Introduction

Here's a lightly used GPS disciplined master clock unit with IRIG-B, Serial and 1 PPS outputs as well as an impressive and hard-to-find optional large red LED time display. The oscillator is a TCXO type. The LCD display does not have the optional backlight installed. 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 will suffice. Note that the red LED digits in the display have some difference in illumination levels - see photos. This doesn't affect the functionality or legibility of the clock. The unit has Option 28 installed - to measure AC line frequency via the System Reference BNC connector at the rear. I don't have the special cable that connects to this jack so I have not tested that function. The option does show up in the front panel config menus.

Important... This item includes an updated GPS card to replace the now-obsolete model originally installed by the factory. There's a reason why you can find a lot of Arbiter GPS clocks being sold cheaply. That's because nearly all have failed GPS receiver cards that are reporting the wrong date (ie. nearly 20 years in the past). Sadly most other sellers somehow neglect to mention this in their enthusiasm to sell you a failed device. For the buyer, there's nothing more disappointing than finding after you've gone to all the trouble of rigging up your outdoor GPS antenna that the "precision" clock you just bought can't even show the right date. So before you buy a clock elsewhere, ask the seller for a photo of their clock showing the correct date and time.

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.
