Optional square-wave output verification test
This test verifies that the square- wave amplitude, frequency, and duty
cycle functions are within specifications. Note that the measurement
values over the remote interface should be identical to those displayed on
the front panel.

Input capacitance
For the best accuracy, take a zero null measurement with open test leads
to null out the test lead capacitance, before connecting the test leads to
the calibrator.
You should consider programming the U3606A over a remote interface for
this test to avoid round off errors. See the U3606A Programmer's
Reference for more information on remote interface programming.
