[time-nuts] GPIB counter logging / plotting software?

[Dan Rae]

  I am working on 400 - 500 MHz DDS clocks for an amateur radio project 
and would like to record over gpib and plot the relative frequency 
drifts over time of different versions of the oscillator from a cold 
start.  I have Racal 1992 and -hp- 5345 counters available, themselves 
driven from gps.  I have the prologix USB thingy.

Does anyone know of any software that will enable me to do this, without 
spending lots of money?
