Description
SS
Sync Mode
Instructs the instrument to adjust the exposure time, when using Adaptive Sensitivity
mode, to the nearest even multiple of the refresh rate (frequency) of the source. Choices
are
No Sync, Auto Sync, and User Frequency.
In Auto Sync mode, the instrument measures the frequency of the source to determine its
period. The exposure time is then automatically altered so that it is an even multiple of
the source period (1/frequency).
User Frequency will adjust the exposure time based on a user enter frequency in Hertz as
entered using the SK command. See the User Sync Frequency section for more details on
defining the Sync frequency.
