Sweep Measurements
Making a Measurement
Step 5. Set up the measurement parameters
You set the output parameters on the MEASURE: SWEEP SETUP screen.
1. Press Meas front-panel key. The MEASURE: SWEEP SETUP screen appears.
In the screen, the upper left area defines the VAR1 information, and the upper
right area defines the VAR1’ information. See Figure 1-8.
2. Set the VAR1 information as shown below:
Drain voltage sweeps from 0 V to 2 V with 20 mV step. The current compliance
is set to 100 mA.
3. Set the VAR1’ information as shown below:
To force the same voltage to the drain and gate, set RATIO = 1 and OFFSET = 0.
Because VAR1’ is defined as follows:
(VAR1’ output) = RATIO × (VAR1 output) + OFFSET
