Valid Operating Modes
The NihonKohdenSource only accepts specific sampling rates. The number of channels acquire is limited at sampling rates of 5000 Hz and above. The following table shows all valid combinations of sample rate and maximum number of channels.
| Sample Rate | Valid Sample Block Sizes |
|---|---|
| 100 Samples per second | 256 Channels |
| 200 Samples per second | 256 Channels |
| 500 Samples per second | 256 Channels |
| 1000 Samples per second | 256 Channels |
| 2000 Samples per second | 256 Channels |
| 5000 Samples per second | 128 Channels |
| 10000 Samples per second | 64 Channels |
