TDR/TDT Commands (Rev. A.05.00 and Below)
RESPonse
This command sets the period of the TDR pulse generator. You should usually leave this set to
AUTO unless you need to define a specific rate. In AUTO, the instrument will attempt to keep
subsequent periods off screen when the timebase is changed. <rate> is the period to which
you want to set the generator, in Hertz. You can add a suffix to indicate that the rate is in
Hertz (HZ, KHZ, and so on).
Restrictions Software revision A.05.00 and below. TDR mode.
Example 10 OUTPUT 707;":TDR2:RATE 120 KHZ"
Query :TDR{2 | 4}:RATE?
The query returns the current period of the pulse generator, even when the control is set to
AUTO. The query is allowed in all modes.
Returned Format [:TDR{2 | 4}:RATE] {AUTO | <rate>}<NL>
Example 10 OUTPUT 707;":TDR2:RATE?"
RESPonse
Command :TDR{2 | 4}:RESPonse<N> {ON | 1 | OFF | 0 | DIFFerential | COMMonmode | INDividual}
This command turns on or off a TDR or TDT normalized response. <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 wave-
forms. This is not the case for TDT related commands. OFF turns off the response for the
specified stimulus. ON turns on the normalized response of the channel.
The keyword NORMalize may also be used. This command is compatible with the
Agilent 83480/54750 and is equivalent to ON.
The DIFFerential argument turns on the differential response. COMMonmode turns on the
common mode response. INDividual turns on the response for the corresponding channel.
This option is valid for responses computed by the differential normalization procedure, as
set by commands :TDR {2 | 4}:DCALib:NORMal or :TDR {2 | 4}:DCALib:QNORmal.
Restrictions Software revision A.05.00 and below. TDR mode.
Example The following example turns on common mode response on response 1.
10 OUTPUT 707;":TDR2:RESPONSE1 COMMONMODE"
Query :TDR{2 | 4}:RESPonse<N>?
The query returns the current response setting for the specified stimulus. The query is
allowed in all modes.
Returned Format [:TDR{2 | 4}:RESPonse<N>] {OFF | DIFFerential | COMMonmode | INDividual | ON}<NL>
RESPonse:CALibrate
Command :TDR{2 | 4}:RESPonse<N>:CALibrate
This command begins a TDR or TDT normalization and reference plane calibration. Which
calibration is done (TDR or TDT) depends on the setting of the TDRTDT control. <N> is an
integer, 1 through 4. This value refers to the stimulus channel used to produce a response
