    There's a number of these that look almost identical around with different brand names. This one gives nice looking signals on my oscilloscope. Easy to understand. I have not used the software to do more arbitrary waves, kinda don't want to put unknown software on my computer, will need an isolated virtual machine... But otherwise good price for the grade, gives quick and easy wave forms, very tuneable.

    Got it today, here is an initial assessment: Accuracy; Frequency is nearly spot on as measured against my 10 MHz Rubidium standard (using the standard as the base reference for an Iwatsu SC702 counter); Pk-Pk voltage, offset, duty cycle, etc. are also spot on. Based on observed FFT analysis I would say It easily meets its ±0.8% THD (@ 20Hz to 20 kHz) spec, and sine waves look good out to 25 MHz. Sine wave amplitude is essentially flat out to the full 60 MHz where it's only down about 2 dB. Square wave output is recognizable as such to 25 MHz or so, but by 35 MHz it looks more like a malformed sine wave. Overall Performance; IT meets each of its specs quite handily. The display is very readable, and the UI, with its well-placed 'soft" keys is non-cryptic and simple to master. The PC software (Windows only) is pretty damned good too. The "printed" documentation (supplied as .pdf files on a mini-CD, along with the PC software) could be improved, though its better than a lot of was passes as "English" with a lot of these Asian produced instruments. However the user manual ends abruptly at page 17--the table of contents lists a page 18 that is not there. Mechanical quality, choice of materials and fit and finish are great. I kind of wish it weighed a bit more so it would stay in place better--this is a bit ironic, wishing an instrument weighed more after years of lugging around 40+ pound 'scopes and signal sources...
