24 :MEASure Commands

:MEASure:SLEWrate

(see page 1610)

Command Syntax

:MEASure:SLEWrate [<source>[,<slope>]]

<source> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r>}

<n> ::= 1 to (# of analog channels) in NR1 format

<m> ::= 1 to (# math functions) in NR1 format

<r> ::= 1 to (# ref waveforms) in NR1 format

<slope> ::= {RISing | FALLing | EITHer}

The :MEASure:SLEWrate command installes a slew rate measurement on the

oscilloscope's front-panel screen.

The slew rate of an edge is the change in vertical value between the lower and

upper thresholds of a waveform source (typically volts) divided by the change in

time between where the waveform threshold crossings take place.

The lower and upper thresholds for the measurement are specified by the

measurement threshold settings for the source waveform (see :MEASure:DEFine).

If the <source> parameter is not specified, the current :MEASure:SOURce setting is

used

The on-screen edge closest to the timebase reference is measured.

You can specify that a RISing edge be measured, a FALLing edge be measured, or

either a rising or a falling edge be measured (EITHer). If the <slope> is not

specified, a rising edge is measured.

Query Syntax

:MEASure:SLEWrate? [<source>[,<slope>]]

The :MEASure:SLEWrate? query returns the measured slew rate of the specified

edge closest to the timebase reference.

Return Format

<value> ::= slew rate in vertical units/second in NR3 format
