6.1.3. Single frequency time mode
In this mode, a log is kept of the changes in
a single frequency over time. An example
is shown in the gure above. There are two
ways to select the frequency:
a) In the FFT mode, place the cursor on
the desired frequency (you may need to
change the SPAN in order to choose the
desired frequency), then change to the
Frequency Log mode.
b) Directly in the Frequency Log mode,
using the SPAN and FREQ functions.
With a SPAN of 400 Hz you can select
frequencies with 1 Hz resolution, with a
SPAN of 4 kHz with 10 Hz resolution, with
a SPAN of 40 kHz with 100 Hz resolution,
and with a SPAN of 400 kHz with 1 kHz
resolution.
Note that in this mode, even if you have selected a limit to obtain a value directly as a %,
only the RMS will be given and not the peak value.
