Keithley Intros Arbitrary Waveform/Function Generator
Arbitrary waveform generator.
Cleveland, OH — Keithley Instruments, Inc. has introduced its Model 3390 50MHz Arbitrary Waveform/Function Generator, with high waveform resolution. The unit is a flexible, easy-to-use programmable signal generator with advanced function, pulse, and arbitrary waveform capabilities. Superior signal integrity, faster rise and fall times, lower noise, and greater waveform memory combine to provide high quality output signals.
According to the company, high resolution waveforms are supported by four times the waveform memory of any competitive waveform generator on the market.
Among its many useful features, the Model 3390 includes: 50MHz maximum sine wave frequency; 25MHz pulse frequency with 10ns minimum width; arbitrary waveform generator with 256k-point, 14-bit resolution; built-in function generator capability including sine, square, triangle, noise, DC, etc.; precision pulses and square waves with fast (<10ns) rise/fall times; built-in 10MHz external time base for multiple unit synchronization; built-in AM, FM, PM, FSK, PWM modulation; frequency sweep and burst capability; LXI Class C compliant Ethernet, TMC compliant USB and standard GPIB interfaces; and digital pattern output port and control capabilities. The instrument Arbitrary Waveform/Function Generator is said to have the fastest repetition rates for waveform generators in its class — at least 2X faster than the competition. In addition to high sine wave frequency, increased speed provides a variety of application benefits, such as higher repetition rates for square, triangle, ramp, and arbitrary waveforms, faster rise times in pulse and point-to-point arbitrary waveform transition, higher modulation frequencies, and more realistic noise simulation.
The unit has four times the memory capability of competing offerings, with 256,000 points, compared to competitive waveform generators that only offer 8,000 or 64,000. More points translate to a smoother waveform or a waveform four times as long with the same resolution.
The Model 3390 can perform six different key functions in one package, saving valuable rack space and eliminating the need to purchase separate instruments for function generation, pulse generation, waveform generation, pattern generation, noise generation, and modulation. It has a 10MHz standard external reference clock port that gives users the ability to easily synchronize multiple 3390 units or other equipment, simplifying unit-to-unit synchronization.
The instrument has a number of built-in standard waveforms and also allows users to define and store their own custom waveforms. It includes the company's KiWAVE Software, a waveform creation utility for creating custom arbitrary waveforms and managing waveform memory. KiWAVE lets users view waveforms in real units and perform waveform editing.
