The module connector types vary depending on the operating band and
impedance of the purchased unit:
• The IF Input/Output and LP (Loop) In/Out connectors are typically BNC
female connectors.
• The RF Input/Output and LP (Loop) In/Out connectors may be Type 'N' or
Type 'SMA' female connectors, depending on the application.
• All modules feature a 'J3 | HSB' (High Speed Bus) connector. Table 4-6
provides the pinout specifications for this D-Sub 25-pin female (DB-25F)
connector. The mating connector is a DB-25M connector.
