Tests analog bus accuracy, by measuring several analog bus reference voltages
(all nodes from the A10 digital IF). This runs only when selected.
Uses the internal counter to count the A14 fractional-N VCO frequency (120 to
240 MHz) and the divided fractional-N frequency (100 kHz). It requires the
100 kHz signal from A12 and the counter gate signal from A10 to pass.

external connection of a short to PORT 1.
Same as 21, but tests PORT 2.
Tests the front panel knob entry and all A1 front panel keys, as well as the
front panel microprocessor on the A2 assembly. It prompts the user to rotate
the front panel knob, then press each key in an ordered sequence. It continues
to the next prompt only if the current prompt is correctly satisfied.
Similar to 23 above, but the user rotates the front panel knob or presses the
keys in any order. This test displays the command the instrument received.
