Use an ARB generator if you wish to:
●
Utilize the flexibility of R&S WinIQSIM2 in configuring the signal properties
●
Re-use signal that you have once configured
●
Quickly alternate between signals with different properties (multi-segment files)
Use a real-time generator if you wish to:
●
Quickly re-configure signals and test the effects without loading a new waveform file
●
Generate signals with arbitrary length (e.g. for the transmission of long PRBS sequen-
ces)
●
Use dynamic features such as TPC sequences for WCDMA tests
4.3 Measurements
The R&S CMW500 provides several measurements for each of the supported network
standards or general purpose applications. All measurements are controlled in an anal-
ogous way. The following topics describe the principles of measurement control and
measurement results that are similar in many measurement contexts. For a sample ses-
sion refer to
.
4.3.1 Measurement Control
Measurements can be in the "RUN", "RDY", or "OFF" states. In the default configuration,
all measurements are switched off; no results are available. The measurement state is
shown in the measurement control softkey.
► To turn the measurement on or off, select the measurement control toggle softkey
and press ON | OFF or RESTART | STOP. It is not necessary to select the mea-
surement control softkey.
The behavior of the measurement control softkey depends on the "Repetition" mode
selected in the configuration dialog:
●
If the measurement is turned on in "Single-Shot" repetition mode, it enters the "RUN"
state and returns to "RDY" as soon as a single-shot result has been acquired.
●
If the measurement is turned on in "Continuous" repetition mode, it remains in the
"RUN" state until it is turned off explicitly using the measurement control softkey or
the front panel keys (ON/OFF or RESTART/STOP).
