Data Sheet 20 MHz DDS Sweep Function Generator with Arb Function Model 4045B Features & Benefits 12-bit, 50 MSa/s, 1k point arbitrary waveform generator Sine and square waveforms up to 20 MHz The model 4045B is a high-performance distortions on non-repetitive waveforms and 20 MHz DDS (direct digital synthesis) function sometimes small details of the waveforms stored Triangle/ramp waveforms up to 2 MHz generator with arbitrary waveform capability. internally will be missing from the output signal. Bright color display with waveform preview Generating stable and precise sine, square, The true arbitrary waveform section generates Linear and logarithmic sweep triangle, and arbitrary waveforms, this instrument point by point waveforms with lower jitter, high AM/FM modulation provides variable output voltages from 0 to 10 resolution, and true representation of the Independent output and DC offset amplifiers Vpp into 50 (up to 20 Vpp into open circuit), required waveform. allow for small amplitude output signals with linear and logarithmic sweep, AM/FM modulation, a built-in counter, and a continuously variable DC Due to the arbitrary waveform capability of large DC offsets offset that allows the output to be injected directly the 4045B, the instrument is able to generate Low-jitter square wave generation into circuits at the correct bias level. Separate low-jitter square waves with greater edge Adjustable duty cycle output amplitude and DC offset amplifiers let you stability. The improved signal integrity allows Output ON/OFF button set a large DC offset (e.g. 4.99 V ) with a these generators to be used for simulating Internal/external triggering small amplitude output signal (e.g. 10 mV), a reliable clock signals, generating triggers, or Gate and burst mode feature typically found in more expensive validating serial data buses. generators. Built-in counter This model is suitable for education and other USB interface The 4045B combines a traditional DDS and a applications that require DDS function SCPI-compliant command set true arbitrary generator in one unit, giving users generators with sweep, modulation, and arbitrary Arbitrary waveform editing software and the benefits of both technologies. Using DDS waveform capabilities. remote control application software provided technology, waveforms can be generated with high Short circuit and overvoltage protection on all frequency resolution at a low price. Due to the inherent limitations of this architecture, not all inputs and outputs points from the waveform memory are used, and points may be skipped at higher frequencies. This leads to significantly more jitter and higher Technical data subject to change www.bkprecision.com B&K Precision Corp. 201420 MHz DDS Sweep Function Generator with Arb Function Model 4045B Front panel Rear panel Output Modulation input Color LCD Dedicated Numeric On/Off Rotary display waveform keys keypad control knob connector button Trigger/counter input connector USB interface Menu function Lin/Log Utility Sync Main keys sweep key key output output Intuitive user interface 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.
