NOTES:
8. Program the desired input to output combination (e.g., IN7 to OUT1).
9. Enable the selected output(s).
10. Drive the selected input with VIN, and measure the -3dB frequency at the selected output (VOUT).
11. Load all outputs with the desired RL.
12. Disable all outputs.
13. Drive all inputs with VIN and measure VOUT at any output; isolation (in dB) = -20log10 (VOUT/VIN).
14. Drive VIN on one input which connects to one output (e.g., IN7 to OUT7).
15. Terminate all other inputs to GND.
16. Enable all outputs.
17. Measure VOUT at any undriven output; crosstalk (in dB) = 20log10 (VOUT/VIN).
18. Terminate one input to GND, and connect that input to a single output (e.g., IN0 to OUT0).
19. Drive the other seven inputs with VIN, and connect these active inputs to the remaining seven outputs.
20. Measure VOUT at the quiescent output; crosstalk (in dB) = 20log10 (VOUT/VIN).
