Tmeas
= -20 °C (Class 2 beacon)
= beacon turn-ON time after 2 hours “cold soak”
= start time of frequency stability measurement (TON + 15 min)
Note: #2
The 2h and 1h warm-up and stabilisation times are for type approval test of complete beacon.
For testing of TCXO these times may be shortened accordingly.
