User’s Manual Sweep Operation 10-17
WARNING Hazardous voltages (>30V rms) can appear on the selected INPUT/
OUTPUT LO terminal when performing fast pulse sweep operations.
To eliminate this shock hazard, connect the LO terminal to earth
ground. If using the front panel terminals, ground the front panel LO
terminal. If using the rear panel terminals, ground the rear panel LO
terminal. The ground connection can be made at the chassis ground
screw on the rear panel or to a known safety earth ground.
Performing a linear staircase sweep
Step 1: Configure source-measure functions.
Configure the SourceMeter for the desired source-measure operations as follows:
1. Select the desired source function by pressing SOURCE V or SOURCE I.
2. Set the source level and compliance limit to the desired values.
3. Press MEAS V or MEAS I to select the desired measurement function, then choose
the desired measurement range.
See Section 3, “Basic Source-Measure Operation,” for more information.
The source level you set becomes the bias level for the sweep. When turned on, the output
will maintain this bias level until the sweep is started. Typically, 0V or 0A is used as the
bias level.
If using a fixed measurement range, make sure it can accommodate every measurement
point in the sweep. Otherwise, use autoranging.
Step 2: Configure sweep.
Configure the sweep as follows:
1. Press CONFIG then SWEEP.
2. Select TYPE, then press ENTER.
3. Select STAIR, then press ENTER.
4. At the prompts, enter the desired START, STOP, and STEP values.
5. From the CONFIGURE SWEEPS menu, select SWEEP COUNT, press ENTER,
then choose FINITE or INFINITE as desired.
6. Again from the CONFIGURE SWEEPS menu, choose SOURCE RANGING,
press ENTER, then select BEST FIXED, AUTO RANGE, or FIXED as
appropriate.
7. Press EXIT to return to normal display.
