The LED-PG pulse generator module is designed to supply the optimal pulse current, pulse width and pulse repetition frequency (prf) for the LMS LED's. There is a trade-off between these parameters: for example, too high a pulse current or prf will cause overheating and damage to the LED, while longer pulses allow lower band-width detectors and simpler signal detection circuitry to be used.
The LED-PG pulse generator is normally supplied with the following factory setting:
These setting are safe for all LMS LED's operating without a heatsink at room temperature. Pulse settings can be changed by rotating one of three multi-turn potentiometer screws labelled 'pulse width', 'repetition rate', and 'current'. The setting ranges are listed under specifications.
