days at 85°C which would be equivalent to 125ppb over 2.25 years at
40°C.
Allan Deviation, Clipped Sine Wave Output
Test Conditions are under room ambient air fl ow (non insulated
conditions).
The VT-803 start up time is rated at 2ms. Figure 1 shows the Output
Frequency versus time in seconds which shows the output reaching a
steady state frequency within 60 seconds.
