What is the maximum digital input trigger rate?
The maximum digital input trigger rate in a system including Master 400 or higher is 20 kHz.
When using a standalone sensor or a sensor connected to a Master 100, the maximum trigger rate is 32 kHz. This rate is limited by the fall time of the signal, which depends on the Vin and duty cycles. To achieve the maximum trigger rate, the Vin and duty cycles must be adjusted as follows:
|Maximum Speed||Vin||Maximum Duty Cycle|
|32 kHz||3.3 V||88%|
|32 kHz||5 V||56%|
|32 kHz||7 V||44%|
|32 kHz||10 V||34%|
At 50% duty cycle, the maximum trigger rates are as follows:
|3.3 V||34 kHz|
|5 V||34 kHz|
|10 V||22 kHz|
