1.7.7 10 MHz Output
Signal: 10 MHz sine wave
Signal Level: +13 dBm ±2dB into 50
Harmonics: ˗40 dBc minimum
Spurious: ˗70 dBc minimum TCXO
Connector: BNC female
Signature Control: This configurable feature removes the output signal whenever a major
alarm condition or loss of time synchronization condition is present. The output will be
restored once the fault condition is corrected.

Note: Oscillator accuracies are stated as fractional frequency (i.e. the relative fre-
quency departure of a frequency source), and as such are dimensionless.
