Function Generator 4011A

Product ID: Function Generator 4011A

The B+K Precision Model 4011A Function Generator is a versatile signal source which combines several functions into one unit.

Additionally, the instrument provides the added convenience of a built-in frequency counter. This permits more accurate determination of output frequency than is possible with a simple calibrated dial.

Coarse and fine tuning controls permit precision settability of the output frequency. High stability assures that the output frequency does not drift. 

Specifications:
  • 0.5 Hz to 5 MHz
  • Sine, Square, Triangle, Pulse, & Ramp output
  • Coarse and Fine tuning
  • 4 digit LED display
  • Variable duty cycle
  • Variable DC offset
  • Variable amplitude output plus 20dB attenuator
  • 20Vpp output into open circuit (10Vpp into 50 Ωs)
  • cUL certified
