Multi Channel Sweep Measurements

Multi channel sweep measurement is performed as shown below. The source
channel forces staircase sweep voltage or current, and the measurement channel
performs one point measurement at each sweep step. Up to eight channels can be
used for both sweep output and measurement. Both voltage output mode and current
output mode are available for the sweep sources regardless of the output mode of the
primary sweep source.

1. The primary sweep source sets output by the WV or WI commands. And the nth
(n=2 to 8) sweep source sets output by the WNX command.
2. The sweep sources simultaneously start output by a trigger, such as the XE
command. However, if a sweep source sets power compliance or forces
logarithmic sweep current, the sweep sources start output in the order specified
by the n value. Then the first output is forced by the channel set by the WI or
WV command.
3. After the hold time, the sweep sources wait for the delay time.
4. After the delay time, the measurement channel starts measurement. If you use
multiple measurement channels, the channels that use the fixed measurement
ranging mode start measurement simultaneously, then other channels perform
measurement in the order defined in the MM command.
For the Keysight E5270B, note that the high-resolution ADC cannot perform
simultaneous measurement.
