The BK Precision model 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.
The instrument generates sine, square, and triangle waveforms with high signal precision and stability, as well as variable output voltages from 0 to 10Vpp into 50ohms (up to 20Vpp into an 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
Triangle / ramp frequency range 0.1Hz to 1MHz
Sine and square frequency range 0.1Hz to 20MHz
Bright colour LCD display with waveform preview
Linear and logarithmic sweep
Adjustable duty cycle
Independent DC offset amplifier design allows large offsets on small amplitude (e.g. 10mV) waveforms
