HP 461A Final Response Tests

I've gone through the performance tests and here is my version of the final acceptance tests. The last thing I needed to look at was the frequency response. I could do the low frequency stuff using the HP 400F but the high frequency part required a RF Voltmeter. I don't have that but I do have an RF signal generator and a spectrum analyzer. Check out how I worked out that I'm happy iwht the 461A and the repair.

Very interesting, thanks! You still have the HP461? Beside the flat response, could you show us the harmonics rejection levels? And the noise floor? thanks!

I still do have that unit - I'll put it on the list of things to do but feel free to bug me if I don't follow through.
