This I know is off topic but I need some help. I am receiving a HP 8640B signal
generator, and have heard of some nightmares concerning the tuning cavity it
uses. I'm wondering what I need to look for on this, and if any lubrication
ought to be done before using it too much, etc. My other generators are all
digitally tuned and do not have this so I'm wondering what I may be in for if I
see any problems. I bought this generator for my calibration bench to be driven
off my GPS standard. I am also going to calibrate the internal OCXO with the
standard before I use the standard to discipline it getting it as close as
possible. I think the varactor in the OCXO only allows 1 Hz tuning? If anyone
could, please e-mail me about these off the list. It would be much appreciated.
Also, I'm getting in a Struthers wattmeter with the slugs. This is the one with
the slanted face and has the SWR reading. Have any used these and what are your
thoughts on them? Let me know off the list.
