EEVblog 1624 - Electronex: Liquid Instruments Moku Oscilloscope

[EEVblog]

An interview at the Liquid Instruments stand at Electronex 2024 about the Moku range of multi-function mixed signal oscilloscope, designed and built in Australia!
Thanks to Ben Price for answering the questions even though he's the mechnical engineer!

Hello,

I am a little disappointed by the specs of the analog inputs.

Moku:Pro:
Bandwidth (-3 dB)  300 MHz / 600 MHz switchable
Sampling rate  5 GSa/s with 1 channel, and 1.25 GSa/s with 4 channels
Resolution  10 bits
Noise: 300 / 400 uV RMS at 400 mVpp (if my guess is reasonably correct)
Memory: Deep memory captures > 60 million samples (Logic Analyser has  262k × 16 input sample depth and up to 32,764 x 16 output sample depth)

Specs are on par with the standalone oscilloscopes in this range.
The Pro version is a bit expensive, but packs a lot of features. It's an Australian company, so you can't expect chinese prices. And they seem to be doing a great job.

Actually the product is more on par with the Analog Discovery. Unfortunately the specifications are severely lacking details. Things like input ranges/sensitivities (if these are even adjustable?) are missing. The 'datasheets' are what I would call a short form brochure. A datasheet should enable people to make a technical purchase decission but this is not possible with what is provided for the Moku devices.

I am suitably impressed with the available instrument suite.
Sure, its bandwidth is a little on the shy side.
The GUI appears to be extremely intuitive, a must for an instrument with so many capabilities.

And nowadays, where it appears that every instrumentation breakthrough announcement comes from a Chinese company, it is refreshing to see someone else coming up with smartly designed devices.

The Go doesn't have a full spec sheet yet, but you can see in the datasheet its rated +/-25V:

If you look at the Lab there is a full spec sheet:

https://download.liquidinstruments.com/documentation/datasheet/hardware/mokulab/Datasheet-MokuLab.pdf

Analog in ranges: +/-1V or +/-10V.

So the Go is probably one 25V range.

As mentioned in the comments/video, these are designed for laser research labs, where it sounds like you just need low voltage inputs.

Yeah, niche market, not a general purpose scope.

Good.
