The A-PPI-D from Becker & Hickl is a passive device used to transform positive pulsed signals such as TTL output pulses of detectors or trigger sources into signal pulses suitable for accurate detection with Becker & Hickl TCSPC modules.
Optional 10dB or 20 dB in-line attenuators are also available (A-SMA-10dB and A-SMA-20dB). You can select the A-PPI-D plus attenuator in the pull down product selector above.

| Pulse Inversion | |
| For Trigger signals from pulsed lasers and fast APDs | |
| Principle | leading or falling edge of incoming trigger pulse is differentiated |
| Response to short pulses (< 2 ns) | one inverted pulse (only first edge of input pulse is differentiated) |
| Response to longer pulses (> 2 ns ) | bipolar pulse, first peak is inverted to input pulse (differential of first and second edge of input pulse) |
