Thanks for all the hints on power meters! Duly noted. As for the 8664, it passes all self tests. I also re-ran self cal now that the frequency reference is good and warm and everything seems to be

Thank you. I’m still recovering from a real nasty flu/cold so everything is going really slowly here. I’m hoping that what I find is helpful to others as I have heard from another group member of

New board should be to you tomorrow. Pete wa2odo

Thank you. All this helps me piece together how the setup works. Right now I am collecting data and once it starts forming a coherent picture I will post it. The firmware plays a big part in this as

The 2nd FFT board arrived, sourced less than 1hr from here, and it is a good board.? All self tests passed.? The 3563A is working!?? On Tue, Mar 19, 2019 at 12:18 PM, morestainless via

Seconded, I have gotten bit by the 2nd or 3rd harmonic even on a good meter. Bird is considered a 5 or 10% meter at best great for tuning bad for accuracy Regards, Stephen Hanselman Datagate Systems,

I live in Ontario Canada and get heavy items shipped to the UPS Store in Ogdensburg NY, sometimes saving as much as $400 shipping! They charge $5 per package for 10 or 15 days, check. It used to be a

Thanks Tom, I will try it! Kevin

Right, I'm finding this out with the Wavetek Pacific Measurements 1038-NS20 and NS201.? I'm still wondering about an Operation and Maintenance Manual with schematics for

G'Day, Yep - I hear ya. At least it can be road freight from the US to you, I'm on a bloody big island! I missed out on a 8673G for $800 just recently :( - I do like those units since they can drive

Glen, Thanks for the previous two messages. Good progress: The machine boots right into XP without problems. Needed to work around passwords on the unit, but that was easy enough using chntpw.

The fan on my HP5335A is 24V, so I guess the modification you mention has already been applied.

Thanks Joe. I will look for another fan with better airflow characteristics. Of course, I could always go for a Papst fan with better noise characteristics.

Jeff, That is the 0.1 Ohm wire wound current sensing resistor.? It looks kind of ratty because of the coating but that is normal.? The reddish-brown stuff I do not know -- could be oxidation from

Hi Peter, The main and FM coil signals pass through the A3 ALC board like this: The FM -? tap to the cavity oscillator is not part of the basic phase lock scheme, it's a spur avoidance fix. You don't

I have also been in the market for a 26GHz SG for a while with no luck. Although I have to say the biggest issue for me has been the sellers not shipping to Canada. I came close to getting a 8673B for
