Frame Error Rate (FER) measures the percentage of frame errors over the total num-
ber of frames received. The R&S
CMW monitors the Fundamental Channel (FCH) and
Supplemental Channel 0 (SCH0).
The actual size of the transmitted data blocks during a TDSO frame depends on the
multiplex sublayer command.
FER measurement requires option R&S CMW-KS810 (Signaling Advanced)
Test Procedure
A "RX Measurement FER" involves the following stages:
1. Connect your MS and establish a connection with a loopback service option or test
chapter 4.3.8.1, "Miscellaneous Service Configuration "
on page 547); wait until the R&S
CMW has entered the "Connected" state. For
details refer to
chapter 4.2.2, "Initiating Signaling Tests"
2. Open the "RX Measurement FER FCH/SCH0" and press "ON | OFF" to start the
measurement.
3. Wait until the R&S
CMW has sent the specified number of test packets and read
the results from the FER view.

RLP and IP Statistics
The RLP measurement evaluates the data flow between DUT and R&S
CMW using
packet data service option SO33 (see
chapter 4.2.10.4, "Packet Data Service"
on page 487). The measurement results consist of RLP frame counters, PPP total
bytes and the data rate in both reverse (Rx) and forward (Tx) direction. The results are
available and constantly updated while a PPP connection is active and the measure-
ment is switched on.
