3 Terms and Definitions
GB/T 4833.1 and GB/T 4960.6 regulations and the following terms and definitions apply to this section.
3.1
When the multi-channel analyzer as a multi-channel scaler, 1,2,4,8 entire memory can be divided into two partitions, each according to Shun Road
Work order. Memory partition selection should give way to divide memory partitioning, each partition available channel number and the selected partition number.
3.2
And promote the MCS channel stepping clock pulses corresponding to the period of time interval, namely to stay in the count every time.
3.3
Because MCS per channel memory write address step conversion and lost track of time. Net count every time is the residence time
3.4 Added to the MCS "count" logic pulse input
With any logic pulses fed to the MCS, as shall be specified at the input pulse
Said features.
a) polarity;
b) logic level;
c) width;
d) rise time and fall time;
