:FUNCtionN:THReshold:RFALl:TOP?
Description
For the indicated function, sets or queries the Rise/Fall threshold's custom top-level setting. The top and base levels are used to locate a waveform's lower and upper threshold levels for the rise time, fall time, and slew rate measurements. Specify the level in volts or Watts depending on the waveform type. Use :FUNCtion:THReshold:RFALl:BASE to set or query a custom base level.
Before this user-defined top level can be applied to measurements, use the :FUNCtion:TBASe:RFALl:METHod command to select user-defined top-base definitions.
