Hi group...

I'm in the process of working on one of two Ailtech/Eaton AIL-460 Signal Generators that I have, and I need an RF level "standard" for both that purpose, and to calibrate an HP-411A RF millivolt meter.

I'm aware that the 7L13 50Mhz calibrator signal is stated as -30dBm into 50 ohms, but how accurate is that spec...?

Also, does anyone have a fair amount of experience with the AIL 460 SG, or that has one for some comparisons and queries...?

Thanks for reading this...73...Jordan VE6ZT

It should be as accurate as the 7L13 instrument itself. Note however that given their age, each 7L13 today most likely requires full calibration to achieve the factory specs. I had to calibrate mine, including the calibrator level. Fortunately the procedure is not very difficult although it takes time and effort.

HTH,
