TDR/TDT Commands (Rev. A.05.00 and Below)
RESPonse:VERTical:RANGe
Query The information reterned from the query is only valid when the vertical tracking mode is set
to manual.
:TDR{2 | 4}:RESPonse<N>:VERTical:OFFSet?
Returned Format [:TDR{2 | 4}:RESPonse<N>:VERTical:OFFSet] <volts><NL>
RESPonse:VERTical:RANGe
Command :TDR{2 | 4}:RESPonse<N>:VERTical:RANGe <range_value>
This command specifies the vertical range of the TDR/TDT response when the vertical track-
ing mode is set to MANual. <N> is an integer, 1 through 4. This value refers to the stimulus
channel used to produce a response waveform, while the response waveforms are numbered
based on the destination channel. For TDR commands, the response waveform numbers and
RESPonse<N> refer to the same waveforms. This is not the case for TDT related commands.
<range_value> is in the current UNITs setting and suffix supplied. (The suffix does not set
the UNITs; it is ignored.)

STIMulus
Command :TDR{2 | 4}:STIMulus {OFF | ON | ON1 | ON2 | ON1AND2 | ON3 | ON4 | ON3AND4| COMMonmode | DIFFerential
| ECOMmon | EDIFferential | EXTernal}
This command turns the TDR/TDT stimulus on or off. This command is set before starting
normalization to specify type of normalization or reference plane calibration to perform. For
the differential stimulus setting, a reference plane calibration is executed unless you specify
which normalization procedure is to be executed using the :TDR {2 | 4}:DCALib command.
• The stimulus may be OFF, ON, or EXTernal.
• In slots 1 and 2, the stimulus may be OFF, ON1, ON2, ON1AND2, DIFFerential, COMMon-
mode, EDIFferential, or ECOMmon.
• In slots 3 and 4, the stimulus may be OFF, ON3, ON4, ON3AND4, DIFFerential, COMMon-
mode, EDIFferential, or ECOMmon.
After specifying the TDR/TDT stimulus, use the command :TDR<N>:PRESET. This command
will set up the instrument for TDR or TDT measurements based on the selected stimulus.
The argument, OFF, turns off the pulse generator, using the channel as a regular analyzer
channel. ON, ON1, ON3, and External turn on the channel 1 or channel 3 pulse generator for
single-ended TDR or TDT measurements. ON2 and ON4 turn on the channel 2 or channel 4
pulse generator for single-ended TDR or TDT measurements. ON1AND2 and ON3AND4 turn
on the pulse generator for channels 1 and 2 or channels 3 and 4 for simultaneous single-
