This dual interface module is used to connect the optical probe (Keysight 8162x) to the 8163A/B, 8164A/B or 8166A/B mainframe
The following optical probes should be used in conjunction with these interfaces.
81620B Silicon, +10 dBm to -90 dBm
81623B Germanium, +10 dBm to -80 dBm
81624B 5 mm InGaAs, +10 dBm to -90 dBm
81626B InGaAs, +27 dBm to - 70 dBm
