Rigol DG1022 - Channels: 2, Frequency Maximum: 20 Mhz

Rigol DG1000 series function/arbitrary waveform generators use Direct Digital Synthesis (DDS) technology. They can generate accurate, stable, clean, low distortion signals. Applications Analog Sensor Practical Environment Signals Circuit Function Test IC chip Test Easy to Use Design A variety of display modes Clear graphical interface Support  for  Chinese  and  English menu and input Push-help makes information getting more convenient. File management (support for USB flash device and local storage)   Dual Channel Output, Built-in and Editable Arb Waveform Dual Channel Output: Separately setup the wavefrom and parameter as well as the output state  of two channels. The phases from two channels  could be synchronous while outputting based on  the "AligPha" function from operation menu.   Built-in Waveform Output: The instrument has 48 built-in arbitrary waves (contains DC) which  including common, math, engineering, window function and other common waves.   Editable Arb Waveform: Enable to edit and output a arbitrary wave with 14bits, 4kpts.  In addition, the instrument provides 10 nonvolatile memories for storing custom arbitrary waves. According to Ultrawave, more waves could be edited and saved.     Abundant Modulation Functions, Sweep, Burst Abundant Modulation Functions: Support AM, FM, PM and FSK, the modulated waveforms are  intuitively shown on the screen. It can be used in Education & Training area proverbially.   Sweep: It can generate "sweep" from the start frequency to the stop frequency during appointed sweep time (1 ms ~ 500 s) you specify. Sweeping can be generated by Sine, Square, Ramp or Arbitrary waveforms
