Measure Commands
TDR:AVERage
Example This example returns the time interval between the trigger event and the 90% threshold on
the second rising edge of the source waveform to the numeric variable, Time.
10 OUTPUT 707;":SYSTEM:HEADER OFF" !Response headers off
20 OUTPUT 707;":MEASURE:TEDGE? UPPER,+2"
30 ENTER 707;Time
NOTE When receiving numeric data into numeric variables, turn off the headers. Otherwise, the headers may cause
misinterpretation of returned data.
TDR:AVERage
Command :MEASure:AVERage {CHANnel<N> | RESPonse<N>}
Measures the average TDR impedance for the selected channel or response.
Restrictions TDR mode. Software revision A.05.00 and above (86100C instruments).
Query :MEASure:AVERage? {CHANnel<N> | RESPonse<N>}
The query returns the calculated average voltage of the specified source.
Returned Format [:MEASure:AVERage] <value> [,<result_state>]<NL>
The <value> argument is the calculated average TDR impedance. 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:AVERAGE? RESP1”
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>}
