3. If the fundamental frequency is above 500Hz, or the default 50kHz filter cutoff
frequency is undesirable,
—Then—
Change the
Filter:
menu selection to
LOW-PASS FILTER CUTOFF
FREQUENCY
.
4. In the
Max Harmonics:
menu selection set the harmonic to
50,
or if no
harmonic analysis is required, set it to
0
.
5. The default
Fundamental
÷
BW:
selection (2) does not require changing.
Ø
To perform spectral analysis of the input signal.
Note:
For optimum results use an FFT type setting of Windowed.
1. Set the
Fund:
menu selection to
Fund: Fixed
, and set the frequency to the
required frequency resolution for the spectral analysis.
2. Set the
Min Period:
menu selection to the fastest desired update interval. We
recommend the longer time between 250mS or 4 periods of the frequency
entered in step 3 of measuring signal content regarding setting minimum period.
3. Set the
Filter:
menu selection to the highest frequency desired to be included in
the spectral analysis.
4. Set the
Max Harmonics:
menu selection to the number of spectral analysis
points required. Note that the highest frequency within the spectral analysis is
the frequency entered in step 1. above, times the maximum harmonics.
5. Set the
Fundamental
÷
BW:
selection to 1.
Ø
To measure wideband amplitudes over a known period of time:
Example:
when amplitudes are asynchronous to the input signal
1. Set the
Fund:
menu selection to
Fund:Fixed
, and set a frequency of 10kHz.
This sets the resolution of the measurement to 100
µ
s.
2. Set the
Min Period:
menu selection to the desired measurement interval. Note
that any period between 1mS and 100000S may be entered.
3. If the default 50kHz filter cutoff frequency is undesirable,
—Then—
Change the low-pass filter cutoff frequency. Refer to the
Filter:
menu.
4. Set the
Max Harmonics:
menu selection to 0.
The instrument will downrange at 10mS intervals if autorange is enabled. We
recommend you use a fixed input range if the signal contains more than 5% content
(including amplitude modulation) at frequencies below 100Hz.
