Rigol DG822 Function Generator

The DG822 is a 25MHz, 2CH Function Generator with a maximum sampling rate of 125MSa/s. The Rigol DG800 series offers a user-friendly and high-performance function/arbitrary waveform generator solution at a very attractive price. Each instrument provides many functions including; function generator, arbitrary waveform generator, noise source, pulse generator, harmonics generator, analogue / digital modulator and frequency counter. Any Rigol DG800 series function/arbitrary waveform generator would be a valuable asset in any home, business or education laboratory.

  1. Graham S

    Versatile piece of kit. Good value for money
    A very useful piece of kit to have on your workbench that doesn’t take up too much room. Has many sophisticated options that I will never use but does incorporate a very useful frequency counter.
    Check the spec. to ensure maximum input voltage (on counter) and maximum available output amplitudes are OK for your application typically +/- 2.5V (on frequency counter) and similar on generator outputs but this does depend on the output Z selected can get double that.

    Touch screen is sensitive enough but can also use in combination with rotary button and the two arrow keys.

    One down side is that you cannot reduce the number of on screen digits following the decimal point.
    Eg. frequency of 1kHz is displayed as kHz.
    Effectively you could set all these digits to display a frequency but the acuuracy would be very suspect and why would you.

    Great to use, easy no brainer generator
    Lovely piece of equipment, just does exactly what it states on the box!. Sensible price, great delivery.
