1 Preparing the I/Q Data Recorder for Use
The R&S IQR is a fast recording and replay device for digital I/Q data which is transfer-
red over the R&S Digital I/Q Interface. The R&S Digital I/Q Interface is supported by
many Rohde & Schwarz instruments. A typical application scenario is a drive test
where an R&S TSMW "Universal Radio Network Analyzer" is used as a network scan-
ner, providing an I/Q baseband data stream which is recorded by the R&S IQR. The
subsequent analysis (e.g. using an R&S FSV spectrum analyzer) is based on the raw
I/Q data with no loss of information. You can also feed the recorded I/Q data stream to
an appropriate signal generator (e.g. an R&S SMU200A) in order to re-generate the
modulated RF signal.
Rohde & Schwarz provides two different I/Q Data Recorder models which essentially
differ in the recording and data transmission speed.
●The R&S IQR20 supports data rates up to 20 megasamples per second (MSa/s),
corresponding to 80 MByte/s.
●The R&S IQR100 supports data rates up to approx. 99.5 MSa/s (with R&S IQR-
B110 up to 75 MSa/s), corresponding to 400 MByte/s.
Both instruments can be combined with the following memory pack options:
●R&S IQR-B010, "HDD Module 1 TB, 80 MByte/s"
●R&S IQR-B020, "HDD Module 2 TB, 80 MByte/s"
●R&S IQR-B110, "SSD Module 1 TB, 300 MByte/s"
●R&S IQR-B109F, "SSD Module 0.9 TB, 400 MByte/s"
●R&S IQR-B119F, "SSD Module 1.9 TB, 400 MByte/s"
●R&S IQR-B138F, "SSD Module 3.8 TB, 400 MByte/s"
To use the full data rate of the R&S IQR100, one of the SSD options R&S IQR-B109F,
R&S IQR-B119F or R&S IQR-B138F is required.
The present chapter gives all information that is necessary to put the instrument into
operation and presents an overview of the front panel controls and connectors of the
R&S IQR.
Chapter 2, Basic R&S IQR Operation outlines typical application examples for the I/Q
Data Recorder. The following chapters provide reference and background information
about the use of the Graphical User Interface (GUI) and about remote control.

Figure 1-1: R&S
IQR startup screen
If the previous session was terminated regularly, the R&S IQR application uses the last
instrument configuration.
Once the startup procedure has been terminated, the "Player" main dialog is displayed.
See Chapter 2.4, "Replaying Data", on page 36.
To shut down the R&S IQR, proceed as follows:
1. Press the standby toggle switch to save the current instrument configuration, close
the R&S IQR application, shut down the Windows® XP Embedded operating sys-
tem and set the instrument to standby state. You can also perform this procedure
step by step like in any Windows® session.
2. If desired, set the AC power switch to position 0 (Off).
Standby state
It is strongly recommended to switch the R&S IQR to standby state before disconnect-
ing it from the AC supply. If you set the power switch to 0 while the R&S IQR applica-
tion is still running, you will lose the current settings. Moreover, loss of program data
cannot be excluded if the application is terminated improperly.

1.5 Instrument Control
The R&S IQR can be controlled in the following ways:
●Using the touchscreen display. The functions of the Graphical User Interface (GUI)
are described in Chapter 5, "General and Administrative Tasks", on page 79.
●With a remote desktop connection through a Local Area Network, see Chap-
ter 10.2, "Remote Operation in a LAN", on page 177
●With an external monitor in combination with a mouse and/or keyboard, see Chap-
ter 1.6.3, "Connecting a Monitor", on page 21.
1.6 Connecting External Accessories
The equivalent USB ports on the front and rear panel of the R&S IQR can be used to
connect a variety of accessories:
●A mouse simplifies operation of the instrument using the controls and dialogs of the
Graphical User Interface (GUI).
●A keyboard simplifies the entry of data.
In addition the R&S IQR provides interfaces for monitor connection and network inte-
gration:
●An external monitor shows the magnified Graphical User Interface (GUI) with all
diagram areas and controls.
●A LAN connection can be established in order to access the hard disk or control
the tester from an external PC.
1.6.1 Connecting a Mouse
A USB mouse can be connected to one of the Universal Serial Bus (USB) connectors
on the front panel or on the rear panel.
The mouse is detected automatically when it is connected. It is safe to connect or dis-
connect the mouse while the R&S IQR is in ready state.
Risk of data loss
Do not connect or disconnect the mouse while data is being recorded or replayed.
