B&K Precision 4050B Dual-Channel Waveform Generators

B&K Precision 4050B Dual-Channel Function/Arbitrary Waveform Generators can generate stable and precise sine, square, triangle, pulse, and arbitrary waveforms with an easy-to-read color display and intuitive interface numeric keypad. These instruments feature linear/logarithmic sweep, built-in counter, extensive modulation and triggering capabilities, a continuously variable DC offset, and a high-performance 14-bit, 150MSa/s arbitrary waveform generator. Waveform editing software is included to create custom arbitrary waveforms easily, or any of 196 built-in predefined arbitrary waveforms can be used. More than 1000 user-defined 16k point arbitrary waveforms can be saved to the instrument. The included LabVIEW™ drivers allow users to load and save .csv or .txt file data directly into the arb memory without using waveform editing software.

Extensive modulation capabilities include:

      • Amplitude and frequency modulation (AM/FM)
      • Double sideband amplitude modulation (DSB AM)
      • Amplitude and frequency shift keying (ASK/FSK)
      • Phase modulation (PM)
      • Phase shift keying (PSK)
      • Pulse width modulation

The standard external 10MHz reference clock input and output allows users to synchronize their instrument with another generator. The generators also offer powerful channel copy, track and combine functionality, and the phase of both output channels can be synchronized conveniently with the push of a button.
