Abstract
An automated test and calibration system based on a planar multijunction thermal voltage converter and a modular electronic instrumentation platform has been developed. Proposed measurement and calibration technique can be used to characterize ac amplitude measurement characteristics of high-resolution (24-bit) ADC based sampling devices and has been tested up to 100 kHz. Especially, a two-channel high-speed, high-resolution oscilloscope device has been internally self-calibrated and extensively characterized in the frequency range of 50 Hz-100 kHz. Furthermore, two ADCs, i.e. NI PXI 5922 and NI PXI 4461 have been compared with reference standard (Swerlein algorithm) to investigate their precision in rms amplitude measurement of ac signals.
