Editing and synthesis of power supply output waveform
In the development and verification process of electronic products, signal generators are often utilized to generate test signals or simulate signals for testing and specification/ function verification of the designed electronic circuit. Common test signals include Sine, Square, Triangle, Ramp, Pulse, Noise, Burst waveform and communications modulation waveform etc. Signal generators provide a variety of test waveforms that can meet a variety of applications, however, signal generators generally only provide 10Vp-p/ 25VA signal output, which cannot meet the requirement of the test signals for high-voltage outputs. Using a signal generator with a GW Instek ASR series power source can provide high-voltage output test signals.
Select AC power output mode (AC-INT Mode) or AC/DC power output mode (AC+DC-INT Mode) of ASR-Series to set AC power output or AC&DC power output; select External AC signal source mode( AC-EXT Mode) or External AC/DC signal source mode (AC+DC-EXT Mode) to use the ASR series as an amplifier, which can directly amplify and output external input signals by the ASR series; select External AC signal superimposition mode (AC -ADD Mode) or External AC/DC signal superimposition mode (AC+DC-ADD Mode) to superimpose and output the external input signals and the voltage signals set by the ASR series. Signal generator+ASR-3000 provides a maximum signal output of 400Vrms/±570Vdc/999.9Hz, and signal generator+ASR-2000 provides a maximum signal output of 350Vrms/±500Vdc/999.9Hz.
In addition, the editing and synthesis of power waveforms can also be realized via the PC Software provided by the ASR series. PC Software’s built-in Arbitrary Waveform Function (ARB) editing function can directly save the edited test waveforms to a USB flash drive and upload it to the ASR series or directly transmit them to the ASR series through a communications interface (USB, LAN, RS-232 or GPIB) for the output to the DUT. The ARB editing screen has a canvas with a horizontal axis of 4096 points (0~4095) and a vertical axis of 16bits resolution (-32767 ~ +32767) for users to edit user-defined arbitrary waveforms.
Editing methods include 1) Draw hand-drawn pen mode; 2) Line straight line mode; 3) Insert function mode Sine, Square, Triangle, Exponential Rise, Exponential Fall, Noise, DC and Harmonic Synthesizer; 4) Oscilloscope directly imports waveforms(GDS-3000 only); 5) Mathematical synthesis waveform modes: Add, Subtract, Multiply. The examples in the figures below are i). Sine waveform mathematically synthesized 1/4 amplitude & 5 times frequency Sine waveform; ii) Sinc waveform starting from 90 degrees and lasting 1024 points to connect with two cycles of hand-drawn waveforms; connect the Triangle waveform starting from 0 degree and last for 1024 points; and finally connect the Noise waveform.
