--- Quote from: nctnico on April 28, 2017, 05:37:17 pm ---Another Micsig TO1104 (tBook mini) review Samplerate, memory and timebase The maximum samplerate is 1Gs/s but it is divided over the channels. With 2 channels enabled the samplerate drops to 500Ms/s and with 3 or 4 channels enabled it drops the samplerate to 250Ms/s. The same goes for the memory. There is 28Mpts of memory but with 3 or 4 channels enabled the maximum memory length is 7Mpts. One thing which is annoying is that when pressing the auto setup it also switches the memory length to automatic instead of the user selected setting. I prefer to stay in control of the memory depth. User interface Unfortunately the buttons outside the display area seem unresponsive at some times and take several presses before they react. I guess this is a sensitivity problem for the capacitive sensing circuit Micsig used. Comparison If you look at the price and specs then the TO1104 is at the lower end of the spectrum where the GW Instek GDS-1000B series, Keysight DSOX1000 series, Rigol DS1054Z and Siglent SDS1000X / SDS1202X-E are located. Each of these scopes have their advantages and disadvantages. The Rigol DS1054Z has 4 channels but it is slow to operate, the Keysight DSOX1000 and Siglent SDS1000X / SDS1202X-E only have 2 channels and while the GW Instek GDS-1000B series has 4 channels and the deepest memory of all (with all channels enabled) it has no decoding. It really depends on what you find important to make a choice. One thing is clear: in this price range you have to compromise. --- End quote --- Thanks nctnico for the excellent review. I have a couple of questions: 1. About the maximum sampling rate. In case I use only 2 channels of a 4-channel version of the scope, will the sampling rate for each channel be 500Ms/s or 250Ms/s? Is this the same with the GDS-2204E and the DSOX1102G (500Ms/s per channel since there are only two channels)? 2. Any improvement with the touch sensitivity since your posting? Perhaps a firmware upgrade would improve the situation? 3. I cannot find GW Instek GDS-2204E mentioned in your comparison with various other scopes. How is it compared with the Micsig tBook mini TO1104? Basically, I am trying to decide between the GDS-2204E, one of Micsig's tBook or tBook mini, Keysight's new DSOX1102G and the Rigol 1054Z. 4. Is it possible to hack the Micsig's scopes to get more bandwidth like the Rigol's 1054Z? 5. I suppose one cannot get the 2-channel version first and buy an upgrade kit to upgrade it to the 4-channel version. Am I right? |

I ended contacting the sales team and buying direct, the price I paid is more than the offer prices heres (there as a 70MHz to 100MHz free upgrade offer at the time).

In think of the choices you list the GDS2204E is the most complete scope feature wise but if you have a little extra money to spend it might be a good idea to look at GW Insteks MSO2204AE which is a GDS2204E with 2 function generators and 16 digital channels. In the $500 area you always have to compromise. If you can spend somewhere around $1500 you can end up with a general purpose oscilloscope which does everything well (deep memory, responsive UI, lots of nifty features and firmware which works). AFAIK you can't hack the MicSig scopes and you can't add 4 channels later. The maximum samplerate for the MicSig mini-tbook (TO1000 series) is 250Ms/s with 4 channels enabled. The GW INstek GDS2000E and MSO2000 have 500Ms/s as maximum samplerate with 4 channels enabled. |

I guess one good thing about the MicSig scopes is that they have a touch screen. If I were rich, I would have bought the Keysight DSOX3024T or 3034T. Somewhere in between there is a TO202A with 200MHz 2 channels (2GSa/s, 90Mpts, 500,000 wfms/s) if I can do with only two channels. Honestly speaking, I don't know what specs I need and different manufacturers have different definitions. It is hard for me to make the comparison. In one of my threads, I recall somebody mentioning that for my applications (university level in electrical/mechanical/mechatronic engineering, seeing outputs from motor drivers, arduino mega or above), I would need about 150MHz. |

--- Quote from: Cliff Matthews on December 16, 2016, 05:19:29 pm ---Mikeselectricstuff has a great 65-minute teardown here: He covers everything but the aux jack output (this looks like a product needing more software refinement). --- End quote --- The video mentioned a few issues: 1. Lack of fine adjustment in both vertical and horizontal time scales. 2. Random reboot. 3. Can't do pinch zoom (in the mini models only?) 4. Even an AC adapter is used, the battery needs to be in the device for it to work. 5. autoscale function is hidden rather than listed explicitly on the right of the screen. 6. lack of serial decode I would imagine that since all the buttons are virtual buttons, it would be easier to move things around and improve the GUI than traditional scopes. It has been half a year since the video was made. Have these issues been fixed? Do they happen only to the TO1104 or other scopes made from Micsig? |
