5-2 Pulse Mode Operation (Model 2430 only) 2400 Series SourceMeter
®
User’s Manual
Overview
NOTE The Pulse Mode is only available for the Model 2430. The documentation in this
section does not apply to the Models 2400, 2410, 2425, and 2440.
While in the Pulse Mode, the Model 2430 can output one or more pulses. A pulse is
formed by turning the output on for a period of time, and then turning the output off (0V or
0A). A single pulse period is shown in Figure 5-1.
The Model 2430 can output current pulses up to 10.5A at 105V or voltage pulses up to
105V at 10.5A. Pulse output polarity can be positive or negative. While in the fixed source
mode, the output will alternate between the set pulse level and zero (0V or 0A). When per-
forming a sweep, the output will alternate between each sweep step/point and zero. See
Section 10 for details on sweep operation.
A pulse reading is only performed while the output is on. When the output is off (0V or
0A), a reading is not performed. For remote operation, the pulse reading can be disabled.
Auto and manual ohms measurements can be performed while in the Pulse Mode. Also,
offset-compensated ohms is available as a math function (FCTN). However, ohms source
readback cannot be enabled in Pulse Mode.
