Re: [Discuss-gnuradio] TX Gain parameter in uhd_siggen_gui

[mleech]

The total gain setting range, and gain step size are set by the hardware.  In most cases, the

  step size is 0.5dB.

Hello everyone,

Im trying to set the TX Gain of USRP device using the following command
while transmitting using uhd_siggen_gui tool:

./uhd_siggen_gui --sine -g <TX_Gain> -f 1013M --amplitude=1.0 -A TX/RX -v

If I set the TX_Gain to non integer or non 0.5 fractional values, it is
getting set to nearest integer or 0.5 fractional values.

For example, if I set TX_Gain to 22.6, it will be set to 22.5 as shown in
gui
Similary, setting TX_Gain to 22.1 will set it to 22, 19.9 will set it to
19.5 etc

But I can set the TX_Gain properly using the gui slider.

Any idea on how to set it properly using command line?

Thanks
