SPECIFICATIONS

No need of other equipment and input reference signals, processing standard frequency compare (test) by GPS timing signal.
The compare signal inputted can be signals of crystal oscillator, Rb Frequency standard or Cs standard, and 1PPS signals.
Good ability in continuous running, no requirements for people on duty.
Automatic in saving frequency compare magnitude (result), running continuous and calculating frequency excursion rate.
Timing (time) and frequency comparing available
Connect directly with computer through RS-232C interface, and output frequency compare magnitude (result).

Clock face display (hour, minute, second)
When processing frequency compare, collect and process data automatically and show the magnitude result (relative frequency difference) directly. Save the result automatically.
Output GPS standard second (1PPS), and TTL electrical level
RS-232C standard serial interface (output time information and frequency compare magnitude)
Timing precision: ±1μs (GPS，1PPS，RMS，SA OFF)
Frequency compare precision: ×10—9/100S、 1×10—10/1000S
