Event Trigger
The signaling application is able to raise events that other application could use as trig-
ger signals. This mechanism is used for OLTR measurements (option R&S CMW-
KM800) in combined signal path mode, where the event triggers mark the start of an
OLTR evaluation interval.
Paging Channel Frame Trigger
Trigger event at the beginning of each paging channel frame (20.00 ms).
Power Control Group Trigger
Trigger event at the beginning of each Power Control Group on the Forward Traffic
Channel (1.25 ms).
Periodic Pulse Trigger
Periodic trigger event raised every 2 seconds.
Sync Channel Superframe Trigger
Trigger event at the beginning of each Sync Channel Superframe (80 ms) suitable for
the TX multi evaluation measurements especially transmit time error tests.
Sync Channel Frame Trigger
Trigger event at the beginning of each Sync Channel Frame (26.67 ms).
4.2.17 RX Measurements
The "RX measurement" results are displayed in a tabbed style.
The state of the signaling application can be observed from within the "RX measure-
ment" view:
A configuration dialog is common for all RX measurements. To access the RX mea-
surement specific configuration tree select "RX Meas..." and "Config..." softkeys.
4.2.17.1
Frame Error Rate (FCH / SCH0) Measurement
The CDMA2000 signaling RX measurement tests the complete signal path from the
R&S
CMW to the DUT and back. To this end the MS is set to test loop operation or test
data service, where it returns the received and decoded data blocks back to the instru-
ment. The R&S
CMW compares its output signal with the received signal to derive the
measurement results.
MS test loops and frame error rates for conformance tests are specified in 3GPP2
C.S0043.
