But after reading the excellent 8 part review of SDS1104X-E written by Performa01 I am a bit disappointed by how little this software provides and I am not even sure that I will get the WifFi adapter. --- Quote from: Performa01 on January 27, 2018, 10:11:59 am --- https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/ --- End quote --- What a great review! Believe you or not but you answered 99% of all my questions. I was wondering about Lissajous figures, differential voltage measurement on this DSO, difference between different types of 50 om terminators, how SDS1202X-E handles square waves and a lot of other information. I was searching for the info about SDS 1202X-E and I am pretty much sure many other people did that too - I found very little and did not find Performa01's review in particular. But it never occurred to me than when you say "sds1104" you mean more than just one model. I am pretty much sure that every potential buyer of SDS 1XXX device would greatly benefit from reading the documents in question. |

The WiFi just adds convenience and portability over hard wired LAN and the same functionality of the inbuilt webserver is available in/with either remote connection type. When I was beta testing a SDS1104X-E I used a laptop and WiFi that I actually found a lot more convenient to be away from my normal work space and the email and online distractions like EEVblog. Using direct WiFi connection was a little more troublesome than through a WiFi access point as there's no DCHP to help with simple connection and each time you closed connection (shutdowns) you'd have to reassign IP's rather than save them and just turn ON the WiFi and be back where you finished. It was a bit of a PITA to do it that way, but entirely possible if needed/required. |

Still have not heard back from my seller regarding SDS1204X-E and I am slowly getting impatient. I see that right now SDS2204X is on sale -1.5K USD + some extra. It gets really attractive. I am curious - the manual says "max. sampl. rate 2GSa/s". How many ADC does SDS2204X have and what the actual sampling rate if all 4 channels are in use? Will it be 2GSa/s per channel or what? |
| Performa01:
For the SDS2204X It’s exactly the same as with the SDS1000X(-E), just twice the sample rate. So for the four channel models you get two ADCs and in case of the SDS2kX this provides 2 x 140Mpts @ 2GSa/s or 4 x 70Mpts @ 1Gsa/s. Average and Eres as well as X/Y are generally limited to 7/14kpts though. |

This issue appears to be dealt with in the latest SDS10004X-E firmware: https://www.eevblog.com/forum/testgear/siglent-sds1204x-e-released-for-domestic-markets-in-china/msg1420112/#msg1420112 7.Fixed a bug in the I2C triggering system of 7 bit Address& Data There's been a firmware release for SDS1202X-E too but it's not listed in the changelog for the 2ch version. :-// Maybe someone can check.... http://siglenteu.com/gjjrj-xq.aspx?id=4072&tid=15 |
