LTE SRS Measurement

User Manual 1173.9628.02 ─ 16
The external attenuation value is also used in the calculation of the maximum input
power that the R&S
CMW can measure.
If a correction table for frequency-dependent attenuation is active for the chosen con-
nector, then the table name and a button are displayed. Press the button to display the
table entries.
In the Standalone (SA) scenario, this parameter is controlled by the measurement. In
the Combined Signal Path (CSP) scenario, it is controlled by the signaling application.

Carrier Aggregation Mode
This setting has no effect for SRS measurements. Only the PCC is evaluated, even if
carrier aggregation is active.
The parameter is only visible, if option R&S CMW-KM502/552 is available.
Band / Channel / Frequency
Center frequency of the RF analyzer. Set this frequency to the frequency of the mea-
sured RF signal to obtain a meaningful measurement result. The relation between
operating band, frequency and channel number is defined by 3GPP (see
ter 3.2.4.2, "Frequency Bands"
You can specify the RF frequency in two ways:
●
Enter the frequency directly. The band and channel settings can be ignored or
used for validation of the entered frequency. For validation select the designated
band. The channel number resulting from the selected band and frequency is dis-
played. For an invalid combination no channel number is displayed.
●
Select a band and enter a channel number valid for this band. The R&S
CMW cal-
culates the resulting frequency.
In the Standalone (SA) scenario, these parameters are controlled by the measurement.
In the Combined Signal Path (CSP) scenario, they are controlled by the signaling appli-
cation.

Frequency Offset
Positive or negative frequency offset to be added to the specified center frequency of
the RF analyzer.
In the Standalone (SA) scenario, this parameter is controlled by the measurement. In
the Combined Signal Path (CSP) scenario, it is controlled by the signaling application.
