    General Information

    The SPC-QC-008 TCSPC module has eight absolute photon timing channels. Alternatively, the module can be operated with seven parallel TCSPC channels and a common reference channel on a single PCI-express board. The module features high temporal and spatial resolution, extremely high peak count rate (up to 500 MHz), and extraordinarily high timing stability. The SPC-QC-008 offers the usual modes for recording temporal waveforms of optical signals, sequential recording multi-wavelength recording, time- and parameter-tag recording.
