Mirrored
This selection is similar to
Centered
, but is mirrored around the central
0
position. Note that this yields increased visibility for null detection, at the
cost of not knowing polarity.
These settings may be altered by:
1. Pressing the
DISPLAY SELECT 3
key.
2. Using the
é
or
ê
keys to change the selection containing the cursor character.
3. Using the
ç
or
è
keys to move the cursor character between the three
selections.
4. Pressing the
ENTER
key when all three selections are made.
Additional Application Examples
Select the
Set Defaults
menu item under the
SETUP
key prior to configuring
measurements for a specific application, to ensure the configuration is starting from
a known condition.
The following example procedure applies:
•
If you need to measure harmonic content, amplitude, or phase while tracking the
fundamental frequency
•
If you need to measure wideband amplitudes synchronously with the input
signal—a requirement when below 1kHz.
Ø
To measure signal content of harmonics, amplitude, phase, and sync:
1. Set the
FUND: RANGE
menu selection to the desired range of fundamental
frequencies. You may set any range of frequencies within the
0.0005Hz
to
100kHz
range, with a limit of a
128:1
range.
•
More stable harmonic measurements will result if you set the frequency
range to a ratio as low as possible, such as, 2:1. For example, set range from
40 to 80Hz for 60Hz measurements.
•
Under situations where the signal contains significant non-harmonic content,
such as, asynchronous PWM or noise, or significant low order harmonic
content,
—Then—
Set the frequency for this range to as low as possible. Note that this lowest
position is just above the expected highest fundamental frequency.
2. Set the
From:
menu selection to obtain the fundamental frequency only from one
of the inputs being used. Choose the input having the largest signal with the least
extraneous signal content.
