10 MHz
You must select either the internal reference (default) or 10 MHz external.
9.9 MHz to 10.1 MHz
You must run SPC whenever the external reference is more than 0.2% (2000 ppm) different than
the nominal reference frequency or reference at which SPC was last run. The time base changes in
correspondence to the fluctuations in the external reference.
for input frequencies between 9.9 MHz and 10.1 MHz
