Equipment Requirements
The 42841A supplies 20 A (1 unit) and 40 A (2 units) DC current bias when
combining the E4980A (test frequency: 20 Hz to 2 MHz) and the 42842A/B test
fixture.
The following equipment is necessary for a system that uses the E4980A and
the bias current source.
— E4980A Precision LCR Meter (with Option 002 Bias Current Interface)
— 42841A Bias Current Source (two units are necessary for 40 A system)
— 42842B Bias Current Test Fixture (only 42842B for 40 A system)
— 16048A Test Lead (with BNC connector)
— Bias Current Interface Cable (furnished with the 42841A)
— 42843A Bias Current Cable (required only for 40 A system)
Confirm that Option 002 Bias Current Interface is installed in the option
slot of the E4980A's rear panel. When option 002 is installed, the 50-pin
connector marked "Option 002: Bias Current Interface" is attached to
either of the two option slots of the rear panel.
Cable Connection
Each instrument needs to be connected using the bias current interface cable,
16048A test lead, and 42843A bias current cable (only for 40 A system). The
cable connection varies depending on the system configuration.
20A System
Connect the E4980A to the 42841A and 42842A as shown in
page 461
1. Connect the UNKNOWN terminal of the E4980A to the TO UNKNOWN
2. Connect the Bias Current Interface connector of the E4980A to the Bias
3. Connect the 42842A test fixture directly to the front panel of the 42841A.
