Greetings Erik,
Congratulations on your handheld SA project! I imagine it will become a very popular product.
I have decades of experience with RF instrumentation and a background in telecommunications engineering standards and design. I own a Tektronix 7L13 spectrum analyzer, HP 8656B RF Generator plus a Signal Hound spectrum analyzer/tracking generator pair. I have written articles regarding my DDS designs for Circuit Cellar and ARRL QEX magazines. I had the good fortune to be in the winning circles of a couple of microcontroller design contests regarding my DDS RF generator projects. Recently I designed a simplistic but inexpensive step attenuator to provide a front end for adapting a popular SDR receiver module to function as a broad coverage spectrum analyzer. The relative portability of your stand alone design that does not require a host PC appeals to me.
Should you select me it would be my pleasure to evaluate your analyzer design and provide you with test results.
