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 14.5.7.11, "Example: SEM Measurement"
Test setup:
Signal generator settings (e.g. R&S
FSW 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
FSW.
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".
