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

(1/44) > >>

CharlieWorton:
I was going to buy a cheap Feeltech, but some have reported that its lack of proper grounding is allowing voltages of around 90 volts at 1 milliamp to run through the probes.  Concerns have been raised about connecting it to mpus and such.  So I was kind of resigned to swapping out the internal power supply for something better, which is expensive and bothersome.

Then I came across this thing - an 'RD JDS6600 Series 25MHZ Digital Control, Dual-channel, DDS Function Signal Generator/frequency meter Arbitrary sine Waveform' thingie.

Here's a link to AliExpress:
https://www.aliexpress.com/item/RD-JDS6600-Series-25MHZ-Digital-Control-Dual-channel-DDS-Function-Signal-Generator-frequency-meter-Arbitrary-sine/32811781657.html?spm=2114.12010108.1000023.4.2xZidl

Let's see what I remember.  A full color LCD display on the front.  Power through a wall wart, so no high voltage transients running around.  Some very nice software that appears to do a lot more than the remote control software for the Feeltech.  A whack of pre-programmed waveforms, most of which have names I don't recognize.  A proper sine wave up to 25Mhz.  And apparently some decent square and triangle waves up to 15Mhz (the feeltech crapped out around 4Mhz).  The ability to store up to 60 different user defined waveforms, as well as sample an incoming wave form.  Dual channel outputs.

There are a ton of specifications on the site.  I won't pretend to know whether they're significant.  I'm hoping you folks do.

They want $140 Canadian including e-packet shipping (which is pretty fast).  The Feeltech was $85, plus whatever I have to do to solve the voltage transient problem.

I have the impression that this thing is somewhere in between the Feeltech cheapie, and a name brand signal generator from Rigol et al.

I'm leaning towards buying one.  I'd sure appreciate feedback from all of you.  Or any of you.

Let me know what you think, Kay?  Thanks, folks - Charlie

CharlieWorton:
Here's kind of a youtube video about the signal generator:

There's no audio - not even a muzak track - but you get a closeup of the face of the unit being manipulated by what I suspect are Chinese hands.

Sure seems to do a lot.

Well, I guess we'll all find out together!   ;D

I've ordered it from AliExpress, and they'll be shipping via e-packet.  So I should have it in about 3 weeks.

When it shows up, I'll share my experiences here.

Take care, all.  Hope this works!

Nice to hear! I look forward to your review and take it apart video :)

Perhaps you could link him to some of your teardown or review videos to help him better understand what you are asking for.
