Description
Specifies the scaling factor by which the probe you attach to the channel attenuates the input. If the oscilloscope is auto sensing the probe attenuation, setting this attribute to a positive value configures the oscilloscope to use the manual probe attenuation you specify. For example, for a 10:1 probe, you set this attribute to 10.0.
After this attribute is set to a positive value, you must set this attribute to reflect the probe attenuation each time the probe physically changes.
This class driver reserves negative values to control oscilloscopes with auto probe sense capability.
