Very useful and intuitive.Still playing with functions.Good packaging, great product.

Excellent! Item received quickly and as stated! Thank you!

It's darn good. The signals are crisp and clear on my analog scope. The amplitude settings seem dead on. The software is a big plus (must), making it very easy to setup and designing arbitrary waveforms which adds some flexibility to the unit. There is third party software available as well for developing your even more arbitrary waveforms. I also liked that you can output to both channels at the same time and with totally different waveforms and frequencies.It also came with a handy TTL interface that plugs into the back of the unit. As stated in an other review the 25 MHz model only puts out a sine wave at that frequency. All other waveforms are limited to around 6 MHz before they start to distort. And at 25 MHz they all looked like a sine wave. The frequency counter seems to work OK but I don't have a calibrated device to measure its accuracy. Three negatives. One the manual is definitely lacking clarity on the operation and functionality of the instrument. Two, the software on the CD was corrupted and it took me nearly a day to find their website, no thanks to the seller in helping me. It took three tries to download the 110 MB file and nearly two hours on the final try as their download speed averaged about 350 kbps (sic). Three, selecting a waveform, frequency, retrieving or storing to memory and selection of other functions is clunky without the software. Some of the buttons have dual functions so you have to push a "shift" button first to access the second function. They also located the on/off switch on the back of the unit. Overall, for under a $100 it will meet my needs, I don't work in a lab or calibrate instruments but as an engineer it does a lot for the money.

Works great. Connection with probes is weak. Have to jiggle it sometimes to get good connection.

Great product! Thanks!
