Rigol DG1022A 25MHz Function Arbitrary Waveform Generator Peekaboo Ghost Through the Wall. NEW "A" Version. Has full range of arb sign wave to 25 Mhz Adopt advanced DDS technology; dual channel output; 100 MSa s maximum sampling rate; 14 bits vertical accuracy Output 5 standard waveforms; built in 48 arbitrary waveforms Abundant modulation functions: AM, FM, PM, FSK, linear logarithm sweep and burst Abundant output and input: waveform output; synchronous signal output; external modulation source, external clock reference (10 MHz) input, external trigger input Unique channel coupling and channel copy Built in high precision and wide band counter, the measurement range: 100 mHz ~ 200 MHz (single channel) Standard configuration interfaces: USB Device & USB Host, and support U disc storage Seamlessly interconnect with DS1000 series digital oscilloscope RIGOL DG1000 series function arbitrary waveform generators use Direct Digital Synthesis (DDS) technology. They can generate accurate, stable, clean, low distortion signals. Each channel can create sine, square, ramp, pulse,or noise signals and coordinate with the other channel. These instruments each have 2 channels with the 2nd channel having a lower voltage output. Each DG1000 can output 4055 point arbitrary waves. Dual Channel Output, Built in and Editable Arb Waveform Dual Channel Output: Separately setup the waveform 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. Burst: It can generate pulse sequence for a variety of waveform function, and the waveform could continuously cycle within specific time or apply external gating signal. Channel Coupling and Copy Channel Coupling: Once you setup the base channel and the Frequency Phase deviation of the two channels, the Frequency Phase of the other one will vary with the base channel and will still keep the deviation you have selected. Channel Copy: According to this function, the parameters from one channel could be copied to another channel with no change of the waveform shape. Built in Frequency Counter counter coulde be used to measure these parameters: frequency, period, duty cycle, positive pulse width and negative pulse width within the range of 100 mHz to 200 MHz. Two modes of counter are available: Auto mode: The coupling mode, sensitivity, trigger level and the switch of high frequency reject could be set automatically. Manual mode: DC AC, sensitivity (low, mid, high), trigger level, the switch of high frequency reject could be set manually. Package includes DG1022A, power cord, and Quick Guide. NOTE: No probes or cables are included. Latest firmware and digital manual are available for download on the manufacturer's website.
