TDR/TDT Commands (Rev. A.06.00 and Above)
RESPonse:VLOad?
This command specifies the vertical range of the TDR/TDT response and changes the vertical
tracking setting to MANual if it is in AUTO. Refer to “RESPonse:VERTical” on page 22-8. The
value <N> is an integer, 1 through 4, that identifies the response waveform. The
<range_value> argument is in the current UNITs setting and suffix supplied. (The suffix does
not set the UNITs; it is ignored.)
Restrictions Available in all software revisions. TDR mode.
Example 10 OUTPUT 707;":TDR:RESPONSE1:VERTICAL MANUAL"
20 OUTPUT 707;":TDR:RESPONSE1:VERTICAL:RANGE 5 V"
Query The information reterned from the query is only valid when the vertical tracking mode is set
to manual.
:TDR:RESPonse<N>:VERTical:RANGe?
Returned Format [:TDR:RESPonse<N>:VERTical:RANGe] <volts><NL>
RESPonse:VLOad?
Query :TDR:RESPonse<N>:VLOad?
Queries the V
load
value for calculating the impedance for TDR or TDT responses. Use
“RESPonse:VAMPlitude?” on page 22-7 to return the value of V
amplitude
. Use the equation listed
under “RESPonse:VAMPlitude?” on page 22-7 to calculate the impedance. A settings conflict
error is reported if no stimulus channel is active or if the query is sent for a TDT response. If
the response is uncalibrated, a default value is returned. The value <N> is an integer, 1
through 4, that identifies the response waveform.
Restrictions Software revision A.06.00 and above. TDR mode.
Example 10 OUTPUT 707;":TDR:RESPONSE1:VLOAD?"
Returned Format [:TDR:RESPonse<N>:VLOad] <value><NL>
STIMulus:EXTernal
Command :TDR:STIMulus:EXTernal {ON | 1 | OFF | 0 }
Specifies that an external pulse accelerator is being used in the test setup.
Restrictions Software revision A.06.00 and above. TDR mode.
Example 10 OUTPUT 707;":TDR:STIM:EXT ON"
Query :TDR:STIMulus:EXTernal?
Returned Format [:TDR:STIMulus:EXTernal] {ON | 1 | OFF | 0 }<NL>
STIMulus:EXTernal:POLarity
Command :TDR:STIMulus:EXTernal:POLarity {POSitive | NEGative}[, {POSitive | NEGative}]
When using an external step accelerator, sets the polarity of the channels to match the polar-
ity of the TDR remote head. For single-ended measurements, the first argument is required
and defines the polarity of the external step. For differential or common mode measure-
ments, both arguments are used with the second argument defining the second external step
polarity.
Restrictions Software revision A.06.00 and above. TDR mode.
