:MEASure:TVALue?
<value>
numeric
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>
string
+ -
direction of the waveform. A rising slope is indicated by a plus sign (+). A falling edge is indicated by a minus sign (-).
<occurrence>
integer
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>
string
CHANnel<n> FUNCtion MATH WMEMory<r>
the source of the waveform to be measured. <n> is the channel number (1 to the number of analog channels) in NR1 format. <r> is the waveform memory number (1-2) in NR1 format.
Searches the displayed signal for the specified value level and transition, and returns the time interval between the trigger event and this defined occurrence.
<value><NL>
<value> ::= time in seconds of the specified value crossing in NR3 format
Query the time when the waveform first crosses 1 volt in the positive direction.
:MEASure:TVALue? 1, +1
Query the time when the waveform second crosses -500 mV in the negative direction on channel 2.
