Three-channel--Three-channel function / arbitrary waveform generator is a set of generator, arbitrary waveform generator, pulse generator, four-channel TTL generator, VCO, frequency sweeper, counter and frequency meter, etc. DDS--The instrument uses DDS direct digital synthesis technology to produce accurate, stable and low-distortion output All parameters are calibrated by internal procedures. All software of the instrument is equipped as standard. parameter save--Press and hold the OK key during use, you can quickly save the parameter information currently output by the instrument, and the saved parameters can be automatically loaded at the another boot. 98 groups--Can output up to 98 groups of functions / arbitrary waveforms, including 34 preset waveforms and 64 user-defined waveforms.Four attributes of the signal: frequency, amplitude, offset, and duty cycle can be scanned separately. 100M--100M frequency meter function: It has four measurement methods: frequency measurement, period measurement, positive and negative pulse width measurement, and duty cycle measurement., Manufacturer: Walfront
