Hello Tom, Not sure if someone said this already, the Wavecrest units can sample your data. Up to 40K samples per second continuous according to their literature, via GPIB. Their PC application software (VISI) has a scope mode where you can make this data visible just like on a two-channel sampling scope. If you are lucky, you can pick one up for ~$500 on Ebay, or rent one. bye, Said In a message dated 4/10/2009 16:13:59 Pacific Daylight Time, eliocor@gmail.com writes: > > ---------- Forwarded message ---------- > From: "Tom Van Baak" <tvb@LeapSecond.com> > To: "Discussion of precise time and frequency measurement" < > time-nuts@febo.com> > Date: Fri, 10 Apr 2009 13:38:55 -0700 > Subject: [time-nuts] OT: 10 MHz data capture, help > I'd like to do a continuous capture of the bits, for up to tens of > minutes, into a PC.
