:MEASure:TVOLt

Query Syntax

N O T E

(see page 530)

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

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

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

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.

The :MEASure:TVOLt command is obsolete and is provided for backward compatibility to previous oscilloscopes. Use the :MEASure:TVALue command (see page 244) instead.
