RD JDS6600 25MHz 2-Channel DDS AW Function Signal Generator
<< < (32/44) > >>
joeb8:
I can not find the trigger signal from the generator used for during a sweep generator function.
I have never heard of a generator that does the sweep function without the trigger / sync signal also being available to sync a scope.

thanx
takfuji:
Am frustrated, too. :(
My circumvention is to set the CH2 to exact same frequency and use it as the sync. I need to adjust the horizontal location on scope, though.

Scratch.HTF:
Does the waveform have a lot of jitter at particular frequencies (e.g. 3/7/17/27/37/47/57 MHz) which means that the sampling rate cannot be changed?

Hi Trys,
I second Hector's wish and also would like to see your schematic.
TinkeringSteve:
Btw, what's with the NOISE function of this device?
I connected it to an audio amp, and what comes out is nothing like white noise, it's some sort of buzzing sound, and you can actually set its frequency.
What is that good for? (maybe I am wrong to expect white noise here, but that pitched sound is not something I'd have in mind when someone says "noise")

EDIT:
I see, it's not an FPGA function or anything but also just a fixed table for DDS, and if I set it to 1 Hz, it does resemble noise with not very much high end. I guess it would be somewhat more useful if it had a lot more points in each table than those meager 2K.
