NTCAP scaler assignment |
|
|
The setup contains two NI-6612 I/O cards with BNC-2121 connector accessories that provide eight inputs each for TTL scaler signals.
Important: When connecting scaler signals make sure that they are TTL (not NIM)!
Additionally, there is the possibility to assign data streams (eg clocks) from other modules in the NI chassis to scaler channels.
Below you find the assignment of the channels on the software side, including the internal clocks. This is important when analysing the .tmds files.
|
Channel | Input | Comment
| |
0 | 10 MHz clock | external (from NI 6674T timing module)
| |
1 | DC trafo | ion current in ESR
| |
2 | injection trigger | from Genesys (IO2 on sddsc221)
| |
3 | U-cooler | cooler voltage
| |
4 | I-cooler | cooler electron current
| |
5 | P-gun | pressure at e-cooler
| |
6 | 100 kHz clock | internal
| |
7 | 20 MHz clock | internal
| |
8 | software trigger | from Detectomer
