Oscilloscope ads1102cml
« on: April 16, 2013, 08:23:49 am »
I'd like to know if this type of memory IS61LPS51236A-200TQLI is used in atten 1102cml (siglent 1102) digital storage oscilloscope

the problem is that atten specify 1G sampling rate for a 8 bit vertical resolution
so 36bit / 8bit = aprox. 4
4 * 200MHz = 0.8GHz (maximum 800 megasamples)
what is wrong hire?
1.) not this type of memory IS61LPS51236A-200TQLI
2.) or not 1GS
Please help me!

With long memory, samplerate max is half. (500MSa/s)
(this is very normal in many cheap DSO:s)

Only short memory is full speed. (it is 40k or 20k + 20k)

EV of course. Cars with smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

Wises must compel the mad barbarians to stop their crimes against humanity. Where have the (strong)wises gone?
