MEASUrement:MEAS<x>:DELay:DIREction
Description
This command sets or queries the starting point and direction that deter-
mines the delay "to" edge when taking a delay measurement. Use the
MEASUrement:MEAS<x>:SOURCE2 command to specify the wave-
form. This command is equivalent to selecting Time from the Measure

Syntax 2
MEASUrement:MEAS<x>:DELay:DIREction?
Arguments
H BACKWards
This means that the search starts at the end of the waveform and looks
for the last rising or falling edge in the waveform. Use the MEASUre-
ment:MEAS<x>:DELay:EDGE2 command to specify the slope of the
edge.
H FORWards
This means that the search starts at the beginning of the waveform and
looks for the first rising or falling edge in the waveform. Use the
MEASUrement:MEAS<x>:DELay:EDGE2 command to specify the
slope of the edge.
Example 1
MEASUrement:MEAS3:DELay:DIREction BACKWards
This command starts searching from the end of the waveform record.
Example 2
MEASUrement:MEAS3DELay:DIREction?
This query might return
:MEASUREMENT:MEAS3:DELAY:DIRECTION BACKWARDS
indicating that the current search direction is backwards.
