TDRT:SIGNal<m>:DATA:HEADer?
Returns the header of channel waveform data.
Table 24-17: Header data
Position Meaning Example
1 XStart in s -9.477E-008 = - 94,77 ns
2 XStop in s 9.477E-008 = 94,77 ns
3 Record length of one waveform 200000
4 Number of values per sample interval, is 1 1
Suffix:
<m>
.
1..3
1 = impedance Z (result of TDR measurement)
2 = reflection coefficient ρ (result of TDR measurement)
3 = pulse response h (result of TDT measurement)
Usage: Query only
TDRT:SIGNal<m>:DATA:VALues? [<Offset>], [<Length>]
Returns the data of the waveform points for transmission from the instrument to the
controlling computer. The data can be used in MATLAB, for example.
Without parameters, the complete waveform is retrieved. Using the offset and length
parameters, data can be retrieved in smaller portions, which makes the command
faster.
To set the export format, use
FORMat[:DATA]

1 = impedance Z (result of TDR measurement)
2 = reflection coefficient ρ (result of TDR measurement)
3 = pulse response h (result of TDT measurement)
Query parameters:
[<Offset>] Number of offset waveform points.
Range:
0 to m. Limit: n + m >= record length
Return values:
[<Length>] Number of waveform points to be retrieved.
Range:
1 to n. Limit: n + m >= record length
