BK Precision – Test and Measurement Products

“Specializing in the design and manufacture of high quality, cost-effective test and measurement products for over 50 years”

“Since its founding in 1951, B+K Precision Corporation has built a reputation for excellence in the design and manufacture of high-quality, reliable and cost-effective test and measurement products. B+K Precision is the fourth most recognized instrument brand in the United States. ”

The BK Precision model 4078 Dual Channel Arbitrary Waveform Generator uses direct digital synthesis to generate waveforms up to 400,000 points.

arbitrary waveform generator

An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resulting waveforms can be injected into a device under test and analyzed as they progress through it, confirming the proper operation of the device or pinpointing a fault in it.
