Calibration
All Medalist i3070 ICT systems have been tested and calibrated by Agilent
Technologies to ensure that all warranted specifications are met at the
time of shipment.
For ongoing calibration and performance verification:
• ASRU Calibration – Agilent recommends that the ASRU Card in every
module of a Medalist i3070 ICT system be calibrated once every six
months.
This procedure calibrates several voltage references and a resistance
reference on the ASRU Card. These references are then used to
automatically derive all other AutoAdjust correction constants. The
system Diagnostics and AutoAdjust routines constitute an overall system
operational verification. The ASRU calibration is the only calibration
required for the system to continue performing at system specifications.
• System Calibration – In addition to the ASRU calibration, a System
Calibration Service is available for customers who desire more
comprehensive measurements and reporting. System Calibration should
be performed every six months.
This service uses a BT- BASIC program and a traceable voltmeter and
frequency counter to measure a DC voltage source at 20 voltages, an AC
voltage source at nine voltages, a resistor, and two oscillator
frequencies.
These measurements are the foundation for all analog measurements
and digital timing. These same parameters are also measured using the
internal detectors in the testhead, and the measurements are compared
to the standards set by the voltmeter and frequency counter to calibrate
the detectors. A report is generated containing the measurement and
uncertainty data.
A Pin Verification Fixture (PVF, part number E9988- 67901) is required for
the calibration procedure. For detailed information about the requirements
and calibration procedures, refer to Calibration in the Medalist i3070
online help.
