5.6.7 Measurement example: multi-sem measurement
The following measurement example demonstrates an SEM measurement for a signal
with multiple sub blocks.
A programming example demonstrating a SEM measurement in a remote environment
is provided in
Chapter 12.5.6.11, "Example: SEM measurement" , on page 959.
Test setup:
Signal generator settings (e.g. R&S FSV/A SMW):
Device Standard Center frequency Level Test model
SigGen 1 3GPP/FDD 900 MHz 0 dBm 1-16
SigGen 2 EUTRA/LTE 906.5 MHz 0 dBm 1_1_5MHz
Setting up the measurement
1. Preset the R&S FSV/A.
2. Set the center frequency to 903.25 MHz .
3. Set the reference level to 10 dBm with an offset of to 30 dB .
4. Press the [MEAS] key or select "Select Measurement" in the "Overview".
5. Select the "SEM" measurement function.
6. Select the "Sub Blocks" softkey and enter "Sub Block Count" of 2 .
7. For "Sub Block A", define the settings for the 3GPP/FDD signal:
● Set the "Center Frequency" to 900 MHz
● Select "MSR Settings".
● Set the "Base Station RF Bandwidth" to
5 MHz .
● Select "Apply to SEM".
