9-14 Sweep Operation
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 , 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.
Step 3: Set delay.
Set the source delay as follows:
1. Press CONFIG then SOURCE V or SOURCE I depending on the selected source
function.
2. Select DELAY, then press ENTER.
3. Set the delay to the desired value, then press ENTER.
4. Press EXIT to return to normal display.
Step 4: Turn output on.
Press the ON/OFF OUTPUT key to turn the output on (OUTPUT indicator turns on). The
SourceMeter will output the programmed bias level.
