Thanks for the tip. I've been looking at 300X Waveteks and HP 8640s for a while. Both seem to go for big $$.
My goal is to someday have a reliable RF generator in the 20-50 MHz range where I can dial in a frequency with at least one decimal digit of precision without spending a fortune.
Very handy for aligning vintage TV IFs

The Sencore VA62 comes close with it's 35-50 range.
