Im trying to record about 1 second of a page signal from a cordless phone (later I might need to do this to the DTMF tones as well) so I can play it back and send it to a signal generator. I am using a VSA from Agilent, but Im not sure if it can record a full second with the bandwidths I am using. My span is about 50 kHz and I have a resolution bandwidth of 1kHz (I may change this to 10 or 30 kHz though)... If anyone knows some good hardware/software for recording and playing back signals please let me know.... And some software that can record, decode, and create DTMF signals would be a nice bonus as well. If anyone has any info Id really appreciate it. Thanks.
