The memory depth corresponds to the displayed time window (time base x 10 grid sec-
tions in horizontal direction) multiplied by the current sampling rate. The minimum
value is determined by the maximum sampling rate and the maximum signal repeat
rate of the oscilloscope. The displayed sampling rate corresponds to the current sam-
pling rate divided by the amount of data skipped while reading out from the acquisition
memory. If peak detection is activated, the displayed sampling rate corresponds to the
current sampling rate.

MAX. SA. RATE
The instrument sets the maximum sampling rate while using the maximum memory
available. Thus, it displays the maximum amount of data. Each column in the signal
window displays up to 40 detected data values (limited by processor performance).
How much data is displayed depends on the displayed time window and the current
sampling rate. If peak detection is activated, each column displays up to 20 pairs of
min/max values. The memory depth always corresponds to the maximum acquisition
memory. The displayed sampling rate is identical with the current sampling rate. Peak
detection is used if the displayed time window contains more data than 40 * signal win-
dow columns in the acquisition memory or min/max data in the acquisition memory.
If the maximum sampling rate is selected, the entire oscilloscope memory can only be
read out in "STOP" mode.
