Aux Outputs
The Aux Outputs menu programs the rear panel auxiliary D/A outputs.
The outputs may be set to fixed voltages or programmed to sweep. In
addition, the Trigger input can be configured to start scans.
Aux Outputs The four aux outputs on the rear panel are general purpose analog out-
puts which may be programmed by the user. They may be set to fixed
voltages or swept between two voltages. Sweeps may be either linear or
logarithmic (actually exponential).
When sweeping, the outputs change at the sample rate and the sweep
time is the scan length. Sweeps may be 1 Shot (single sweep) or Loop
(repeat) as set by the scan mode. Scan and sample parameters are set
in the Trace Scan menu. Sweeps start and stop with the [START/CONT]
and [PAUSE/RESET] keys. Pausing data acquisition will pause a sweep-
ing output. Resetting the scan will reset a swept output to its start volt-
age. At the end of a single shot sweep, a swept output is held at its stop
value.
Aux Out 1, 2, 3 or 4 Pressing this key selects which aux output's mode, voltage, limits and
offset are adjusted and displayed in this menu. Pressing this key toggles
from 1 through 4 and back to 1.
Fixed, Log or Linear Pressing this key selects the mode for the selected aux output. Each
output may be set to a fixed voltage or swept in log or linear fashion.
Choosing a sweep while a scan is in progress is not allowed.
