| Connector | Use |
|---|---|
| REF IN | Input terminal for an external reference signal for the local oscillator (LO) on the device. REF IN is a female SMA connector with an impedance of 50 Ω, and it is a single-ended reference input. REF IN accepts a 10 MHz signal with a minimum input power of 0 dBm (0.632 Vpk-pk) and a maximum input power of 15 dBm (3.56 Vpk-pk) for a square wave or sine wave. |
| USB | Input that accepts a standard USB cable. A suitable USB cable is included in the hardware kit. |
| PPS IN | Input terminal for pulse per second (PPS) timing reference. PPS IN is a female SMA connector with an impedance of 50 Ω, and it is a single-ended input channel. PPS IN accepts 0 V to 3.3 V TTL and 0 V to 5 V TTL signals. |
| PWR | Input that accepts a 6 V, 3 A external DC power connector. |
