Thanks
Yah my memory is never what it never was^H^H^H^H^H^H^Hused to be... I have a customer who has an older device that puts out points at effectively 120kHz (low excursion, low step size) but his analog circuitry is getting noise from somewhere on his circuit and I suggested going digital all the way to the amp but found out that all the digital amps are nominally 100kHz... Was originally just planning to tap his digital signalling and converting, and now it sounds feasible again.
While the 35660A doesn't natively have swept sine, you could get something close on it and other similar units by commanding a sweep through the HPIB/GPIB port. Nowadays a usb to GPIB only costs a few bucks so thats also a route.
You can get the 35660A HPIB programming manual here: https://doc.xdevs.com/doc/HP_Agilent...0Reference.pdf
