  1. I just acquired an HP 8640B and now I'd like to get rid of my HP 606A but I
    need to go below 500 KHz. I wonder if anyone has had any experience with
    the HP 11710A or B that they'd care to comment on. I'd also like to know if
    there's any other reasonably priced LF sig gen that's stable and has a
    calibrated output that I should consider as $150.00 for an HP 11710 seems
    kind of high when you can find HP 8640Bs for around $200.

    You should be able to find a copy of the HP 650 series generator on Ebay or
    at a local surplus store or hamfest. They cover 10 Hz to 10 Mhz, and a
    calibrated attenuator. Good instrument.

    I say, the boy is so stupid that he tried to make a back up copy of his
    hard drive on the Xerox machine!
