RD JDS6600 25MHz 2-Channel DDS AW Function Signal Generator

Yes! Finally! My JDS6600 has arrived!
Canada Post lost it for a couple of days, but after screaming at them loud enough to peel paint from a barn, I was able to convince them to bestir themselves, and lift a finger... and they discovered that they HAD mis-delivered it, and were able to retrieve it and get it into my hands. :phew:
Of course, this would be the weekend that my sister is moving, so my weekend is shot - and I'm tearing apart my hobby room in preparation for painting it, so that will add a few days onto the far end. So I won't have any decent time to play with my new toy for a while. Sigh.
Hey, RD Tech!. A little while ago, I posted

Yah, I must have been in a particularly bad mood when I typed that. It does look a little harsh, just standing there on its own, and I regret having typed that. So many products these days overstate their capabilities, especially the feeltech products. I should not have spoken harshly of your product before I even saw it. That was wrong of me, and I do apologize.
Speaking of the feeltech product, I came across a YouTube video in which a young engineer took it upon himself to improve on the old feeltech signal generator. With the addition of a few jumper wires and a couple of components, he improved it a great deal. The funny part was when he said," I don't know why they used XXXX part. This other part is a much better match for what they're doing, and it's cheaper!"
Have a good one, everybody - and Happy 150th Birthday, Canada! Yea!!!!!! :clap: :clap: :clap:

I also bought a signal generator, JDS6600 5mVPP effect is very poor, there is a clear switching power supply noise, more than 20MHz sine wave has a significant jitter, the nominal vertical resolution of 14, in fact, simply can not reach, Because the waveform length is only 2048 points, the highest resolution is only 11-bit resolution, the oscilloscope with 20mV voltage and 100nS time base gear test 5V 10Khz sine wave, you can see the rough rough waveform, and 14bit machine More than a lot of open the machine can see the DA is a simple resistor, which used a multiplier, or second-hand components, with a knife gently scraping the surface to drop the black powder.

Charlie,
I am familiar with a YouTube video to improve the MHS-5200 generator which had some serious output filter and output buffer issues. See:
http://www.analogzoo.com/2015/08/fixing-the-mhs-5200a/
However, I am not familiar with any such update for the Feeltech FY3200S generators. Can you provide a link for a Feeltech improvement video or did you confuse the MHS-5200 one as a Feeltech update?

Short review from a russian forum..
DDS generator JDS6600 (Google translate)
pantelei4:
The device has a very poor Electromagnetic compatibility,
Interference is caused by DC / DC motherboard converters.
This is noticeable immediately after switching on, if we put a probe next to it.
Sensitivity 500uV / div
Bandwidth 300MHz
The probes of the oscilloscope are connected to ground, there is no signal at the input, noise JDS6600 is very high.
