:MEASure:TVOLt

(see page 1276)

Query Syntax

:MEASure:TVOLt? <value>, [<slope>]<occurrence>[,<source>]

<value> ::= the voltage level that the waveform must cross.

<slope> ::= direction of the waveform. A rising slope is indicated by

a plus sign (+). A falling edge is indicated by a minus

sign (-).

<occurrence> ::= the transition to be reported. If the occurrence

number is one, the first crossing is reported. If

the number is two, the second crossing is reported,

etc.

<source> ::= {<digital channels> | CHANnel<n> | FUNCtion | MATH}

<digital channels> ::= {DIGital<d>} for the MSO models

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

<d> ::= 0 to (# digital channels - 1) in NR1 format

When the :MEASure:TVOLt? query is sent, the displayed signal is searched for the

specified voltage level and transition. The time interval between the trigger event

and this defined occurrence is returned as the response to the query.

The specified voltage can be negative or positive. To specify a negative voltage,

use a minus sign (-). The sign of the slope selects a rising (+) or falling (-) edge. If

no sign is specified for the slope, it is assumed to be the rising edge.

The magnitude of the occurrence defines the occurrence to be reported. For

example, +3 returns the time for the third time the waveform crosses the specified

voltage level in the positive direction. Once this voltage crossing is found, the

oscilloscope reports the time at that crossing in seconds, with the trigger point

(time zero) as the reference.

If the specified crossing cannot be found, the oscilloscope reports +9.9E+37. This

value is returned if the waveform does not cross the specified voltage, or if the

waveform does not cross the specified voltage for the specified number of times in

the direction specified.

If the optional source parameter is specified, the current source is modified.

Return Format

<value> ::= time in seconds of the specified voltage crossing

in NR3 format

NOTE

The :MEASure:TVOLt command is obsolete and is provided for backward compatibility to

previous oscilloscopes. Use the :MEASure:TVALue command (see page 509).
