Measure Commands
TMAX
Returns the minimum impedance (Y-axis ) value that is to the right side of the reference
plane.
Returned Format [:MEASure:TDR:MIN {CHANnel<N> | RESPonse<N>}] <value><NL>
Example 10 OUTPUT 707;”:MEASure:TDR:MIN RESPONSE1”
TMAX
Command :MEASure:TMAX [<source>]
Measures the first time at which the first maximum voltage of the source waveform occurred.
The source is specified with the MEASure:SOURce command or with the optional parameter
following the TMAX command. In TDR mode, the time reported is measured with respect to
the reference plane. <source> is {CHANnel<N> | FUNCtion<N> | WMEMory<N> |
RESPonse<N>}. <N> is an integer, from 1 through 4.
Mode Oscilloscope and TDR modes.
Query :MEASure:TMAX? [<source>]
The query returns the time at which the first maximum voltage occurred.
Returned Format [:MEASure:TMAX] <time>[,<result_state>]<NL>
<time> is the time at which the first maximum voltage occurred. If SENDvalid is ON, the
<result_state> is returned with the measurement result. Refer to Table 18-3 on page 18-30
for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:TMAX?”
NOTE When receiving numeric data into numeric variables, turn off the headers. Otherwise, the headers may cause
misinterpretation of returned data.
TMIN
Command :MEASure:TMIN [<source>]
Measures the first time at which the first minimum voltage of the source waveform occurred.
The source is specified with the MEASure:SOURce command or with the optional parameter
following the TMIN command. In TDR mode, the time reported is measured with respect to
the reference plane. <source> is {CHANnel<N> | FUNCtion<N> | WMEMory<N> |
RESPonse<N>}. <N> is an integer, from 1 through 4.
Mode Oscilloscope and TDR modes.
Query :MEASure:TMIN? [<source>]
The query returns the time at which the first minimum voltage occurred.
Returned Format [:MEASure:TMIN] <time>[,<result_state>]<NL>
<time> is the time at which the first minimum voltage occurred. If SENDvalid is ON, the
<result_state> is returned with the measurement result. Refer to Table 18-3 on page 18-30
for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:TMIN?”
