BK Precision 4040B Offers a Three Year Parts and Labor Warranty

The BK Precision 4040B is a versatile sweep function generator, designed with a dual technology architecture combining direct digital synthesis (DDS) and a low-jitter square wave generator. This instrument generates sine, square, and triangle waveforms with high signal precision and stability.

This sweep function generator provides variable output voltages from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit), linear and logarithmic sweep, AM/FM modulation, and a continuously variable DC offset to inject signals directly into circuits at the correct bias level.


  • Sine, square, and triangle/ramp waveform generation
  • Bright color LCD display with waveform preview
  • Linear and logarithmic sweep
  • AM/FM modulation
  • Adjustable duty cycle
  • Independent DC offset amplifier design allows large offsets on small amplitude (e.g. 10 mV) waveforms
  • Store and recall instrument settings
  • Output On/Off button
  • Internal/external triggering
  • Gate and burst mode (4040B only)
  • Built-in counter
  • USB interface with SCPI-compliant command set
  • Short circuit and overvoltage protection on all inputs and outputs
  • Since and square frequency range: 0.01 Hz - 20 MHz
  • Triangle/ramp frequency range: 0.01 Hz - 2 MHz

Included Accessories:

  • Instruction manual on CD
  • Power Cord
  • USB (type A to B) interface cable
  • Certificate of Calibration
