Overview
Models 4014B and 4040B are versatile sweep function generators, designed with a dual technology architecture combining direct digital synthesis (DDS) and a low-jitter square wave generator. These instruments generate sine, square, and triangle waveforms with high signal precision and stability. Both models provide 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
