17 I/Q software interface (Option R&S RTO6-
K11)
The option R&S RTO6-K11 "I/Q software interface" acquires modulated signals and
outputs I/Q data for further analysis using other software, for example, MATLAB.
Rohde & Schwarz provides the R&S®VSE vector signal explorer for analysis of I/Q
data on external computer.
In I/Q mode, the input signal is captured with a sample rate of 10 Gsample/s.
In addition to the I/Q data recording, the option also provides the NFC trigger type, a
specific trigger for near field communication analysis.
For specifications, see the R&S RTO6 data sheet.

17.1 I/Q mode
The I/Q mode is a special operating mode of R&S RTO6. In this mode, the usual ana-
lyzing tools (cursor, zoom, measurements, FFT and so on) of the oscilloscope are
deactivated. The instrument displays the magnitude of the I/Q vector to get an impres-
sion of the data before it is exported.
Triggering is performed on the input data before conversion to I/Q data, using the usual
R&S RTO6 trigger functionality. In case of complex input signals, the instrument trig-
gers on one component of the complex signal (I or Q) depending on the selected trig-
ger source.
To activate the IQ mode
1. Press the [App Cockpit ] key on the front panel.
2. In the "RF" tab, select "IQ".
3. In the "IQ Sampling" dialog, tap "Enable".
The instrument switches to I/Q mode, and the setup dialog for I/Q data recording is
shown.
17.2 I/Q sampling setup
Access: [App Cockpit] menu > "RF" tab > "IQ" > "IQ Sampling Setup"
In the "IQ Sampling" dialog box, you configure the complete I/Q sampling for real and
complex input signals.
