Per request on another thread from @peng, here is a list of key parts you will need to use a QuantAsylum 401 or 402 to measure the performance of other electronics:
- BNC loopback cables like these. These might be a bit short if you have larger hands, so may need to adjust length.
- 50 ohm terminators like these.
- While you might build a cleaner cable, I use these to adapt BNC to RCA. I then use my RCA to XLR cables to connect the analyzer to the amps balanced input. Ofc, these are convenient to connect the analyzer outputs to unbalanced inputs too.
- You will need some non-inductive dummy load resistors. If you keep high power testing to short durations (seconds rather than minutes), you can use the ones recommended here.
- The load resistors need a good way to be connected. I use banana jacks like these. I had some around that handle larger gauge wire. I find them more useful than the ones made for smaller speaker cable.
- I use sawtooth banana plugs like these to ensure good connections.
