Product Highlights

DATAQ Instruments' DI-770 Series Oscilloscope products provide hardware and software to support high speed data acquisition in a manner that is both price- and performance-competitive with stand-alone digital storage oscilloscopes. Two hardware versions are offered, one sampling at a maximum rate of 25 MHz and another at 100 MHz. Both hardware products are supported by WinDaq/Scope software. DI-770 hardware with supplied WinDaq/Scope software really offer five virtual instruments in one: An oscilloscope, voltmeter, spectrum analyzer, data logger, and a function/arbitrary waveform generator. These features, combined into one instrument, offer unprecedented instrumentation power, speed, and flexibility. The DI-770 oscilloscope offers two analog input channels with 8-, 12-, 14-, or 16-bit resolution depending upon sample rate. Each channel provides a 200mV to 80V full scale input range, a 128K sample record buffer, and supports a sampling rate per channel of up to 100 MHz, depending upon the model.

The DI-770 oscilloscope is provided with two 1:1 and 10:1 switchable oscilloscope probes. The product is provided in the same form factor as other DATAQ Instruments troubleshooting instruments, like the model DI-730. Package size measures L 9" × W 7.29" × H 1.52".

Flexible Performance

Used by itself or in combination with other DATAQ Instruments products, the DI-770 oscilloscope replaces conventional digital storage oscilloscopes (DSOs) that lack the DI-770's small size and direct computer compatibility. Add to this the instrument's ability to operate incrementally as a voltmeter, data logger, spectrum analyzer, and a function/arbitrary waveform generator and the instrument is solidly positioned as an alternative to multiple, bulky conventional instruments. In field maintenance and troubleshooting applications size matters, and the DI-770 oscilloscope is the smallest multi-instrument solution available.

5 Virtual Instruments in One

DI-770 Hardware coupled with the provided WinDaq/Scope Software essentially offers 5 virtual instruments: an Oscilloscope, Voltmeter, Data Logger, Spectrum Analyzer, and Function/Arbitrary Waveform Generator.

Easy to Connect and Use

The DI-770 oscilloscope features a USB 2.0 interface that is backward compatible with USB 1.1. Power is derived directly through the USB cable so no external power supply is required.

Compact Size

Measuring only L 9" × W 7.29" × H 1.52"—the same size as our DI-720 and DI-730 Series instruments—the DI-770 oscilloscope is the smallest multi-instrument solution for field maintenance and troubleshooting applications.


The DI-770 oscilloscope can be directly mounted on any DI-720 or DI-730 Series instrument to create a system combination capable of addressing the entire industrial spectrum of voltages and frequencies.

High Resolution

8-, 12-, 14-, or 16-bit measurement resolution is possible depending upon sample rate.
