IKALOGIC WS200 and SQ200

In today’s mailbag I received a box containing an IKALOGIC WS200 hand held scope and an SQ200 logic analyser.

SQ200 and WS200 unitsThese French-made units are oscilloscope and logic analyser respectively and they arrived in attractive packaging, directly from IKALOGIC in Limoges, France. Translations to English are spot-on, if only some others used the same care.

The packaging as it turns out was not only attractive but functional as the box arrived without any of the usual marks or dents.

To use these units it is necessary to visit  the IKALOGIC web site to grab the software which  is available for Windows/Mac/Linux/Android/IOS

First off, the WS200. I can honestly say, given my current recovery status, I was worried in case setup proved difficult, but my fears proved unfounded. These small units are easily set up (at least on a PC).

tmp90A7 The scope software installed without issue which allowed me to have an initial play by connecting the supplied micro-USB/USB lead.

As the WIFI connection is used for data, USB for power, you initially need the Ikascope to use its own internal access point and set your device to work with this access point, however once that is done you can tell Ikascope from that point on to use your normal access point if you wish (as I do).

I could however find no way to tell it about my WIFI access point. I contacted support by email and sure enough they pointed me in the right direction. The unit initially sets up its own access point and then can be used by putting your mobile device onto that network and once you have done that initially, it can in future be joined to your existing network.


So now, I turn on my Ikascope by merely pressing the probe (ProbeClick) and it immediately connects to my access point.

There’s not much to the above picture simply because there isn’t much to see externally on  the scope. No buttons to press, merely the probe to press (ProbeClick) to initiate a reading on your PC or mobile device on the downloadable “Ikascope” software. Simple. I like it.

The scope comes with the ground lead for the probe head and a USB lead for charging, along with a little setup card.


I’ve tested the unit on both my Windows laptop and Android smartphone. PC software shown above.

Here’s the Android phone screenshot.


Coming up next – a first look at SQ200..

The unit turns on automatically when connected to USB and the PC software has a clean interface. Of course, the software is also available for MAC and Linux, though not, it would seem, mobile Android/IOS devices.


The SQ200 unit has 4 inputs and handles a range of input voltages and supports a good range of protocols out of the box with more online.

Here we see the SQ200 unit running Scanastudio (3.0.14) on my laptop… testing I2c from a BME280 to an ESP8266 on Aidan’s new weather station.



Mustool G600 Microscope from Banggood

Some time ago, Banggood send me a Mustool G600 Microscope. The intended use for this was and is as a visual aid when assembling and testing small electronic boards (that’s what I need it for anyway).

MUSTOOL Microscope from BanggoodThe scope is excellent for this as it is adjustable from just a few mm height above the test object to 130mm or more. Resolution is also adjustable.

The unit has it’s own backlight and display and runs off USB. It also has an internal rechargeable battery and can run for many hours without a connection to USB power.

As it turns out, when the unit  arrived, I was stuck in hospital for some weeks and for some of that time had difficulty reading anything, full stop. The scope proved to be indispensible in helping me to read. It is worth noting that the scope has an SD memory slot and can make (quality) recordings but I’ve no use for that particular feature.

Now, my eyesight is more or less back to normal and I’m starting to look toward commencing board construction and testing again and the Mustool microscope now has earned a spot on my workbench.

Here is the Banggood link for the G600.

In the photo above, the scope is helping me assemble an Arduino-like board.

More of my Postbag

It could take some time before I’m fully fought up with my various postbags, here is some more:

Yokogawa TY720 True RMS Digital Multimeter

In the last entry I looked at the UNI-T UT61E Digital Multimeter in this entry I’ll talk about the Yokogawa TY720 True RMS Digital Multimeter.

Yokogawa  TY720

The TY720 is a solid unit and could well become my favourite meter. As well as the usual voltage, current and resistance measurements, this rather large, backlit, 5-digit beauty (which has closed-case calibration) has data memory and does diode testing, capacitance,  frequency measurement and more. Measurements can be absolute or relative and you can select min, max, average with auto-hold, data hold and more.

Frequency measurement is from 2Hz to 100Khz and temperature readings  from –200c to 1372c (with optional probe for temperature. I did not receive one of these).

The meter runs on 4 AA cells. Too early at this point to say how long they will last but it is easy to replace the batteries. Construction looks fine and overall appearance is good. At this point I can’t find anything negative to say. Operating temperature at –20c to +55c is outside of anything my unit will encounter.

All in all, a very nice meter.

I also have a very nice Owon meter with Bluetooth but as that is currently in storage, a review will have to wait a little while, meanwhile there is far, far more in the current batch of post that I still need to cover.
