R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
• Max Transfer Rate: Maximum interface clock rate to transfer the I/Q data.
Basic Settings
• Connection Protocol: State of the connection protocol. The analyzer is able to
communicate with the sending or receiving device.
• PRBS Test Deskewing: An alignment process is started if the output or input of the
R&S FSQ-B17 is connected to a digital baseband source/sink. The current state
of this process is shown here. Possible states are "not yet started", "failed" or
"passed".
This softkey is only available with option R&S FSQ-B17.
Remote command: INP:DIQ:CDEV?
OUTP:DIQ:CDEV?
EX-IQ BOX The EX-IQ BOX softkey opens a dialog to configure an R&S EX-IQ-Box connected
to the digital baseband input or output.
This softkey is only available with option R&S FSQ-B17.
For more information refer to the manual for option R&S FSQ-B17.
4.6.3.4 RF Preamplifier
To improve the noise figure, a low-noise preamplifier with variable gain at the RF
input can be switched into the signal path.
PREAMP The PREAMP softkey switches the preamplifier on or off and activates the entry of
the preamplifier gain. The preamplifier is switched off by pressing the softkey again.
The only possible value with option el. attenuator (B25) is 20 dB.
Remote command: INP:GAIN:STAT ON
'Switches the 20 dB preamplifier on.
The PREAMP softkey is only available with option el. attenuator (B25) or option
low noise preamp (B24).
4.6.3.5 Transducer
Activating Transducer Factors
The TRANSDUCER softkey opens a submenu enabling the user to activate or deactivate
defined transducer factors, to generate new transducer factors or to edit existing
ones. A table with the transducer factors defined is displayed.
As soon as a transducer is activated, the unit of the transducer is automatically used
for all the level settings and outputs. The unit cannot be changed in the AMPT menu
since the R&S FSQ and the transducer used are regarded as one measuring instrument.
Only if the transducer has the unit dB, will the unit originally set on the
R&S FSQ be maintained and can be changed.
If a transducer factor is active, TDF is displayed in the enhancement labels column.
After all transducers have been switched off, the R&S FSQ returns to the unit that
was used before a transducer was activated.
