:MEASure Commands
Introduction to
:MEASure
Commands
The commands in the MEASure subsystem are used to make parametric
measurements on displayed waveforms.
Measurement Setup
To make a measurement, the portion of the waveform required for that
measurement must be displayed on the oscilloscope screen.
Measurement Error
n/a :MEASure:VTIMe?
<vtime>[,<source>]
(see page 374 )
<vtime> ::= displayed time from
trigger in seconds in NR3 format
<source> ::= {CHANnel<n> |
FUNCtion | MATH | WMEMory<r>} for
DSO models
<source> ::= {CHANnel<n> |
DIGital<d> | FUNCtion | MATH |
WMEMory<r>} for MSO models
<n> ::= 1 to (# analog channels)
in NR1 format
<r> ::= 1-2 in NR1 format
<d> ::= 0 to (# digital channels
- 1) in NR1 format
<return_value> ::= voltage at the
specified time in NR3 format
:MEASure:VTOP

page 375 )
:MEASure:VTOP?
[<source>] (see
page 375 )
<source> ::= {CHANnel<n> |
FUNCtion | MATH | WMEMory<r>}
<n> ::= 1 to (# analog channels)
in NR1 format
<r> ::= 1-2 in NR1 format
<return_value> ::= voltage at the
top of the waveform in NR3 format
