1. 9-16V DC power input: Use the included 12V supply, or a battery that can source 40 watts.
2. 50Ω type N RF Input: Do not exceed +20 dBm or damage may occur.
3. SMA GPS antenna port: The GPS antenna (included) may be connected here to discipline
the time base and time stamp I/Q data
4. Trigger In: The rising or falling edge of a digital 3.3V or 5V signal may be used to trigger
in I/Q streaming modes.
5. 10 MHz out: Use to synchronize external equipment requiring a 10 MHz input
6. 10 MHz in: Disciplines internal timebase to an external 10 MHz source. 0 to +15 dBm
recommended.
7. USB 2 connector: Only used for firmware upgrades.
8. SFP+ connector: 10 GbE bi-directional data connection to the PC, using an optical SFP+
module and fiber optic cable.
9. GPIO port (DB15): Can be used to control external equipment, such as an external
antenna switch. Commands may be embedded within a sweep. See GPIO Port for more
information.
10. Status LED: Alternates red/green as commands are processed and sweeps are
generated.
