2. To adjust the instrument settings to the current input signal automatically, press
[AUTOSET].
3. Select the "FFT" mode.
4. Select the "Frequency Span" setting and determine which sample frequency you
require ("Max" is the highest).
5. Select the "Window" type according to the signal characteristics that are most rele-
vant for your measurement task (see "Window type" on page 113).
6. Select the "Channel Bandwidth" setting and define the frequency limit of the spec-
trum diagram. Frequencies above the selected limit are removed to reduce noise at
different levels.
7. To switch to a logarithmic frequency scaling, select "X-Scaling": "Logarithmic".
8. To start and stop FFT analysis, press the [RUN STOP] key.
6.1.4 FFT Mode Settings
Access: "FFT" menu
Additional settings for horizontal (time) scaling and data acquisition are available for
FFT mode and directly accessible via the FFT menu. For a description, see:
●
"Time Scale" on page 46
●
"Acquisition Mode" on page 48
●
"Sampling Rate C1 - C4" on page 49
Furthermore, the history function can be used to perform FFT analysis on stored data,
see Chapter 4.7, "History (Option R&S RTH-K15)", on page 98.
