Description
Latlon designed and made the Rubidium Frequency Standard clock (made in USA), with 10M, 60M, 0~20M and 1pps out, internal clock uses Spectratime SRO-100 Rubidium standard (Swiss made, high accuracy option, typical: ±1E-11 / month); by gps disciplined, if use GPS, please connect the stable GPS more than 24 hours, less than 24 hours the offset value will NOT been stored to EEPROM, as usual, if the GPS connected more than 24 hours, the center frequency of 10MHz will very close to 10MHz, then you can plug out the GPS antenna, after 5 years, if the center frequency is left the 10MHz about 1E-9, you can plug the GPS antenna for more than 24 hours again to calibrate it;this one can act as frequency reference for your frequency testing; also it has the 0-20MHz output, can easily change or read the frequency by "iSyncMgr", check the attached picture, you can generate 16.9344MHz etc, also 44.1KHz, 48KHz word clock for the audio equipment, the accuracy is better than 100 times of the commercial audio word clock;
pls check the 100 seconds test result, the mean value and peak to peak tolerance;
the panel include 4 LED indication, power (normal green), track (blue), locked (sharp green), GPS 1pps (yellow), out is 4 ports (SMA), 10M, 60M, 0~20MHz, 1pps (Rubidium out, refer to GPS);
the 60MHz signal, via GRA & FACH AD9959 board, can reach 225MHz, please check the last picture (the AD9959 board and PA can find in ebay, just seach "AD9959 Shield");
the internal GNSS module is Ublox M8T, the most accurate for the world in commercial use;
the real panel include one RS-232 port, for Rubidium clock debug, you can see any info of the clock (use Hyper terminal or Lady Heather), one is TTL port, you can view or change the setting (by U-center or Lady Heather), select the GNSS system etc;
one SMA port is for GPS (3.3V) antenna; power supply is DC 12-16V, at least 2.5A, for the first 5 minutes, the current is 2.5A, than will be 1A or less than 1A, DC interface is 5.5*2.1mm
size is: 270*142*52 mm
weight: 1.23 Kg
the auction include:
one Rb standard (the house material is high quality aluminum);
two USB to serial cable (one is RS-232 for RB module, one is TTL for GPS module, both are FTDI chip);
one new Trimble or U-blox GPS antenna (SMA interface);
one new AC (110-240V) to 12V power adapter;
one user guide (soft copy, I will give you donwload link when you buy it);
one year warranty;
ship to US (all 50 states) by USPS or Fedex. other country please contact me if can ship and the will calculate the shipping cost (sensitive country do not contact me, this is high accuracy kit).
Please do not forget to give me feedback for the auction when you received it;
BTW, according the SRO-100 manual, the 10MHz output is Sine wave, but since no low pass filter circuit (the PCB can output 5MHz, 10MHz, 15MHz, default is 10MHz, so can not add LPF), the output Sine wave is not so pure, if you need the more beatiful, please add a 10MHz LPF in the output by yourself, check the picture (I tested it with a Mini-Circuits SLP-10.7).
