1.6.3 10 MHz Output
Signal: 10 MHz sine wave
Signal Level: +13 dBm ±2dB into 50 Ω
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 out-
put will be restored once the fault condition is corrected.
Accuracy rating depends on the oscillator selected during the ordering process.

Note: Oscillator accuracies are stated as fractional frequency (i.e. the rel-
ative frequency departure of a frequency source), and as such are dimen-
sionless.
