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.
TRIGger:MAIn:PULse:SLEwrate:THReshold:BOTh
TDS 684A & 7XXA Only
Sets the upper and lower slew rate trigger thresholds. This is equivalent to 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.

TTL
TTL sets the upper threshold to 1.8 V and the lower threshold to 0.8 V.
ECL sets the upper threshold to –1.1 V and the lower threshold to –1.5 V.
TRIGGER:MAIN:PULSE:SLEwrate:THRESHOLD:BOTH TTL
sets the trigger runt threshold to TTL.
TRIGger:MAIn:PULse:SLEwrate:THReshold:HIGH
TDS 684A & 7XXA Only
Sets or queries the upper (most positive) limit of the two threshold levels that a
pulse edge must traverse for the slew rate trigger to occur. This command is
equivalent to setting the higher threshold in the Pulse Slew Rate Trigger’s
Thresholds side menu item.
