The HP 83447A lightwave trigger receiver is used to generate an electrical trigger signal from an optical waveform. A typical usage is for eye-diagram analysis of telecommunications optical signals where an external electrical clock signal is not available as a timing reference. Data rate (NRZ) 50 Mb/s to 2.5 Gb/s Operating input power Minimum 20 dBm Maximum +3 dBm Maximum through-path optical insertion loss 1.5 dB Minimum electrical trigger output return loss 10 dB Minimum electrical output level Optical input > -15 dBm 400 mV pk-pk Optical input > -20 dBm Characteristics Maximum output jitter 2 measurement. <1000 Mb/s at -15 dBm 0.012 UI (rms) <1000 Mb/s at -20 dBm 0.02 UI (rms) >1000 Mb/s at -15 dBm 0.03 UI (rms) >1000 Mb/s at -20 dBm 0.05 UI (rms) Wavelength range 1200{1600 nm Maximum safe, continuous optical input power 10 mW peak Nominal trigger output impedance 50 ohms
