Measurements Using DC source

Measurements Using DC source
This section describes a practical measurement example of the E4980A/AL
using the DC source. The list sweep is used for this measurement. The basic
procedure flow to perform this measurement is the same as the Basic
Measurement Procedure described previously.
When option 001 is not installed, the DC source cannot be used.
The DC source has a 45mA current-supply capability. If you want to limit
the base current of the transistor, insert a resistor between the DC source
and the base.

Measurement
Conditions
Step 1. Turn the E4980A/AL ON.
Step 2. Set up the E4980A/AL measurement conditions by filling in the fields on the
MEAS DISPLAY page.
1. Move to the FUNC field using the cursor keys and select R-X.
Step 3. Press the [Meas Setup] key to set the following measurement conditions in
each field of the LIST SWEEP SETUP page.
1. Set the list sweep parameter to DC SRC[V].
2. Enter the level of the sweep point.
Step 4. Connect the test fixture to the E4980A/AL as shown in
16047E Direct Couple Test Fixture (general purpose) is used for this
measurement.
Step 5. Perform the correction. To compensate the Keysight 16047E's residuals and
strays, an OPEN/SHORT correction is required.
1. Leave the 16047E in an OPEN condition as shown in
2. Press the [Meas Setup] key and the CORRECTION softkey.
3. Move to the OPEN field using the cursor keys and press the MEAS OPEN
4. Press the ON softkey to enable an OPEN correction.
5. Connect a shorting bar to the Keysight 16047E to set up the SHORT
