AD2817C Operation Manual
These are the UNKNOWN Terminals used to connect a four-terminal pair test fixture or test
leads for measuring the device under test.
HD(H ): High current drive
CUR
HS(H ): High potential sense
POT
LS(L ): Low potential sense
POT
LD(L ): Low current drive
CUR
Note: Make sure shielding terminals of Hcur and Lcur are reliably short with low impedance
when the test fixtures or cables used don't come standard with the instrument.
7) Frame terminal
This is the FRAME Terminal which is tied to the instrument's chassis and which can be used
for measurements that require guarding.
3.5 A Tour of Rear Panel
1) IEEE488 (GPIB) interface connector (Optional)
This is the IEEE488 interface connector used when operating on the General Purpose
Interface Bus.
2) RS232C interface connector
This is the RS232C interface connector used when operating on the serial interface.
3) HANDLER interface connector
This is the HANDLER interface connector used when operation with a component handler
to fully automate component testing, sorting, and quality control data processing.
7) Bias voltage monitoring terminal
Internally equipped with adjustable -5V +5V bias voltage, the instrument can monitor
actual bias voltage through DC bias meter.
