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)
If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.
It is much easier to think an apple fall to the ground than to think that the earth and the apple will begin to move toward each other and collide.
