ESSAGES
The ATi is a precision measuring instrument with fully programmable test
sources. The ATi will, whenever possible, ensure that the programmed
voltage, frequency and DC bias current are present AT THE TERMINALS OF
THE PART UNDER TEST.
This is done by measuring the voltage and current at the terminals of the part
and, if necessary, trimming the test source to establish exactly the required
conditions at the part.
This means that the ATi will automatically compensate for lead resistance and
(if 4-wire Kelvin connections are used) the contact resistance between
connector and the part under test.
ATi basic measurement circuit.
Measured V = Program V
This is very different to commonly used LCR bridges, which have a nominal
impedance in their output to provide short circuit protection for the test signal
generator.
