3. Configure both signaling FWAs to the required RF frequencies and band classes
4. Apply time settings as described in

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.
The measurement is especially suitable to assess the characteristics and the perform-
ance of the MS receiver at low RF power levels. Because of the higher signal level,
transmission errors produced on the way back (from the MS to the instrument) can
usually be neglected. However, frames destroyed on the way back are detected in a
cyclic redundancy check (CRC) and counted. They are not taken into account in the
calculation of transmission errors.
Established call required
The RX measurement "RX Meas FER FCH" requires a connected loopback call (ser-
vice options 2, 9 or 55) or a test data call (SO32).
The RX measurement "RX Meas FER SCH0" requires a test data call (SO32) to test
the high data rates.
