TRIGGER:MAIN:PULSE:SLEWRATE:SLEWRATE?
returns the slew rate. It is given as an appropriate amount of volts per second.
For example, 

1.2E+6 would represent a slew rate of 1.2 megavolts/second.

Sets the upper and lower slew rate trigger thresholds. This is equivalent to
selecting Thresholds from the main Trigger’s Slew Rate menu and entering a
value in the resulting side menu’s High Threshold or Low Threshold items.
