extracting portion of a recorded waveform

Hi. I'm using NI RF Phase-Coherent Multi-Channel Version 1.1. I'm recording and then playing back a signal. Is there a way that I could just playback a portion of the recorded waveform? For example, capturing a portion in the "middle" of the entire duration of the waveform? Thank you.

Re: extracting portion of a recorded waveform

Hi NathanDave,

This is possible, but not currently supported by the NI RF Mulrichannel software.I will add this as a possible feature for the next version.

 

One way to workaround this and still use this software without any modifications would be to create a new binary data file containing just the portion of data you wish to regenerate, and then replacing the original data file with this new file.

Re: extracting portion of a recorded waveform

Hi. Sorry for bothering you with another question. How can I edit the binary file? Can you recommend some software applications that can do this? Because at this moment, I can only edit the excel file of the two channels. I don't know how to handle/edit the binary file. Thank you.

Hello Nathan,

 

For editing any binary file you may use a hex editor program.  The steps will be different on each program but you would just copy the number of bytes you woud like starting from a certain point and then create a new file and paste those bytes and save.
