Calibrating the master oscillator
4.2 Calibrating the master oscillator
Calibration of the Master Oscillator is achieved by means of a PPS (Pulse Per second) signal generated by
e.g. a (D)GNSS position sensor like the TT-6588A (D)GNSS Receiver.
1. The equipment ambient temperature shall be within 20° to 30° Celcius.
2. The TU must be powered up and left idle for 30 minutes prior to calibration.
3. Connect the PPS (Pulse Per second) signal from the (D)GNSS Receiver to the TU AUX-connector pins
7 (+) and 8 (-) as indicated in the AUX termination table for Cable 10, page 2-21.
To access the TU AUX connector use cable p/n S-406209-941. Should the cable need be extended
the TT-6209A Connection Box may be used as shown in below drawing.
If the TT-6288A (D)GNSS receiver is used for sourcing the PPS signal, connect a 10k pull up resistor
between the (D)GNSS Receiver positive supply input (+) and J21 Out terminal.
