Hi Edgardo, they work well for me, look brand-new, and came with power supply, rs-232 cable, and antenna. I think it's a 5V antenna. The unit had about 37000 on the lifetime. The seller has close up photos, that's what the units look like. I plugged in the power, ran GPSCon to start an Auto-Survey, and they just worked. I now get less than 3us predicted drift over 24 hours from one of the units, which is quite good according to others. I think these are pretty good for the money (free shipping on mine) but there are differences between the three units I have just like the Z3801A plots on leapsecond.com. Hope that helps, Said In a message dated 9/7/2012 17:13:22 Pacific Daylight Time, xe1...@amsat.org writes:
Dear Said, Good afternoon. How is the service and cosmetic condition of the HP GPS products you have bought from this source? I am considering a Z3805A just for the sake of owning one and the versatility of plug and play. Still afraid to take the plunge. Did you buy a raw unit? Or as a kit with antenna. Is that a 5V or 12V antenna? I am integrating a TBolt into a 1U rack case which also has space for a Rb oscillator for future disciplining. Got a nice TBolt monitor and would love to also include a frequency divider to get 5 and 1MHz from the TBolt. Your kind comments are welcome. Thank you.
