Making MSR Measurements
MSR Downlink Signal Measurement

Common Measurement Procedure (Downlink)

The following procedures are common and need to set up for all measurements.
Step
1. Enable the MSR
measurements.
2. Preset the Mode.
3. Select the operating
band.
4. Set the carrier
reference frequency.
5. Set the RF band width.
6. Configure the carriers.

Band 8-14, Band 8
. Then
the OB Start Freq is
automatically changed to 925
MHz and OB Stop Freq is 960
MHz.
FREQ Channel
Press ,
Carrier Ref Freq, 942.5
MHz
.
FREQ Channel
Press ,
Carrier Setup
, Carrier Conf
Presets, Max BS RF Bandwidth,
35 MHz.
Then press MSR Test Config,
TC4c(FDD). And the arrow in the
key turns from hollow to solid.
Press TC4c(FDD) again so the
menu under it displays. Then
enter 2 for Max LTE FDD
Carriers, Max W-CDMA Carriers
and Max GSM/EDGE Carriers.
Select 5 MHz (default value) for
LTE FDD BW. In LTE FDD
Location, select Upper (Higher
than W-CDMA) (default value)
for the location of LTE FDD
carriers.
Notes
Only do this to return the measurement settings to a
known state for all measurements in the MSR mode.
Operating band affects the frequency ranges and
limits of Spectrum Emission Mask and Spurious
Emission measurement.
When in Auto mode, the Band Category is
automatically set depending on Band selection
In MSR mode, the measurements are implemented
based on carrier center frequency and its bandwidth.
,
Center Frequency is defined by Carrier Ref Freq and
Center Freq Offset and available in three
measurements, Monitor Spectrum, IQ Waveform and
Power Stat CCDF.
Carrier Conf Presets are defined based on 3GPP TS
37.104 standard configuration. It is used to quickly
configure the carriers. If you use specified carriers,
Carriers and Configure Carriers under Carrier Setup
is used for manually setup.
You can also use the parameters under Carrier Setup
and Configure Carriers to manually configure the
carriers.
