Commands by Subsystem 3

:MEASure:OVERshoot

(see page 530)

Command Syntax :MEASure:OVERshoot [<source>]

<source> ::= {CHANnel<n> FUNCtion MATH}

<n> ::= {1 2 3 4} for the four channel oscilloscope models <n> ::= {1 2} for the two channel oscilloscope models

The :MEASure:OVERshoot command installs a screen measurement and starts an overshoot measurement. If the optional source parameter is specified, the current source is modified.

N O T E This command is not available if the source is FFT (Fast Fourier Transform).

Query Syntax :MEASure:OVERshoot? [<source>]

The :MEASure:OVERshoot? query measures and returns the overshoot of the edge closest to the trigger reference, displayed on the screen. The method used to determine overshoot is to make three different vertical value measurements: Vtop, Vbase, and either Vmax or Vmin, depending on whether the edge is rising or falling.

For a rising edge:

overshoot = ((Vmax- Vtop) / (Vtop- Vbase)) x 100

For a falling edge:

overshoot = ((Vbase- Vmin) / (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 after the chosen edge, halfway to the next edge. This more restricted definition is used instead of the normal one, because it is conceivable that a signal may have more preshoot than overshoot, and the normal extremum would then be dominated by the preshoot of the following edge.

Return Format <overshoot><NL>

<overshoot>::= the percent of the overshoot of the selected waveform in NR3 format
