Notes about Sampling Using an External Clock Signal
• Roll mode display is not available in scope mode.
• There is no function for dividing the frequency of the clock signal.
• The time axis cannot be changed. To change the time-axis display range, change the record length, or
zoom in on the time axis.
• The measured time values in cursor measurements and automated measurements of waveform
parameters indicate the number of clock signal pulses. For these measurements, units are not displayed.
• The trigger settings listed below are invalid.
Trigger delay, period trigger, pulse width trigger
Maximum Sample Rates for Each Module
If you set the sample rate of the instrument to a rate that is higher than a module’s maximum sample rate,
because the data is updated at the module’s maximum sample rate, all the data within the module’s data
update interval will be the same. The maximum sample rates for each module are listed below.
