The default settings of the R&S
CMW generally ensure a forward signal with suitable
characteristics for connection setup. The most important settings can be modified
directly in the main view.
Performing measurements
The required settings vary depending on the measurement to be performed. However,
the general procedure outlined below is applicable to most measurements.
1. Connect your MS to the R&S
).
2. Open the "CDMA2000 Signaling" firmware application.
3. Configure the signaling application according to the test to be performed.
4. To turn on the forward signal, press ON | OFF and wait until the "CDMA2000 Sig"
softkey indicates the "ON" state.
5. Switch on the MS.
The MS under test synchronizes to the forward signal and registers. Due to the
CDMA2000 3GPP2 standard an MS registration within a CDMA2000 network could
take 12 or up to 20 seconds.
6. Click the "Connect 1st SO" softkey to establish a connection.
Note the connection states displayed in the main view and wait until the MS state
indicates "Connected". In connected state, the main view provides also connection
details and MS information.
7. To switch to the measurement application, press the "Go to..." softkey. The
"CDMA2000 RX Measurement" is provided by the CDMA2000 signaling firm-
ware application. The "CDMA2000 Multi Evaluation" measurements are available
as option R&S CMW-KM800.
In the latter case, the softkey also selects the combined signal path scenario in the
measurement. The scenario allows to use the measurement in parallel to the sig-
naling application and configures compatible measurement settings (e.g. RF and
trigger source settings).
8. Configure and start the measurement.
Trigger Source for Multi Evaluation Measurements
In the "CDMA2000 Multi Evaluation" measurement use a "CDMA2000 Super Frame"
trigger source to obtain valid transmit time error results.
Checks in case of failed registration
If the registration of the MS fails, check the following R&S
CMW settings:
●
The "Expected Power" must be in accordance with the reverse signal power.
●
The "Output Channel Power" must be sufficient so that the MS under test can
receive the forward signal.
●
The "RF Channel" of the generated forward signal must be within the RF Channels
supported by the MS.
