20 MHz Dual Channel Function / Arbitrary Generator Model 4047B - 1

Data Sheet 20 MHz Dual Channel Function / Arbitrary Generator Model 4047B Features & Benefits n Dual-channel operation with each channel providing the rated amplitude (10 Vpp) over the entire frequency range n Sine arbitrary waveform generator n Bright color display with waveform preview The 4047B Dual Channel Function/Arbitrary Waveform Generator is capable of generating stable and precise sine, square, triangle, pulse, and arbitrary waveforms. CH1 and CH2 outputs are fully independent with individual on/off buttons and can both be varied from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit). The generator provides linear and logarithmic sweep capabilities, AM/FM/PM/FSK/PWM modulation, and a continuously variable DC offset to inject signals directly into circuits at the correct bias level. Separate output amplitude and DC offset amplifiers let you set a large DC offset (e.g. ± 4.99 V) with a small amplitude output signal (e.g. 10 mV). the push of a button n Linear n AM, external modulation capabilities n Gate The 4047B seamlessly integrates with B&K Precision’s waveform editing software WaveXpress, allowing users to generate complex arbitrary waveforms that can be output via the instrument’s 14-bit, 125 MSa/s, 16 kpts arbitrary waveform generator. the phase of both channels with output and DC offset amplifiers allow for small amplitude output signals with large DC offsets n Low-jitter square wave generation for simulating reliable clock signals, generating triggers, or validating serial data buses n USB Dual architecture design The 4047B’s dual architecture, a feature typically only found in more expensive generators, provides all the benefits of a DDS and a true point-by-point arbitrary waveform generator (AWG) combined, without any limitations imposed by either technology. The DDS chip produces standard sine and triangle waveforms with high frequency resolution and at a low cost. The true point-by-point AWG implementation (Fig 2) offers improved signal integrity for arbitrary waveforms by producing significantly less jitter and distortion compared to a DDS-based architecture. Custom arbitrary waveform generation is implemented with a variable clock signal to reproduce each point stored in memory without skipping or repeating data points, a problem typically found in DDS based designs with fixed reference clocks.
