A 10-6000MHz Receiver and Signal Separation Modules developed for a Mixed-Signal Automatic Test Equipment System

Abstract

A 10-6000MHz receiver and signal separation test set have been developed by Anritsu-Wiltron Co. and Teradyne Inc.. These modules provide multichannel 0.01-3.0GHz vector network analysis, with expansion capability to 6.0GHz. The power levels of the input signals to the receiver can vary over +13dBm ... -100dBm. The receiver has three selectable power ranges. The receiver Noise Figure is less than 9dB double sideband (DSB), over the 10-6000MHz frequency range. The receiver also provides a wideband IF output. In a mixed-signal test system, the 10-6000MHz signal separation module, which is a 100% solid-state module, provides the interface between the DUT and the receiver. It allows the de-embedding of the DUT S-parameters, and the measurement of DUT nth-order intercept points, noise figure, and P-1dB. The receiver can measure all of the modern digital modulation schemes used in PCS/PCN systems, when coupled with the broad-band DSP capability of the Teradyne A5 system.
