4.1 Unpacking the Instrument
Check the equipment for completeness using the delivery note and the accessory
lists for the various items. If you notice any damage, immediately contact the carrier who delivered the instrument.
Packing material
Retain the original packing material. If the instrument needs to be transported or shipped later, you can use the material to protect the control elements and connectors.
Risk of instrument damage during transportation and shipment
Insufficient protection against mechanical and electrostatic effects during
transportation and shipment can damage the instrument.
●
Always make sure that sufficient mechanical and electrostatic protection
is provided.
●
When shipping an instrument, use the original packaging. If it is not
available, allow for sufficient padding to prevent the instrument from
moving around inside the box. Pack the instrument in antistatic wrap to
protect it from electrostatic charging.
●
Secure the instrument to prevent any movement and other mechanical
effects during transportation.
The carrying handles are designed to lift or carry the instrument. Do not
apply excessive external force to the handles.
4.2 EMI Suppression
To suppress generated Electromagnetic Interference (EMI), operate the instrument only while it is closed, with all shielding covers fitted. Note the EMC classification in the specifications.
EMI Suppression
Page 13
Preparing for Use
R&S®IQW
11Getting Started 1178.6027.02 ─ 02
Use appropriate shielded cables to ensure successful control of electromagnetic
radiation during operation, especially for the following connector types:
●
Output connectors for reference signals (rear panel, REF IN / OUT): Use double-shielded RF cables and terminate open cable ends with 50 Ω.
●
USB: Use double-shielded USB cables and ensure that external USB devices
comply with EMC regulations.
●
LAN: Use CAT6 or CAT7 cables.
Observe the additional connector, cable, and cable length requirements in Chap-
ter 5.1, "Front Panel Description", on page 15 and Chapter 5.2, "Rear Panel
Description", on page 17.
4.3 Connecting a Power Supply
The I/Q Wideband Recorder is automatically adapted to the AC supply voltage.
The supply voltage must be in the range 100 V to 240 V; 50 Hz to 60 Hz. The
mains connector and power switch are located at the rear panel.
Connect the I/Q Wideband Recorder to the AC power source using the AC power
cable delivered with the unit. The maximum and typical power consumption of the
I/Q Wideband Recorder is listed in the specifications.
4.4 Connecting External Devices
The equivalent USB ports on the front and rear panel of the R&S IQW can be
used to connect various 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.
A LAN connection can be established to access the hard disk or control the tester
from an external PC.

Display
The R&S IQW is equipped with a touchscreen display. It is also possible to control the instrument via mouse and/or keyboard. Both can be connected to the
USB connectors on the front panel.
Standby Key
The standby key connects/disconnects all internal modules of the I/Q Wideband
Recorder to/from the DC supply voltages generated by its internal power supply.
Power LEDs
The Power LEDs indicate whether the I/Q Wideband Recorder is ready to operate
(LED "PWR" lights green) or in standby state (LED "Standby" lights orange).
The LEDs do not light when the AC power switch on the rear panel is in position 0
(Off).
USB 2.0 Connectors (2x)
The two USB 2.0 ports (type A, master USB) can be used for connecting external
devices as keyboard, mouse or other devices. Additional USB 2.0 connectors are
located on the rear panel of the I/Q Wideband Recorder.
USB 3.0 Connector (1x)
The USB 3.0 port (type A, master USB) can be used for connecting external storage devices or data sticks. Additional USB 3.0 connectors are located on the rear
panel of the I/Q Wideband Recorder.
The length of the connecting USB cables should not exceed 1 m. The maximum current per USB port is 500 mA. See also Chapter 4.2, "EMI Suppres-
sion", on page 10. To avoid disturbances, do not connect or disconnect
USB devices while data is being recorded or replayed.
Cartridge LEDs
The LED "State" is currently not used and always off. The LED "Act." indicates
the activity of the cartridge. It flashes, when the cartridge is in use (read/write
operations or at initialization at system start), otherwise it is off.

the operating mode of the source instrument; refer to the specifications for details.
Risk of data loss
Do not remove the memory pack while the R&S IQW is in ready state, or
while data is recorded or replayed. Always switch the instrument to standby
(or turn the power off) before you remove the memory pack.
Backups of recorded data
The solid state drives in the memory packs have a limited useful life,
depending on the number of recording cycles and their repetition rate. For
details, refer to the R&S IQW specifications. To prevent loss of valuable
data, perform regular backups using the archiving function.
