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
