MetroQ MTQ1515 DDS Signal / Function Generator with Counter with USB- 15 Mhz Arbitrary Waveform Generator adopts large scale FPGA integrated circuit and high-speed MCU microprocessor. The internal circuit adopts the active crystal oscillator as the benchmark. So the signal stability is greatly strengthened. Using Dual-channel DDS signal and TTL electric level output to generate precise, stable, low distortion output signal. includes Sine wave, Square wave, Triangle wave, Saw tooth wave, Pulse wave, white noise, user-defined waveform etc. each channel can be independently set the parameters. With linear sweep(Max. up to 999.9s) and logarithmic frequency sweep functions. Has a frequency measurement, period measurement, positive and negative pulse width measurement and counting function. Storage feature: You can store 99 groups instrument state parameters set by the user, can be called up to Reproduce. The frequency output of Sine wave can be up to 15MHz. 200MSa/s sampling rate. It has 60 positions for saving user-defined waveform. Waveform Length of each one is 2048 and vertical resolution is 14 bits This Signal Generator is the ideal instrument for electronic engineering, laboratories, production lines, teaching and scientific research. Key features: Uses advanced FPGA and a speedy microprocessor. Ensures signals are steady and reliable with active crystal oscillator. Generates a wide range of waveforms, including sine, square, triangle, sawtooth, and pulse waves. Features two independent channels to set different parameters. Measures frequency, period, pulse width, and even counts pulses. You can store up to 99 different setups and 60 custom waveforms. And each with a resolution of 2048 points and 14-bit detail.
