Signal Generator and Logic Analyzer module for SainSmart DDS140 USB Oscilloscope

[pascal_sweden]

I have seen a review on this forum about the SainSmart DDS140 USB Oscilloscope.

But what about the optional Signal Generator and Logic Analyzer module that can be added through
the external feature connector?

Signal Generator module
==================

Are there any reviews available about the optional Signal Generator module?
If not, who owns such a Signal Generator module and can make a review?

I am interested in a review of the hardware and the software.

If the software is not that good, it could probably be improved later on.
But what about the hardware itself? Is that any good?

Logic Analyzer module
================

Are there any reviews available about the optional Logic Analyzer module?

Combination of Signal Generator and Logic Analyzer module
==========================================

Is it possible to mount BOTH the Signal Generator module and the Logic Analyzer module at the same time?
This seems not to be possible, as there is no passthrough feature connector on the module itself.

Combination of 2 Signal Generator modules
===============================

Is it possible to mount two Signal Generator modules at the same time?
This seems not to be possible, as there is no passthrough feature connector on the module itself.

Is it really only possible to have only one signal generator output in total?

SainSmart DDS140 USB Oscilloscope itself
==============================

Is the software really that bad?

But what about the hardware itself? Is that any good?

Using 2 SainSmart DDS140 USB Oscilloscopes on one and the same computer
=======================================================

Is it possible to use two of these USB scopes on the same computer, and link them together in the software, to have a 4 channel USB Oscilloscope?

Are the 4 input channels synchronized with each other? Did anyone try this scenario?

Some USB scopes offer this feature (e.g. SmartScope from Lab-Nation).

Nobody that has bought any of these optional modules?
