are you SURE you're cabled to the Tx/Rx connector and not Rx2?

Hello All,
I'm having an issue with the transmit power on N210 + WBX not being able
to reach the spec'd 100 mW on the data sheet.
I'm transmitting a PN sequence at a rate of 1.2 Mchips/second. The
values I'm sending to the DAC are +/- 24000 which is a little
bit below the full range of the DAC, but not much. I've set the TX_GAIN
parameter to its maximum value of 25.
I measure the output transmit power with a ladybug powermeter and get
-15 dBm peak power. This is well below the spec of 20 dBm.
Any ideas out there what could be wrong? Does the tx_gain of 25 set all
the gains of the LO, IQ modulator, etc? What is controlled and set by
setting set_tx_gain to 25?
Thanks
Reginald
