B&K Precision 4047B Function/Arbitrary Waveform Generator

Overview

The B&K Precision 4047B is a dual-channel function and arbitrary waveform generator designed for laboratory and test applications. It combines the capabilities of a traditional function generator with a true point-by-point 14-bit arbitrary waveform generator, eliminating the limitations of either technology alone. Each channel provides stable, precise waveforms from DC to 20 MHz, with independent output controls and integrated modulation capabilities.

Key Features

• Dual-channel operation with independent on/off controls
• Sine, square, triangle, pulse, and arbitrary waveforms up to 20 MHz
• 14-bit, 125 MSa/s arbitrary waveform generator with 16K-point memory
• Output range: 0 to 10 Vpp into 50 ohms (up to 20 Vpp open circuit)
• Linear and logarithmic sweep capabilities
• AM, FM, PM, FSK, and PWM modulation (internal or external)
• Gate and burst mode operation
• Low-jitter square wave generation for clock signals and serial data validation
• Continuously variable DC offset (±4.99 V)
• USB interface with SCPI-compliant command set
• Internal/external triggering
