NOTE
The calibrator signal changes phase during trigger
holdoff.
This does not affect the accuracy of the
calibrator signai that is present during a sweep.
However, if the CALIBRATOR signal is used with
other instruments, the sweep of the instrument
must be shut off. If it is not, the signal will appear
to jitter and will give false (low) frequency counts.
The sweep of the instrument is easily shut off by
setting TRIGGER MODE to SGL SEQ.

and provides a versatile ground connection.
