4-wire sense measurement support

improved accuracy when calibrating

calibrators with 4 wire sense output.

Remote switched GUARD

Terminal

IEEE controlled Manual Switch

IEEE control of GUARD terminal helps fully

automate calibration without need for

manual switching.

Read rate

High Speed - 150 readings/sec @

5.5 digit resolution

High Speed - 100,000

reading/sec @ 4.5 digit

resolution

High read rates are useful for some ATE

applications where accuracy is not of high

priority.

Calibration technique

Individual Function and Range

calibration.

Artifact Calibration & Individual

Function and Range

calibration.

Both techniques have their merits. 8508A

and associated calibration technique

provides full results traceability. ‘As found’

data is difficult to determine using 3458/HFL

‘artifact’ calibration.

Artifact calibration provides a low cost

solution for adjustment.
