RS PRO AFG-21225 True Dual Channel Arbitrary Waveform Function Generator


RS PRO AFG-21225 is a base-level dual-channel arbitrary function generator which offers superior functions in its class. The two channels are similarly equipped in order to to accommodate dual-signal applications such as differential signalling or IQ modulation. They can be used in either independent or correlated (Couple, Tracking, Phase) configuration. There are four ways the AFG-21225 can generate customised arbitrary waveforms: editing waveform via PC software; point-by-point editing on the panel; loading CSV file; loading captured waveform from RS Pro IDS Series oscilloscopes. The AFG-21225 has a 3.5 inch LCD which displays the operation information, including the true waveform presented at the output. User friendliness and outstanding cost-performance make the AFG-21225 an instrument of choice not only for practical considerations but also for capabilities which can accelerate the development process.

Features and Benefits


• Wide frequency ranges from 1 μHz - 25 MHz (sine wave)
• 1 μHz resolution in full range
• Built-in standard 120 MSa/s, 10 bit, 4 Kpts arbitrary function for both channels
• True dual-channel output - CH2 provides same characteristics as CH1
• Dual-channel supports Couple, Tracking, Phase operations
• 1% - 99% adjustable duty cycle for square waveform
• User-friendly interface for easy parameter setting and parameter display
• Built-in standard AM/FM/PM/FSK/SUM/Sweep/Burst and Frequency Counter
• USB host/device interface for remote control

Applications


• Power supply/transformer simulations
• Traditional/motor power
• Laboratory and educational research
• Pulse signal as trigger or synchronisation
• Automotive electronics
