content: What do you think guys, is it worth to get or can you get a new and better one for the same money?I have a signal generator that I make myself but it's nowhere near as advanced as this.

content: Quote from: MarkoAnte on October 25, 2013, 10:33:33 pmWell this Function Generator is nice but nowadays I would rather recommend you a new Chinese one. Mainly because you can get much more functionality out of it. In your price range I think this will suffice.https://www.eevblog.com/forum/testgear/siglent-sdg1025-arbitraryfunction-generator-under-some-tests/https://www.eevblog.com/forum/testgear/siglent-sdg1000-(aka-lecroy-wavestation)-firmware-updates/

content: In the US, they go for about $100. I've never used one, so I can't say it that's worthwhile.

content: It's nice, but I'd get a newer model with much greater frequency range for general use. 600KHz is pretty limiting.

content: [way too much. 100$ max.These machines have problems.They are very difficult to operate. They were supposed to be under computer controlThey also have lithium battery inside. Deleted battery means you loose the installed options.They have pretty unique capabilities though.

content: Welcome to a funny situation.. I'm the seller of this oscilloscope :-DI bought it purely for the pleasure of fixing it. It had a dead power supply - replaced a schotty diode inside and it works now. Price.. well, if we hypotetically start with 100 USD for the unit in USA, add 100 USD for shipping and add value added tax, you get close to the number advertised. And in EU they go for 300+ EUR and shipping.As for what it's worth... don't know. I don't need it. For function generator needs I have Hantek DDS 3x25 which does a lot more than this unit for a fraction of the price, but I like the pure engineering part of the HP unit and I find it easier to use. And it takesa lotof space on the desk.It has some jitter, but otherwise the signal is nice. If you only need up to 600Khz sine and no arbitrary part, then it might be worth the money. The units that have opt 001 (mine doesn't) can produce almost all signals that you might need, but in that case the user interface is really pushing its limits.

content: Function generators do go for a lot of money in the EU. I've sold some low end, basic, old ones for well over £100.
