Perform an EMC Measurement
Perform an EMC Measurement
Please refer to the procedures below to perform an EMC
measurement (Option EMC required). This procedure contains the
primary four parts as below:
• Scan in CISPR band with CISPR RBW and peak detector
• Load a CISPR limit with pass/fail test
• Use peak search to locate the out-of-limit points
• Measure with quasi-peak detector in zero span
1 Press
Preset
(With
Preset Type
of
DFT
)
2 Press
[Freq] > {Start Freq} > [30] > {MHz}
to set the start frequency
at 30 MHz
3 Press
[Freq] > {Stop Freq} > [1] > {GHz}
to set the stop frequency at
1 GHz
4 Press
[Amplitude] > {Y axis unit} > {dBuV}
to set the Y axis unit to
dBuV
5 Press
{Attenuation} > [10] > {dB}
to set the attenuation to 10 dB
6 Press
[BW] > {File type} > [120 kHz CISPR}
to set the analyzer with
CISPR RBW
7 Press
{VBW} > [1] > {MHz}
to set the VBW wider than CISPR RBW
8 Press
[Trace/Det] > {Detector} > {Pos Peak}
to set the positive peak
detector.
NOTE
After these steps, you can save the instrument status to a *.STA file, and
store it in directory: /USER/STATE. Then it will be shown as one of the
softkey under [User] hardkey, which provides one-button access from the
front panel.
