>From the gnuradio as test equipment dept: I finally got around to putting calibration into my Transmission Reflection Vector Analyzer and it was easier than I feared. In fact it was an exciting culmination to the project, as that's what makes a collection of unruly parts work as an accurate instrument. Pics of horizon flat 250Khz to 25Mhz plots are here:

In light of recent discussion, I just lifted the calibration equations from the mcdermott.pdf article on the TAPR VNA, so if he has an error in there I just blindly copied it ;)) --Chuck _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
