DC Bias Current Isolation
Functional Description
When the instrument is equipped with Option 001 (Power/DC Bias Enhance), it
supports DC bias settings up to 40V. The DC bias current actually applied to
the DUT can be checked using the IDC monitor.
The DC bias current isolation feature is intended to prevent DC current from
affecting the measurement circuit. To turn on/off this feature, use the DCI ISO
field.
For information on the maximum DC bias current with the DC bias current
isolation feature ON or OFF, see "Maximum DC bias current" in
Chapter 11 "Specifications and Supplemental Information"
When the DC bias current isolation feature is OFF and the DC bias current
applied to the DUT exceeds the maximum level, turn this feature ON. If a DC
bias current exceeding the maximum level is applied to the DUT, the
instrument will fail to return correct measurements.
The DC bias current isolation feature affects measurement accuracy. For
more information, see "Relative measurement accuracy with bias current
isolation" in
Information"
To set up the DC bias current isolation feature:
Step 1. Press [Meas Setup].
Step 2. Using the cursor keys, select the DCI ISO field.
Step 3. Use the following softkeys:
