Description
BK4040B 20 MHz DDS Sweep Function Generator
Sine and square frequency range 0.01 Hz – 20 MHz
Triangle/ramp frequency range 0.01 Hz – 2 MHz
B&K 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. This instrument generates sine, square, and triangle waveforms with high signal precision and stability. The 4040B 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.
Features of the BK4040B
- Sine, square, and triangle/ramp waveform generation
- Bright colour 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
Intuitive User Interface
The BK4040B is set apart from the rest by its ease of use.
Easily change all waveform parameters using the intuitive menu-driven front panel keypad, rotary control knob, and large color LCD display that shows a preview of the output waveform. Convenient waveform and range selection buttons let users make quick and precise adjustments to the output signal.
Versatile Tools
The BK4040b offers both AM and FM modulation along with linear/logarithmic sweep and built-in counter capabilities. Internal and external sources can be used for triggering and modulating the signal.
Easy PC Connectivity
The function generators can be programmed remotely via the USB (virtual COM) interface using SCPI commands. B&K Precision also offers application software (available for download at www.bkprecision.com) that provides virtual front panel emulation, allowing users to remotely control their instrument without the need for programming.
