Either the tool is just too good to find fault, or just not fitting the bill at all.
I would really appreciate if some one points out some short fall of the equipment so that we can make necessary changes to the hardware or software.
By the way we have released a new version (Ver 2.1) of the software which enables data analysis (viewing the profile) and measurements at the same time. This came in as a feedback from the user where he is continuously measuring current profiles after changes to the firmware and does not want to wait till the capture is completed. The new release also reduces the CPU loading to about 25% on a Core i3 @2.3GHz. The RAM usage is reduced to 512MB and below at all times. So the tool can run on almost all Windows machines.
Next-up we would release a viewer only program which can run without the tool for the data to be analyzed on any computer.
Many are suspicious about the tool achieving high dynamic range from few uA to 1A and accuracy of 1%+/-1uA across the range with just a 0.1 Ohm burden resistor. This is possible only with some precision analog components and some wacky hardware design along with signal processing on the GUI.
The hardware does not perform any signal processing, and this makes the equipment noise very low. The tool just streams raw samples to the PC using a FT2232H IC. The GUI does the all the DSP operations and data compression. The compression achieved is almost 100x. For e.g. a 24hour recording is possible on a 10GB file and this makes it possible to record long profiles.
I was working as an application engineer for Texas Instruments for 17 years and was experimenting with a lot of precision circuits over there.
