I'm borrowing a power meter and frequency county from work, an Agilent 53148A. While it's slow at work I wanted to make some measurements and align my ham radio stuff. It's last calibration was in May 08. I let it warm up for several hours, and it has the oven option. My 10 Ghz LO is 10,224 Mhz and it was 70 hz off. Not a big deal for my application. I found the manual and figured out how to choose an external reference on the 53148. I just wanted to ask the group if the Thunderbolt would be more accurate than the internal reference? I want to think it is but my link to the thunderbolt spec sheet is no longer valid. This weekend I'll measure it again using the tBolt as a reference.

Well, sure, it's more accurate than the undisciplined OCXO in the counter, that's the idea behind the Thunderbolt. :) -- john, KE5FX > -----Original Message----- > From: time-nuts-bounces@febo.com [mailto:time-nuts-bounces@febo.com]On > Behalf Of n3izn@aol.com > Sent: Friday, December 19, 2008 12:07 PM > To: time-nuts@febo.com > Subject: [time-nuts] Agilent 53148A, thunderbolt and my 10 Ghz LO > > > I'm borrowing a power meter and frequency county from work, an > Agilent 53148A.
