content: I know it's old and not that high spec, but I think it's more than enough for me as the first scope, which I brought it about $50 incl shipping.And it come to me everythings seem fineThe system status said:Software Version: 3.01.01.21Hardware Version: 3-41-1.61Product Type: ADS1102CALSERIES: 01020100300734and I learn that the ATTEN ADS1102CNL is more or less the same to Sigilent SDS1102CNL, and it can be SDS1102CML if I solder a SRAM chip on it, it will has 2Mpts long memory function, nice!So the next thing I did was update it to newer SDS1102CNL firmware,From the below link, I learn that ADS1102CAL can use EasyScopeX or WaveStudio after flash the SDS1102CNL firmware...https://eevblog.com/forum/testgear/firmware-update-for-atten-ads1102cal-oscilloscope/Quotehere is another flash ADS1102CNL to SDS1102CNL and use EasyScopeX and WaveStudio without any problemQuoteI think I installed the NI-Visa driver properly, I can see a device in devices manager, and NI-Max can detect the scope and send command, but the only command it responses is "*IDN?". EasyScopeX list the scope at "add device", but it will prompt "fail to connect to the device".And I notice one things, after they flashed the SDS1102CNL firmware, they scope's product type changed to SDS1102CAL and mine is not.At first, it's no "type" at all, and the power on splash is totally white, then I flash a "Atten_CAL.cfg" download from the forum, both power on "ATTEN" splash and the product type in system status came back, ADS1102 still. So do I need to flash a "SDS1102CNL.cfg" in order to let EasyScopeX recognize my machine?

content: Thanks. I've view a lot of related thread and almost all of their problem is answer by you, so is mine!Problem sovled!I've ordered the missing SRAM chip to have it became SDS1102CML, so I guess I will need a SDS1102CML.cfg as well then?

content: I soldered the 2M sram IC to the PCB with quite some effort... but everything seem fine, I have my sds1102cml now. Thank you for everything, the patch firmware and all the kind replies.

content: I do a litte test of the save bit depth of the new 2M SRAM ic, then find out that with or without Long Memory mode, dual Channels saving points is full function, in another world, in any time div, the captured waveform length will equal: ( 2M or 40K ) = Sampling Rate * 2 * LengthWe know if only 1 channel is active, either the sampling rate is double, or the capture waveform lenght is double, but, that is not the case to my scope, in fact most of the time div setting, only half memory is used... I list the result in a excel sheet:Even an old Siglent promotion PPT show tell you if only 1 channel is used, it use all the 2Mpts saving, but my test show is not in time div 500us.So my question is:do I miss some tweaking to allow 1 channel use all memory in more time div? Or it's a limitation of ADS1102CAL --> SDS1152CML, or it's just false promotion PPT, the real SDS1152CML work exactly like my hacked ADS1102CAL?
