Re: [HP-Agilent-KI eysight-equipment] FM Tuner alignment generator?..

Panasonic and Meguro make?some great units. I have a Panasonic - which in some communities?is kind of a standard for this - and I hate to do this, but if people would know how good these are at aligning?modern tuners they'd go for much higher prices than relatively famous?units such as an ST1000A or other older units. These Panasonic units are very accurate, rugged, modern, and have a very comprehensive set of features for this work. Furthemore, they allow you to align the very best tuners to well beyond what an older unit would allow you to.?
I am not aware of HP units that can be as good at this specific work as some of the Panasonic models I know. The Panasonic, Meguro, and some of the other makes mentioned cater very specifically and with the right set of features to the FM tuner techs. I don't think you should be focusing?on HP for this duty. I am a hardcore fan of HP instrumentation and I use a Panasonic for this work. There may be HP units I am not aware of, but once I got this, I never looked back.?
The other units I typically employ for this are an Audio Precision system with a Lynx interface that allows for very accurate and live distortion readings through ARTA (these two constitute my standard equipment for all my audio work). Using both THD and FFT on a tuner can give a plethora of information about the optimal adjustment for a given alignment step. A lot of that information would be inaccessible without this equipment.?
With the combination?above, with some of the best tuners, adjustments to well beyond 0.03% are possible.?
