Generating High Frequencies, Single or Multiple Tones, and Other Deterministic Waveforms Using the HP94K/HP93K Tester

Disclosed is a method that uses the current HP94/HP93K tester to test stimulus frequencies of up to 16.4 GHz (~32.8GB/s). Benefits include using existing, inexpensive testers to lower production costs.

Background

The current 94K (with RF capabilities) tests up to 6Ghz.The 93K uses the Agilent rack and stack Yukon system, which tests up to a speed of 3.125GB/S, one channel at a time. It contains a switch matrix to mux the device under test (DUT) inputs and outputs to the rack equipment. The equipment consists of a PRBS box for generation and detection, a digital communication analyzer (DCA), reference and synchronization clocks, a modulation system to jitter the stimulus, and the 12.5 rack and stack to test the 10G devices.

The above rack can cost millions of dollars; in addition, using the GPIB for controlling and reading the equipment requires very expensive TIUs to be able to interface with the DUT.

General Description

The disclosed method uses the HP94/HP93K tester to test stimulus frequencies of up to 16.4 GHz (~32.8GB/s) as well as various signals—from sinusoidal, to PRBS, to arbitrary waveforms. It also enables the analysis of components at the output of the DUT of up to 13MHz (~26MHz), with the ability to calibrate and eliminate adverse effects during transmission and receiving, all without using expensive RF capabilities required to test high freque...
