Test Instrumentation

Multimeter, Oscilloscopes and Logic Analyzers.

hp or  Hewlett-Packard  started as a T&M Firm.  Agilent  Technologies continued the Instrumentation Products after hp became a computer company.  Now Keysight Technologies is the new name for the Instrumentation Division. Agilent now is a Life Sciences company..

Keysight Technologies - Test and Measurement

“From a small garage in Palo Alto, California, to employees around the world serving customers in 110 countries, Agilent has a long history of innovation and leadership in the communications, electronics, semiconductor, test and measurement, life sciences and chemical analysis industries.”

Keysight Technologies – Test and Measurement

The company founded by William “Bill” Redington Hewlett and Dave Packard was know as Hewlett-Packard Company or HP. This was a Test and Measurement company. First popular product was a precision audio oscillator, the Model HP200A.

Later Computer and Printer products divisions retained the brand and firm and Agilent was spun off for for the Test and Measurement and other non-computer product line.

A high precision 6 ½ digit Digital Multimeter with dual measurement displays, 11 measurement functions and 10 math functions at high accuracy.

A scanner card, which carries 16 V-Channels and 2 I-Channels, to facilitate the measurements of multiple-test points on either a device or multiple devices all at a press of a button.

The GDM-8261 can be used as a semi-auto ATE System to increase the throughput of manufacturing test or as a data logger to perform long term monitoring or characterization of a DUT.
