The Siglent SDG1025 is a function/arbitrary waveform generator with a 25 MHz maximum output frequency and a 125 MSa/s sample rate. A function generator produces standard shapes such as sine, square and ramp, while the arbitrary mode lets you output custom waveforms for testing circuits and sensors. Key Features 25 MHz maximum output frequency 125 MSa/s sample rate Function and arbitrary waveform output Specifications Brand / model Siglent SDG1025 Max frequency 25 MHz Sample rate 125 MSa/s Shipping dimensions 14.75 x 7.75 in (partial) Shipping weight 2.38 lb SKU 01SDG1025 What's IncludedSiglent SDG1025 waveform generator (1) Ideal ForStudents, hobbyists and technicians who need a bench signal source up to 25 MHz. Frequently Asked QuestionsWhat does the sample rate mean?It is how many points per second the generator's DAC produces. Higher rates allow cleaner high-frequency and arbitrary waveforms.What is an arbitrary waveform?A custom shape you define point by point, such as a recorded sensor signal, rather than a standard sine or square wave.
