What you see in the above picture is a Trimble GPS satellite receiver. If you look at the LEDs on the front, it shows the Power and GPS Lock LEDs active. Thats normal operation indicating power is on and the unit is tracking and locked onto the satellite. In addition to the LEDs that are active, there are LEDs for Enabled (cell base station use), Active (cell base station use), Alarm (indicates something is wrong) and holdover (indicates that the satellite signal is not present, but the unit is still providing timing).
Your purchase is for a quantity of one Trimble GPS receiver. I have several used pulls from service, tested and working. Each was working correctly before being pulled (they had to work right up to the time they were shut off as they were in service). I further test each for satellite reception, lock and sync, 10 MHz output, proper holdover mode, I/O activity and the condition of the overall unit.
The picture below is the rear view of a Trimble receiver. Here you find the Antenna connection (N Female), the 10 MHz output (BNC Female), power connection and the I/O port.
I am using a HP unit shown below on the right for a 10 MHz output source and I am testing one of one my older service monitors. That is a Trimble unit on the left like you are looking at in the listing, a HP is the powered unit on the right. If you look close, you will see I also have a CT monitor in the circuit as well, I am using the signal from this particular HP for testing the CT compared to the Motorola. These two GPS receivers are being placed into use on my bench, the Trimble for my 10 MHz reference. I am testing using the Neg 54 VDC telco standard (actually my supply is -48 VDC).
Speaking of having fun and playing with these. Google these units, or go to the website below and discover the fun you can have:

Look at the Trimble information. Makes a dandy frequency reference for the test bench or accurate signal tracking for those weak signal applications.
Yours will be a working pull from service and retested. I don't sell junk, so I am going to test the one you get the same as I would test one of mine.
