TDR/TDT Commands (Rev. A.06.00 and Above)
RESPonse:RPLane?
RESPonse:RPLane?
Query :TDR:RESPonse<N>:RPLane?
Queries the reference plane position for TDR or TDT responses. The reference plane value is
identical for and applies to all responses. A settings conflict error is reported if no stimulus
channel is active. 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:RPLANE?"
Returned Format [:TDR:RESPonse<N>:RPLane] <value><NL>
RESPonse:TYPE
Command :TDR:RESPonse<N>:TYPE {CSINgle | CDIFf | CCOMmon | UDIFf | UCOMmon}
Use with differential mode or common mode measurements to select the type of measure-
ment for the indicated response. The value <N> is an integer, 1 through 4, that identifies the
response waveform.
The command arguments are defined as follows:
• CSINgle selects a calibrated single-ended response
•CDIFf selects a calibrated differential mode response
• CCOMmon selects a calibrated common mode response
• UDIFf selects an uncalibrated differential mode response
• UCOMmon selects an uncalibrated common mode response
Restrictions Software revision A.06.00 and above. TDR mode.
Example 10 OUTPUT 707;":TDR:RESPONSE1:TYPE CDIFf"
Query The query returns only the short form of the command. For example CSIN, CDIF, CCOM, UDIF, or
UCOM. The long form is not returned even if :SYSTem:LONGform is on.
:TDR:RESPonse<N>:TYPE?
Returned Format [:TDR:RESPonse<N>:TYPE] {CSINgle | CDIFf | CCOMmon | UDIFf | UCOMmon}<NL>
RESPonse:VAMPlitude?
Query :TDR:RESPonse<N>:VAMPlitude?
Queries the V amplitude value (V
ampl
)for calculating the impedance for TDR or TDT
responses. Use “RESPonse:VLOad?” on page 22-9 to return the value of V
load
. Use the follow-
ing equation for the calculation:
