R&S FSU
Firmware Release 4.61 SP3
11
E-33
For analyzers with IF Filter Model 03 or newer a VBW of 30MHz can be selected if the RBW is greater than
10 MHz. The hardware setting is identical to VBW of 10MHz (no VBW usage).
7. (V3.61) RS232 serial remote control
Since version 3.61 the instrument goes in remote mode rather than in local mode when a command is send
through the RS232 remote interface. This means the display disappears and the LOCAL softkey appears as
when the GPIB bus is used. To change between local and remote mode the commands @LOC and @REM
can be send to the instrument.
8. (V3.71) Harmonic measurement
The mixer level within the harmonic measurement is changed to -10 dBm.
The value update in the lower screen happens during the sweep and not only at sweep end.
9. (V3.81) Modifications to HP commands
- Command IP resets format to O3
- Reading a trace with TRA; TRB or TRC is possible even if trace is blank
- Great changes of span (e.g. from 2 GHz to 100 KHz) will not loose signal when marker track is on
- The R&S FSU has now a mixer level of -10dBm instead of -25dBm
10. (V3.91) The CCDF measurement result table is extended by 0.01% value.
11. (V3.91) New marker functions AUTO MAX PEAK and AUTO MIN PEAK.
12. (V3.91) HP emulation: HP Models 71100C, 71200C and 71209A are using 800 sweep points
13. (V4.01) Additional number of sweep points 201, 401, 801 and 1601.
14. (V4.01) HP emulation: Additional HP Models 8568A_DC and 8568B_DC using DC coupling.
15. (V4.01) HP emulation: GENERAL SETTINGS - GPIB menu extended by IF GAIN NORM / PULS
16. (V4.01) New spurious emissions measurement LIST EVALUATION
17. (V4.01) FS-K7: The THD Unit is selectable (dB / %) in the AM signal / AF spectrum result
18. (V4.01) New function MARKER FILE EXPORT.
19. (V4.01) Support for FSU-B73 added.
20. (V4.01) Signal Track: Enhanced sensitivity in marker tracking function.
The marker is now set to the signal peak after very single sweep. This only occurred in earlier versions if the
difference between signal peak and center frequency exceeded 20 % of the Resolution Bandwidth.
21. (V4.01 SP2) HP emulation: Behaviour of KSK and MKPK changed in single sweep mode.
The commands KSK (next peak) and MKPK NH|NL|NR (next high, next left, next right) do not perform a new
sweep in single sweep mode.
22. (V4.01 SP2) IF SHIFT B, additional shift for resolution bandwidth < 200 kHz.
23. (V4.11) Improved Firmware Update.
24. (V4.11) New enhancement label to indicate filter type.

28. (V4.11) Support for Power Sensor NRP-Z81 is available.
