Description
Run SPC whenever the external reference is more than 0.1% (1000 ppm) different than the
nominal reference or the reference at which SPC was last run.
The timebase changes in correspondence to the fluctuations in the external reference.
≥ 4 GHz models: 10 MHz
< 4 GHz models: 10 MHz
≥ 4 GHz models: ≥ 200 mV
< 4 GHz models: ≥ 1.5 V

≥ 4 GHz models: 1.5 kΩ, C
< 4 GHz models: 385 Ω, C
≥ 4 GHz models: Low (stable) jitter mode: ± 100 ppm
High (tracking) jitter mode: ± 1%
Running SPC is required whenever the external reference is more than 0.1% (1000 ppm)
different from the nominal reference frequency or reference at which SPC was last run.
< 4 GHz models: 9.8 MHz to 10.2 MHz
≥ 4 GHz models: 10 MHz
