Hi all -- I just became aware of a PTS250-SX51 synthesizer in good condition that's available for $200 plus shipping.
This is an interesting unit -- the standard PTS250 operates from 1 MHz to 250 MHz, but the SX51 modification adds a divide-by-10 module that provides very low phase noise from 1 MHz to 25 MHz in 0.1 Hz steps. The output is a square wave, so requires filtering if you need a sine wave, but the phase noise is lower than just about any other synthesizer that's available surplus, apart from the HP 8662A. If you're interested, contact me off-list and I'll put you in touch with the seller.
