Multi-Band Amplifier For Test And Measurement Instruments
US Patent:
7298206, Nov 20, 2007
Filed:
Feb 7, 2006
Appl. No.:
11/349783
Inventors:
John J. Pickerd - Hillsboro OR, US
Thomas F. Lenihan - West Linn OR, US
Thomas F. Lenihan - West Linn OR, US
Assignee:
Tektronix, Inc. - Beaverton OR
International Classification:
H03F 3/68
US Classification:
330126, 330124 R
Abstract:
A multiband amplifier for a test and measurement instrument includes a splitter to split an input signal into split signals, amplifiers, and means for combining and digitizing the amplified signals into a digitized signal. Each amplifier is configured to amplify an associated split signal over an amplifier passband. The amplifier passband of at least one amplifier is different from the amplifier passband of another amplifier.

US Classification:
315 1
Abstract:
Position Lock Trigger apparatus employs oscilloscope circuitry and accompanying control software to provide to a user the capability to trigger an oscilloscope on a selected bit position in a received serial bit stream having a fixed pattern length, using either a synthesized, recovered, or external clock source. The selected trigger position can be moved forward and backward along the serial bit stream by one or more serial bit positions at a time in order to examine the entirety of the fixed pattern length serial bit stream, with or without regard to the actual bit sequences occurring in the serial stream.
