hi, tv84, I just got this old ads1102cal on a flea market, and I got almost the same system status of "bithead9" got, so I decide to update the oscilloscope.
I download the latest firmware of siglent 1102cnl firmware, which is V6.01.01.21R2, with the name "P21R2.ADS", but the machine refuse to flash the firmware, saying "product type is not accordant"
I wonder where I can download this old "SDS1000CNL_SSP_V100R005B01D02P13.ADS" to give a try... or I just missed some manoeuver to bypass the product type chek?
***EDIT*****
I think the V6.01 is not for CNL, those V5.0 work fine, but the some fireware didn't come with the CFG file and instruction, wandered around a bit before I learn that.
