Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.
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.

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.
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.
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
