The DPO7OE Series Optical probes can be used as Optical Reference Receivers (ORR) for high speed serial data signals (using selectable Bessel-Thomson ORR filters), or can be used as a conventional O/E converter for general wide-bandwidth optical signal acquisition. The DPO7OE Series is compatible with DPO/MSO70000 C/DX/SX models. Connect to TekConnect channels for up to 33GHz electrical bandwidth. Connected to ATI channels, the DPO7OE1 provides up to 42GHz electrical response; the DPO7OE2 provides up to 59GHz electrical bandwidth response.
