This connector accepts levels in the range of 10 V for the 81150A (5 V for
the 81160A) and is referenced to chassis ground.
A burst always begins and ends at the same point in the waveform. This is
called the start phase. A starting phase of 0 corresponds to the beginning
of the waveform record and 360 corresponds to the end of the waveform
record. The starting phase can be adjusted in the range from 0 to 360 for
sine and arb waveforms and will be 0 for pulse, square and ramp
waveforms.
