R&S ESU Preparing for Use
Connecting External Devices
3. If you no longer need the memory stick or if you want to transfer files to another computer,
simply disconnect the memory stick. Windows XP will automatically deactivate the driver. If
the drive is still selected in Explorer, an error message will appear indicating that the drive
is no longer available.
2.3.6 Connecting External Generators
The External Generator Control option (R&S FSP-B10) allows you to operate a number of
commercially available generators as a tracking generator on the R&S ESU. When suitable
generators are used, the R&S ESU thus allows scalar network analysis to be performed also
outside the frequency range of the internal tracking generator. Appendix
“External Generator
Control” provides a list of generators supported by the option R&S FSP-B10.
The following figure shows the test setup:
The generator is controlled via the – optional – second GPIB interface of the R&S ESU
(= IEC2, supplied together with the option). With some Rohde & Schwarz generators, it is also
controlled via the TTL synchronization interface that is contained in the AUX CONTROL
interface of the R&S ESU.
• Using the TTL interface allows you to attain significantly higher
speeds than possible with a pure GPIB control, because the
frequency switching mechanism of the R&S ESU is directly coupled
to the frequency switching mechanism of the generator.
• To increase measurement accuracy, use a shared reference
frequency to operate the R&S ESU and the generator. If no
independent 10 MHz reference frequency is available, connect the
reference output of the generator to the reference input of the
R&S ESU and use
SETUP – REFERENCE EXT to configure the
R&S ESU to implement the external reference.
