Hi Derek,

That makes sense, yeah. Thanks!

 Hi everyone,

 I seem to be having issues with the B210 transmitting at an incredibly
 low power.

 I seem to be getting a 60db difference at the receiver (spectrum
 analyzer) between the B210 and N210 with perfectly identically configured
 transmissions using the simple uhd "tx_waveform" example program.

 Has anyone experienced such an issue. I have two B210s that seem to be
 acting the same way.

 Thanks in advance.

 Best Regards,
 Jonathan

2018-02-12 Thread Derek Kozel via USRP-users 
Hello Jonathan,

The gain setting in the USRPs are indexed from minimum gain. On most this
means a gain of 0 is actually an attenuation of the signal. The N210's gain
range is based on what amplifiers and attenuators are on the daughterboard
that is installed. The ranges aren't calibrated to be aligned across
different USRP products so what you are seeing is completely normal.

The total gain-control range on the B2xx family is larger (80dB) than on 
the cards used on X3xxx, N2xx, etc (typically 30.5dB)


Try larger gain values on the B210, like 40 or 50dB.

Hi Jeff,

Thanks for the response.

In both cases a gain of 20dB.

Best,
Jonathan

[USRP-users] USRP B210 TX-Issues

2018-02-09 Thread Jonathan B via USRP-users 
Hi everyone,

I seem to be having issues with the B210 transmitting at an incredibly low
power.

I seem to be getting a 60db difference at the receiver (spectrum analyzer)
between the B210 and N210 with perfectly identically configured
transmissions using the simple uhd "tx_waveform" example program.

Has anyone experienced such an issue. I have two B210s that seem to be
acting the same way.

Thanks in advance.

Best Regards,
Jonathan
