The SIS 3820 is a latching scaler that can also provide timestamp
information. In regular use, it is a 32 channel 32 bit scaler
module. If used as a timestamper it provides 2 48 bit channels.
See the -timestamp for more information
about this.
-base integerSets the module's base address. The base addresses are set via jumpers or rotary switches, depending on the module hardware revision. The default value is 0.
-timestamp enable |disable When enabled, the module is run in timestamp mode. In timestamp mode, the module used as two 48 bit channels that increment when inputs 1 and 16 are pulsed. Normally in timestamp mode, the scaler is also externally latched on the event trigger e.g. The default is disable. In that case, the module is run as 32 channels of 32 bit wide scalers. This is normally used to display counters in the scaler display.
-inputmode selectionPrograms how the four NIM inputs are used. Any of the following values can be used for the selection:
Lets the software select an appropriate default mode
depending on the value of the -timestamp.
See default mode below. This is the
default value for this option.
All of the inputs are disabled.
Note that LNE means "Load Next Event" and means latch. Input 1 is the load next event signal (latch), Input 4, inhibits the LNE input.
Input 1 loads the next event, Input 3, inhibits scalers from counting and Input 4 inhibits the LNE input.
Input 1 is the latch (LNE) and input 4 inhibits the scalers from counting when asserted.
Each input inhibits four channels of the scaler. E.g. input 1 inhibits, channels 1-4, input 2 inhibits channels 5-8 and so on. Using this in timestamp mode issues a warning as there is no input that can latch the timestamp.
Not supported in
Input 1 is the LNE, input 2 inhibits counting and input 3 clears all of the scaler counters.
When default is selected, the input mode
depends on the state of the -timestamp.
If -timestamp is enabled, default is like selecting
LNEInhLNE. If -timestamp
is disabled, default is like selecting Inh4s.
-outputmode selection
Selects the meaning of the NIM outputs. The default value
is clock50Mhz. Valid values for
-outputmode are:
Output 5 duplicates the LNE while Output 7 is a 50MHz square wave clock.
Output 5 echoes the LNE. Output 8 is the user output which is not used by NSCLDAQ.
Output 5 echoes the LNE and outputs 6 and7 are 10MHz clocks.
Output 5 is the LNE and output 6 is a 10MHz clock.
