Something else that was sent to me by the vendor is a small piece of software that will allow you to setup the generator much faster using the USB connection. As the file is above the size allowed by the forum I decided to upload it to my shared drive:
https://drive.google.com/file/d/0BwoyXU6sOGKLSTdEYi1nLXg4QTg/view?usp=sharing

The rar file contains both the manual and the application.

It's most likely using the AD9831 and AD9834 (for the 25 MHz version).

They're okish, if it's properly filtered but the amplitude will probably vary a lot based on the set frequency.

Anyone care to post some pictures of the board?

Thanks for the sweep instructions, and for the manual. All working now...

Hi,
I also got one. Feeltech FY2200S (10MHz)
but i have a problem with the offset voltage. See measurements below. Can someone please check if they have the same offset issue?

Set      Measured
0.0       0.001
0.1       0.209
0.2       0.314
-0.1      0.045   (positive?  must be negative)
-0.2      -0.059

By the way, the signals are made with 8 datalines from a FPGA (altera max II) these digital lines are fed to a R2R network..

There are some adjustment potmeters inside. found the ofset one and the anplitude one. but there is one more..

Thanks,
peter.

Thanks for the software. I received my FY2200SP today but the CDROM was infected by a virus.
Thanks
Paul

Isn't this the same signal generator as the other thread which I started in May?

Of course it's the 24MHz version in my thread, but should be within same series, not?
