19 :MEASure Commands
:MEASure:PREShoot
(see page 860)
Command Syntax
:MEASure:PREShoot [<source>]
<source> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<r> ::= 1-2 in NR1 format
The :MEASure:PREShoot command installs a screen measurement and
starts a preshoot measurement. If the optional source parameter is
specified, the current source is modified.
Query Syntax
:MEASure:PREShoot? [<source>]
The :MEASure:PREShoot? query measures and returns the preshoot of the
edge closest to the trigger, displayed on the screen. The method used to
determine preshoot is to make three different vertical value measurements:
Vtop, Vbase, and either Vmin or Vmax, depending on whether the edge is
rising or falling.
For a rising edge:
preshoot = ((Vmin-Vbase) / (Vtop-Vbase)) x 100
For a falling edge:
preshoot = ((Vmax-Vtop) / (Vtop- Vbase)) x 100
Vtop and Vbase are taken from the normal histogram of all waveform
vertical values. The extremum of Vmax or Vmin is taken from the
waveform interval right before the chosen edge, halfway back to the
previous edge. This more restricted definition is used instead of the
normal one, because it is likely that a signal may have more overshoot
than preshoot, and the normal extremum would then be dominated by the
overshoot of the preceding edge.
Return Format
<value><NL>
<value> ::= the percent of preshoot of the selected waveform
in NR3 format
