Hi, I got this dirt cheap frequency generator, and I believe such an unusual weird thing deserves a review.
Pros:
- Dirt cheap (45 euros including delivery), and yeah it makes a signal as far as I can see
- Built quality is cost effective but not too catastrophic, actually I was expecting something worse
- Good BNC sockets, and good Arduino compatible LCD panel.
- Came with a decent quality USB powerbrick and BNC to crocodile cord, which are always handy to have.
- Frequency, up to 2MHz can be set digit by digit
- Probably enough for basic hobby use
Cons:
- Came raw in a air bubble enveloppe, without retail box, without user manual
- User interface is minimalist and not so convenient
- The rotary buttons are not easy to set, no readout of the offset and amplitude, oscilloscope needed for it
- Provided USB cord was not the correct kind for the device !!! but seems to be ok for an Arduino, at least
- Lack of functions
- Lack of a hi-stability oscillator, seems it runs from a regular quartz
- Square wave shows ripple above 1 MHz
- It's not a Tek or a HP :-p
