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].
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)
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
Usage: Query only
22.21 I/Q software interface (option R&S RTP-K11)
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.
