## Overview

The Siglent SDG5082 is a professional-grade 80MHz dual-channel function and arbitrary waveform generator featuring DDS technology, 2ppm frequency stability, and ultra-low phase noise (-116dBc/Hz). Its 4.3" TFT-LCD display provides clear waveform visualization, while USB connectivity and remote control support enable seamless integration with Siglent oscilloscopes and PC software. Ideal for electronic design, sensor simulation, and functional testing, this device combines precision, versatility, and reliability in a compact form factor.

## Description

The Siglent SDG5082 is an 80MHz two-channel combined function generator and arbitrary waveform generator for use with Siglent digital storage oscilloscopes (sold separately) in electronic design, sensor simulation, and functional testing. It has a real-time sample rate of 500MS/s with 1μHz frequency resolution and 14 bits vertical resolution. The function generator uses Direct Digital Synthesis (DDS) output for precise frequency generation. The arbitrary waveform generator produces sine, square, ramp, pulse, gaussian white noise, and DC output signals. Additional specifications include 2ppm high frequency stability and -116dBc/Hz low-phase noise. The unit has a 4.3" color TFT-LCD (480 x 272 pixels) for waveform output display. The USB interface connects to compatible PCs using supplied software. It meets Ingress Protection IP20 standard for resistance to water and dust and meets European Standard (EN) and International Electrotechnical Commission (IEC) 61010 safety standards.SpecificationsBandwidth80MHzChannelsTwoDisplay4.3" TFT-LCD (480 x 272 pixels)Power100 to 240V power adapterWeight2.8kgDimensions (H x W x D)105 x 261 x 344 mmH is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Siglent manufactures electronics test and measurement instruments for research and development, production-line testing, and electronic field service applications.

    the software worked to quickly both capture and edit / create custom arbitrary wave forms that were easy to load back to the SDG
  

*by D***T on Reviewed in the United States on November 20, 2014*

I am setting up a test bench after a multi-decade hiatus in the study of things electronic.  One item that I needed was a function generator, and also wanted the ability to create arbitrary wave forms.  This unit works as advertised, and I was making use of it in very short order.  This is a feature-rich signal generator, especially for the price point.  I'm not making money with these devices, so I had to keep my expenses "reasonable."  (everyone has their own thresholds :-)  )Pros ... this unit works within specification as advertised and is functional out of the box.  The added software makes the generation of arbitrary wave forms a fairly simple task.  It has a number of "built in" wave forms ready for your use, as well.Cons...  as with many products from China, the manuals could use an edit by an English as First Language technical writer.  In addition, the software did not come with the VISA dll files necessary for the software to function.  A little research got me to a free download of these from the National Instruments website, and the software then would load and function.  The other thing is that I run Win 7 64, and the included software needed to be set up in compatibility mode to work.  (Interestingly, with the Siglent CML1102CML oscilloscope that I purchased after this generator, the VISA information was included on the CD.)Once set up, the software worked to quickly both capture and edit / create custom arbitrary wave forms that were easy to load back to the SDG5082.Overall, excellent value for the money, and the generator will be used for many years to come.

    Rock Solid AWG
  

*by C***R on Reviewed in the United States on September 8, 2014*

Dave Jones found rust on his until while tearing it down.. I didn't have this issue nor have many others. I don't know how he ended up with the rusted chassis? This unit is rock solid. It was pretty obvious how to use it out of the box. I was really worried I was going to regret buying this over the Rigol unit. I have no tried building my own arbitrary waveforms so I can't speak to that. General use is easy, the signal is clean on my new tek scope and the frequency seems to be spot on. The display looks dim in videos and while it's not the brightest thing ever I find it very readable in the fairly bright shop.
