Front panel

BNC output: 10 MHz sine wave
BNC 1PPS: pulses 1PPS, synchronized to UTC
PWR LED indicator: indication of supply and GPS lock - blinking (GPS not locked), long light (GPS locked), no light (missing power supply)
ALM LED indicator: light (accuracy better than 0.1 Hz), no light (accuracy lower or the same as 0.1 Hz)

Rear panel

SMA female for GPS antenna with 5 V
Jack 3.5mm RS232 GPS NMEA 9k6
DC jack

Warm up start

The first start in new location can take around 10 minutes
Depends on satellite count and GPS antenna position
There is also warm up of the internal TCXO box - also a few minutes
