3.5.6.0 A10 100-kHz Output Test
1 Connect the 100-kHz output connector on the rear panel to the 50  input of
a scope using coax. (If a 50  input is absent, use the high impedance input
with a 50  coaxial-feedthrough terminator at the scope end of the coax).
2 Verify presence of a 100-kHz undistorted sine wave with at least
2.8 Vp-p amplitude.
QUESTION: Does the scope show a 100-kHz undistorted sine wave
with at least 2.8 Vp-p amplitude?
If Yes: A10 is nominally operational.
If No: Remove power, replace A10, and retest.
