RATC
pixel RATe Calibration factor
Class System parameter settings
Description Sets an internal multiplication factor used in setting the pixel clock frequency. The
multiplication factor can be set to compensate for the frequency error of the internal
reference crystal. Having to use a factor outside of the typical range may indicate a failure
of generator's hardware. Reinitializing the generator's memory sets the calibration factor
to a factory-default setting of 1.00000.
Note: The RATC parameter is a system level parameter that will affect the pixel clock
frequency of all formats that are recalled. The RATC value will be retained when the
generator is powered down and back up again. Query the current setting of RATC if you
are experiencing problems with the pixel clock or scan rate being off in frequency.
Command syntax RATC factor
