Conducting EMF spectrum measurements
After you have configured test parameters as described in the “Configuring test parameters” on page 765,
you can start your EMF measurements. If you log your measurement, you can play back using the EMF
Replayer. For more information on saving logging data, see “Logging EMF spectrum data” on page 771.
Procedure
1
Press the
MEASURE SETUP
hot key.
2
To specify the amount of measurement time that you want the instrument to stay for on each
axis:
Press the
Dwell Time
soft key.
Enter a value in seconds between one and 60.
Press the unit soft key or the
ENTER
hard key.
3
To specify the amount of measurement time that you want the instrument to stay for on all three
axes in order to display current and accumulated EMF power:
Press the
Measurement Time
soft key.
Enter a value in minutes or in seconds. You can set this up to 30 minutes.
Select the unit from the choices:
Minute
and
Second
.
NOTE
The Isotropic EMF Power is the current or the latest average power measured with three
axes for the specified dwell time for the axis while the Accumulated Isotropic EMF Power
is the average, maximum, and minimum power taken from the number (n) times of
measurements.
4
To specify the number of EMF measurements that you want to make:
Press the
# of Measurement
soft key.
Enter a value. Depending on your settings for Dwell Time and Measurement Time, you can
set this up to 600.
Press the
Enter
soft key or the
ENTER
hard key.
NOTE
The dwell time, measurement time, and number of measurement are correlated based on
the equation of
“# of Measurement = Measurement Time / (Dwell Time x 3)
”. For
example, if you set the Dwell Time to 60 seconds and the Measurement Time to 30
minutes, you can enter “10” for the # of Measurement”.
5
To start the measurement, toggle the
Measurement
soft key and select
On
.
The instrument displays measurement results on the screen. Figure 464 is an example.
