3 channel DDS generator purchase

[KlausKragelund]

Hi

I have a Siglent 2 channel DDS generator, but sometimes I need 3 channels

I have been searching and sofar no hits

Anyone recommend one? (I would like better quality than Aliexpress :-))

Thanks

Klaus

Yup, almost impossible to find:

Why not getting another one? Do you need 3 channels on the same device?

Actually in Aliexpress using the search term "3 channel signal generator" came up empty. Adding a dash now suddenly showed the product you linked to ("3-channel signal generator"

Thanks for the help

I need to be able to apply 3 phase with 120 degrees between them. Does the Siglent SW support linking them together like that?

I have done exactly this with a Tektronix AWG430.

There is also Wavetek 195, which is 4 channel. It's a little older and has 12 bit resolution, but with a lot of features. It's the same model as Aim/TTi TGA1244 for which one can find documentation.

The Siglent DDS units have an external trigger input which can be used to start the output.

For instance, see page 56 (physical page 67) of:

SDG1000 models have been replaced with SDG1000X, a far better instrument.
These have a Sync output especially for ganging together multiple units.

once you have the two phases with 120 degrees between them the last one is just an add and invert

Yes, but do you have a box like that just handy?

Come to think of it, why doesn't anyone sell a box that has amplifiers etc, seems like there could be a marked for it, except for the cheap not sure it works Aliexpress stuff

obviously depends on frequency and load, but in the simplest case an opamp and three resistor would do

This is an idea for a new product (power amplifier) I have for a while but so far no time to actually build it.
