Measure Commands
TDR:MAX
TDR:MAX
Command :MEASure:TDR:MAX {CHANnel<N> | RESPonse<N>}
Measures the maximum TDR impedance for the selected channel or response. When used as
a query, the returned value uses the same units as the setting for the selected channel or
response. For example, if the channel units are set to volts, this query returns a value in volts.
Restrictions TDR mode. Software revision A.05.00 and above (86100C instruments).
Query :MEASure:TDR:MAX? {CHANnel<N> | RESPonse<N>}
Returns the maximum impedance (Y-axis ) value that is to the right side of the reference
plane.
Returned Format [:MEASure:TDR:MAX {CHANnel<N> | RESPonse<N>}] <value><NL>
Example 10 OUTPUT 707;”:MEASure:TDR:MAX RESPONSE1”
TDR:MIN
Command :MEASure:TDR:MIN {CHANnel<N> | RESPonse<N>}
Measures the minimum TDR impedance for the selected channel or response. When used as a
query, the returned value uses the same units as the setting for the selected channel or
response. For example, if the channel units are set to volts, this query returns a value in volts.
Restrictions TDR mode. Software revision A.05.00 and above (86100C instruments).
Query :MEASure:TDR:MIN? {CHANnel<N> | RESPonse<N>}
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 18-4 on page 18-39
for a list of the result states. When receiving numeric data into numeric variables, turn off the
headers. Otherwise, the headers may cause misinterpretation of returned data.
