10 MHz GPSDO-PLL

Main functions

• PLL-GPSDO 10 MHz
• New version 2021 with very low phase noise
• 10 MHz sine wave output
• 1 PPM output
• GPS NMEA RS232 output

Parameters

• Supply voltage: DC 11.7 - 13.8 V / <= 5 W
• GPS antenna voltage: DC 5 V/0.1 A
• Output 1PPS signal: square wave, 3.3 Vpp, synchronized to UTC
• 10 MHz output: sine wave
• 10 MHz output power: 11 dBm +/- 2 dB
• RS232 output: signal GPS NMEA, 9600 bps
• Accuracy: peak value 0.03 Hz at 10 MHz
• Average frequency stability: 0.0001 Hz at 10 M
• Dimensions: 138 x 25 x 68 mm (W x H x L including connectors)
• DC plug included

⚠ This is a PLL style GPSDO - lock time can be up to 10 to 60 min.

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

• SMA-BNC cable (total length about 50 cm)
