Sir,

I am running example OFDM tx & rxCode on USRP 2943 . In receiver VI , in CFO Correction dependencies one block "Ramp pattern by samples" is showing error

"This method call node couldnot find its target. The target may have been moved renamed or deleted".

Please specify and locate how to get the asked target?

Thanks & Regards

Hello Everyone, I'd like to measure my experiment data by using two Keithley 2000 which are controlled by Labview software. But I have some problem this labview block diagram, that I wrote, it can run but the sequence of channel changes every time, and both keithley 2000 aren't simultaneous. If who do have any idea to write Labview block diagram better than me, please introduce me. Thank you.
