Configuration Setup
45
•
You want to perform a spectral analysis of the input signal(s), rather than
harmonic analysis.
Note:
When performing a spectral analysis, set the fundamental frequency to
the desired frequency step between available spectral points, set the RBW ratio
to 1, and set the maximum harmonic to the number of spectral points, desired.
Fundamental Frequency Range
When the fundamental is not fixed, the
Fundamental Frequency Range
menu is
active. The menu line
Fund: 40.0 – 500 Hz
allows you to set a frequency range for a
measured fundamental frequency.
•
The default frequency range shows on the display as
40Hz to 500Hz
. You may
set any range of frequencies within the
0.0005Hz to 100kHz
range, with a limit
of a
128:1
range.
•
When in-phase precision is required, or where harmonic distortion is present, it
is beneficial to reduce this to a
2:1
range around the nominal fundamental
frequency. An example of this is
40 to 80Hz
.
•
When specifying a fundamental frequency range, consider that the instrument
will take the lowest frequency component having a signal of greater than 5% of
range, as its fundamental. If there is signal having a sub-fundamental frequency
component of any significance, then the exclusion of that frequency from the
selected range will substantially eliminate its effect on the measurement.
•
If your instrument requires signal measurements having fundamental frequencies
beyond the 40Hz to 500Hz range, or other requirements to accommodate
abnormal measurement situations;
—Then—
Use the
SETUP
key to enter a configuration reflecting your instrument’s needs.
Note that previous configurations may be stored and recalled using the
STORE
and
RECALL
keys.
Fundamental Source
When the fundamental frequency is not fixed, the
From:
menu line becomes active.
The
Fundamental Source
menu sets an input, or a set of inputs. The fundamental is
based on the measured frequency of the input(s) set by this menu line.
The source applies when:
•
An input is added to or removed from the list by pressing the respective
INPUT
key.
•
The default is set to
AUTO-SELECT
between all inputs.
