Section 1: Introduction Series 2400 SourceMeter® Quick Start Guide
Programming example
Table 14 shows a typical command sequence to store and recall readings from the buffer.
Sweep operation
Sweep types
The four available sweep types are linear staircase, logarithmic staircase, custom, and source
memory.
Linear staircase sweep
When the sweep shown in Figure 7 is triggered to start, the output will go from the bias level to the
source level. The bias level is the initial source level prior to the start of the sweep. The output will
then change in equal steps until the stop source level is reached. With trigger delay set to zero, the
time duration at each step is determined by the source delay and the time it takes to perform the
measurement.
With the desired source (V or I) selected, use the follo
win
g menu sequence to set the start, stop
and step source levels:
Press CONFIG > press SWEEP > select TYPE > select
STAIR
After selecting STAIR, you will be prompted to enter the STAR
T, STOP and STEP levels.
