Keithley Instruments, Cleveland, OH, has introduced the Model 3390 50- MHz arbitrary waveform/function generator, a programmable signal generator with function, pulse, and arbitrary waveform capabilities. Features include 50-MHz maximum sine wave frequency, 25 MHz pulse frequency with 10-nanosecod minimum width, and 256K, 14-bit resolution arbitrary waveform generation. The built-in function generator includes capabilities such as sine, square, triangle, noise, and DC. The unit incorporates LXI Class C-compliant Ethernet, with USB and standard GPIB interfaces, as well as built-in AM, FM, PM, FSK, and PWM modulation. Pulses and square waves feature less than 10-nanosecond rise/fall times. A 10-MHz external time base is included for multiple-unit synchronization. The unit includes KiWAVE software, a waveform creation utility for creating custom arbitrary waveforms and managing waveform memory. It enables users to view waveforms in real units and perform waveform editing.
