An extract from Making Distortion Measurements with a Spectrum Analyzer, Broadcast Engineering, JAN 1978, pgs. 78-79
" In reference to … article on AM Proof-of-Performance measurements [June 1977). I'd like to take exception to the statement " there is presently no acceptable way to conduct an official proof-of performance with a spectrum analyzer … ".
I'd like to discuss my favorite method. because it is much simpler and faster. It relies on the use of a programmable pocket calculator, such as the HP25. The calculator is programmed to solve the equation for THD …
…
The keystroke listing for the HP25 is given in Figure 1. To use the program, follow the steps in Figure 2. (For a new calculation, go to step 2.) … "
