Tested/Guaranteed • Latest PTP Firmware • TCXO Oscillator • Option 34 - Dual NTP/PTP Servers • Large Red LED Display • Correct Date and DST Observance • 110-240V AC Power • Atomic Clock Time Receiver

Multiple item listing - there will be some very small, non-performance affecting cosmetic
variations between units.  The photos are representative of the condition of all units.

Introduction

Here's a lightly used GPS disciplined master clock unit with an Option 34 (NTP/PTP) add-in board installed. This provides two Ethernet ports both capable of running NTP and PTP timekeeping protocols. It also has IRIG-B, Serial and 1 PPS outputs as well as an impressive and hard-to-find optional large red LED time display. The unit has been tested to confirm that it works as it should. The unit comes with a basic antenna to allow you to test the unit immediately upon receipt. For a permanent installation an outdoor antenna with a full view of the sky will be required. The antenna voltage is 5V so almost any professional GPS antenna with a gain of 26dB or more will suffice. The PTP board firmware has been upgraded to the latest version available at the time of listing. Ethernet Port 2 is set to DHCP address assignment so you can easily access the web config screen (see screenshots below). The web login is set to the default value - clockoption:password.  The GPS receiver is a late model 12 channel type that shows the correct date - see photos.

Description

Focused on high performance and maximum value, the Model 1084C delivers high end time-keeping results.

Three BNC connectors deliver several output options supporting IRIG-B modulated, and various combinations of IRIG-B unmodulated, Programmable Pulse (supporting multiple output modes) and 1 PPS. All are high drive outputs capable of driving multiple loads wired in parallel.
