Building A Tracking Generator 

I got a TinySA Ultra to play with. I got an ADE-25 mixer to try this video out and used a MAX2870 signal gen set to 977MHz as Kerry said and it works well. I don't have nice equipment as many of viewers and Kerry have so my tinkering is at a hobby level. Great instructional video!

Kerry thx for taking the time and sharing this information. I didn't know that a TG could be this easy and so low cost. It certainly adds a major dimension to what an SA can do with regard to characterizing through crkts. Now I'll get on the hunt for suitable components to build a TG. Again thx for sharing.

Nice job, this is genuinely inspiring for me -- I have a crazy plan that might involve about 13 minicircuits modules; seeing that they work as well as they say they do makes it seem less risky!

Nice simple solution Kerry especially if you're just doing occasional characterizations. Surprisingly flat output; makes me appreciate even more having a built-in TG and the ability to normalize before measuring. Well done!

Hi Kerry, I have a Tektronix 494p and would love to utilize a tracking generator like this to test my homemade antennas for RC video transmitting. The frequencies I’m interesting in testing are @ 5.8ghz. Do you think something like this could work for my purposes? Thanks for the great content!

hi kerry kerry i am impressed with your explanation but i don't understand the linking of the 1st lo from my analyzer i have an advantest tr 4135 could this work too thank you

hi ken this is dennis.I have an old wiltron sweep generator. i found out that it is out of calibration. When i key in 50 mhz both the scope and spectrum analyzer will read 74mhz. do you know anything on how to calibrate it. thanks dennis

Muy interesante amigo..!! Yo tengo un HP141T con plug in de 10khz a 1.25ghz sera que puedo construir un tracking generator compatible para este analizador de espectro????

Hello, I have a Rhode and Schwarz Fsl3 spectrum analyzer. and when I send a 0dBm signal to its input, the tracking signal is distorted at the beginning of the band, from 9khz to around 100khz, and tends towards 0dBm by increasing the frequency. I don't have any diagram. Can you direct me to the function that could be faulty? Thanks a lot.

I might have missed this-but you talk about the signal gen being phase-locked to the analyser but I don't see how you have done that. It looks to be a free-running signal source. Please show me where I'm missing out here.

Why would you add a tracking generator to a tracking generator? Since when was the HP 8566B a tracking generator - I thought it was a spectrum analyzer. Maybe I'm just missing something totally and misreading your dsescription?

Are you familiar with the TG6000 made for the HP8566B and other SA's? I bought one several years ago and it has been excellent. The dynamic range is ~85dB but considering the 8566B does not have a TG, it certainly adds new utility to an otherwise outstanding SA. The TG6000 is currently produced product by DS Instruments; cost is well under $1K ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tQDoe9e0s1o.html
