Seems like a lot of money to pay for one. I have been using an HP 3325A for about 25 years and like it very much. I bought it brand new from HP for the company I worked, where I was director of engineering. After I resigned, to pursue greener pastures, they eventually closed down their hardware capability and operations and offered me the entire laboratory and inventory which then I purchased personally. I would recommend you getting the "A" version for about one fifth of the price of that "B" model, unless, you have an overwhelming desire to get the "B" for some special reason. Option 001 provides the high accuracy ovenized reference and it does not look like the one on ebay has that option. Normally they would use a TCXO. Regardless, since you will be using an external reference it really does not matter. The "A" also accepts an external reference and I run my off of a local Rubidium. 73 - Mike

Since I plan to use an external GPS based frequency source, does it matter? I suspect the unit still has a decent ovenized crystal to begin with. Any thoughts from the group? -George Hrysanthopoulos, N2FGX _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts -- No virus found in this incoming message.
