It's difficult to resist an invitation to sing. However, since I have been using an HP-8562A Spectrum Analyzer (1987 vintage), an Anritsu MS2601 Spectrum Analyzer (1993 vintage), an HP-4195A Spectrum Analyzer Spectrum Analyzer (really old) and an HP-8572A Receiver System (1994 vintage), I may not have a modern tune. I recently used an Agilent E4440 Spectrum Analyzer, and it was a superb improvement over everything I have. I was especially impressed with it's 26 GHz capability, with a built-in low-noise pre-amp and no need for a harmonic converter. Noise floor was excellent. OTOH, this gadget will cost you north of $100k, which may be too steep to justify for pre-compliance testing. If you have to do it very cheap, you might consider what I use for back-up sanity tests. I have a set of Stoddart/AILTech/Singer/Eaton Series 7 receivers (the NM-17A for 10 kHz to 30 MHz and the NM-37A for 30 MHz to 1 GHz). I bought them both on eBay ($95 & $125); one worked right away, the other needed a fix to the tuning voltage power supply. These give you Peak & Average values, and you can also look for a CCA-7 QP Adapter (think I got that for about $125 too) to give you true QP capability. Can't beat $350 plus a little labor for a pre-compliance setup.
