:MEASure:TVALue
Query Syntax
:MEASure:TVALue? <value>, [<slope>]<occurrence>[,<source>]
<value> ::= the vertical value that the waveform must cross.
The
value can be volts or a math function value such as dB,
Vs, or V/s.
<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<m> | MATH<m> | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
When the :MEASure:TVALue? query is sent, the displayed signal is searched for
the specified value level and transition. The time interval between the trigger event
and this defined occurrence is returned as the response to the query.
The specified value can be negative or positive. To specify a negative value, 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
value level in the positive direction. Once this value 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 r9.9E+37. This
value is returned if the waveform does not cross the specified value, or if the
waveform does not cross the specified value 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><NL>
NOTE
This query is not available if the source is FFT (Fast Fourier Transform).
