This link shows someone's tracking generator incorporating such a device

The key to success in making a tracking generator with good dynamic range is to isolate the spec an SALO

output from the mixer.  In the absence of a PMI it can be done with amplifiers and attenuators.

The PMI I have for my TG is HP P/N 0960-0638.  I hope it will be ok.
