DSO QUAD is forming, make a WISH?
Seeed Studio and Bure (aka Chai Xiaoguang, the designer of DSO Nano) never stopped improving our oscilloscopes. Now we can introduce you the new model, DSO QUAD.
Comparing to portable easy DSO Nano, QUAD is an intermediate version with more powerful performance and functionality. Target features as below:
- A first prototype has been made earlier, defining basic structure and functionalities like below
- 2 Analog channel, 20mV to 10V/div, h36Msps sampling rate, approximate 30Mhz bandwidth, AC/DC coupling.
- 2 Digital channel, ext. trigger source. Simple AD measurement of 0-5V, DC coupling.
- 1 Analog signal generator output 10hz~20kHz customizable waveform via DAC.
- 1 Digital signal generator output 10hz~8MHz square wave.
- Interface for Bee series/FILM and Electronic Brick Sensors.
- Internal 2Mb USB storage
- Designed for hacking, over-clocking, re-purposing, mutants
- Open source platform with APP store (building)
- Still compact, wearable(or not), rugged,
This is still an early review of the product, mass production still need at least 2-3 months, target price >150$, trimmed version might be available too. More project info and community comments will be collected on our WISH platform, please feel free to vote, comment or publish your ideas! Participation will be converted to credits on Seeed Depot.

I’ve read the comment of Teo.I’ve bought the DSO Quad beta and I’m waithing the delivery. I’m very worried about this problem. There is the possibility to find a solution also in the Beta version?
Thanks

Teo’s comment does sound pretty urgent, more so if the units are in assembly right now.
What if Seeed were to test the application some kind of an adhesive around the connectors that could be done by the customers to see if this solves the problem?
The testers would have to include the adhesive and instructions so that anyone could do this.
Or, better yet, can you guys (Seeed) use a bracket that has through hole, load bearing, footers (on each corner) that can be twisted on the opposite side of the pcb to secure the mount? It would be a simple stamped bracket made from thin steel OR perhaps plastic……….. just drill the holes on the pcb, insert the bracket, and twist the footers (or if plastic I guess they’d snap in place) and assemble the unit back together!!!!!!!!
Guys, please pay attention to the signal connectors. They are mechanically anchored ONLY through the copper layer on PCB. I worked with them – they snap off by just looking at them. If I’m correct and they are only held by copper layer then this will compromise this wonderful concept that’s otherwise very nicely done; you’ll get lots of complaints and frustration.
Would like to have a kaskadeable serial digital connection, for external FPGA and A/D + D/A konverters, that would allow improvement modules, or communication with own electronics (open protocol). The idea is, that you could use your DSO scope, for expansion modules, that could support more inputs, higher resolution, or much higher samle frequence, and kaskade your modules to have more inputs or outputs. Each module, contain a small FPGA that could be programmed with the time for the sample, and the FPGA has memory enough to contain the sample, and transfer it using the serial protokol “slow” to the DSO nano. The digital protocol should be open, so you could build your own modules, or use it for your own electronics, that includes an A/D or D/A konverter. The digital connection, may have a common “trig-line”, that works as wired-or, and allows same trig signal, to be feeded to this line, and use the same input signal for the trig. Each FPGA, could be programmed to feed the trig line, by the protocol, and thereby select the input to use for trigger.
The idea with an open digital connection standard, is to allow infinite expansion, with both signal generators, scopes, and maybe logic analyzers, that each only consist of an FPGA, a D/A og A/D converter, and the needed amplifier electronics, as PGA’s (programmable gain amplifiers). The protocol defines how to read or send a sample, to set the time of sample, to define input trig, and set amplification and input type (AC or DC). It also could be able to automatic find the number of equipments attached, and the features (e.g. speed, number of samples, of bit resoultion, of features as AC/DC, and PGA input range and amplification values). It might also support FPGA’s used for digital propes, and any number of programmable digital output waveforms.
If the scope has a feature to see a lot of analog and digital signals, and if the name or number of the channel could be read by the serial connection, then I guess I would use the protocol for my own electronics, so I could use a DSO nano/quad scope, to debug the signals inside the electronics.
– Larger serial-flash chip than 2MB, I would pay extra for 8MB. Even more important is microSD or microSDHC slot, but it doesn’t look like you have room for it.
– Low PPM oscillator for more accuracy.
– SSMA or SSMC input connector.
A little bit Softawre for Brain Wave Monitoring
or Heart Wave Monitoring would be great.
With a extra Port to conecting the electrode.

10v is just way too low to be useful and a very backward step. Maybe add an isolation amplifier such that much higher voltages can be safely probed. (maybe with a wireless or fibre connection)
The phono connectors are cheap but really, really nasty.
@nate, @total_nerd
10V/Div means that it probably does go up to 30 or so volts. Not that it can’t measure more than 10V.
