What are the differences between the Evaluation PCB Versions?

 

AR Version and PEPCB-EVAL-MCX-RES-P

Compatible with PEVAL-KIT-MCX (Optical Bench)

PE33xx-WB-AR Front
AR version
PEPCB-EVAL-MCX-RES-P
PEPCB-EVAL-MCX-RES-P
MCX Connectors Bias, Signal Out
Readout DC, resistive tap matched to 50 Ω (load resistor of 51 Ω on the board)
Typical Applications General purpose, suitable for all applications which only need a single voltage signal output
Recommended for All applications
Pulse Shape Example Pulse shapes of the Signal Output (without preamplifier) when illuminating with a short laser pulse < 1 ns. Please note that due to the DC coupling there is no undershoot of the signal visible. Example shows PE3325-WB-AR with the standard load resistor of 51 Ω on the board. Signal Output of PE3325-WB-AR was directly connected to an oscilloscope with 50 Ω termination.

AX Version and PEPCB-EVAL-MCX-P

Compatible with PEVAL-KIT-MCX (Optical Bench)

PE33xx-WB-AX Front
AX version
PEPCB-EVAL-MCX-RES-Pin
PEPCB-EVAL-MCX-P
MCX Connectors Bias, Signal Out, Monitor Out – all signal lines are matched to 50 Ω
Readout AC, impedance matched to the preamplifier
Signal Out 90% of the unamplified signal
Monitor Out 10% of the unamplified signal
Typical Applications Simultaneous Timing (Amplified Signal) and Energy Measurements (Monitor) (e.g. Spectroscopy, PET); Using full dynamic range of SiPM: Amplified Signal for Single Photons, Monitor output for higher light intensities (which drive the preamplifier into saturation)
Recommended for Timing critical applications; Applications which need simultaneously two outputs; Applications with a DC offset on the signal
Pulse Shape Example Pulse shapes of the Signal Output (without preamplifier) and the Monitor Output (without preamplifier) when illuminating with a short laser pulse < 1 ns. Please note that due to the AC coupling there is an undershoot of the signal visible. Example shows PE3325-WB-AX. Both Signal Output and Monitor Output of PE3325-WB-AX were directly connected to an oscilloscope with 50 Ω termination.
