12.2.2
Selecting the Measurement Bandwidths for EMI Measurements
The receiver mode adds 6 dB resolution bandwidths to the 3 dB resolution bandwidths
already available in other operating modes. The 6 dB bandwidths are special band-
widths that are necessary for measurements according to CISPR16.
If automatic selection of the CISPR bandwidth is on, the R&S Spectrum Rider selects
an appropriate CISPR bandwidth, depending on the receive frequency.
●
Frequencies from 9 kHz to 150 kHz: 200 Hz CISPR bandwidth
●
Frequencies from 150 kHz to 30 MHz: 9 kHz CISPR bandwidth
●
Frequencies from 30 MHz to 1 GHz: 120 kHz CISPR bandwidth
You can also select a 3 dB or 6 dB bandwidth manually.
1. Press [BW] key.
2. Select "Manual RBW" softkey to select a 3 dB bandwidth.
3. Alternatively, select "Manual CISPR BW" softkey to select a 6 dB bandwidth.
The R&S Spectrum Rider opens an input field to define the CISPR bandwidth.
4. Select the bandwidth with the rotary knob or by entering the corresponding num-
ber.
5. Select "Auto CISPR BW" to select the 6 dB bandwidth automatically according to
the list above.
12.2.3
Defining the Measurement Time
The measurement time is the time that the R&S Spectrum Rider collects data at each
measurement frequency to calculate the results for that frequency according to the
detector you have selected.
You can define a measurement time between 5 ms and 1000 s.
1. Press [SWEEP] key.
2. Select "Meas Time" softkey.
The R&S Spectrum Rider opens an input field to define the measurement time.
3. Define the measurement time.
