How can I access to the maximum memory depth (32M/16M) as stated in the U2701A/U2702A Modular Oscilloscope's data sheet?
You can see the effects of maximum memory depth 32/16 Mpts in the zoom mode of the AMM software that comes together with the unit. The memory depth enables you to further zoom in the time scale when you select a smaller timebase value. However, when you try to save the wave form with a CSV file, it will only allow you to save a maximum of 1250 data points.
