User Manual 1173.9463.02 ─ 02
The number of tasks that the instrument can service in parallel depends on the number
of independent paths. The R&S CMW500 can be equipped with up to 2 independent
input/output paths.
System resource conflicts
In addition to the hardware resources required for TX and RX paths, other system resour-
ces may cause limitations: memory size, possible connections between modules (e.g.
trigger lines, I/Q data lines etc.)
Software license key conflicts
Many R&S CMW500 features must be enabled using a software license key. To be run
in parallel, several measurements of the same type may require several active software
license keys. A resource conflict arises whenever the required number of software options
is not available.

Monitoring States of Tasks
The state of each task can be queried with commands of the following types:
FETCh:<Meas_FWA>:<Measurement>:STATe?
FETCh:<Meas_FWA>:<Measurement>:STATe:ALL?
SOURce:<Gen_FWA>:STATe?
SOURce:<Sig_FWA>:STATe?
SOURce:<Sig_FWA>:STATe:ALL?
For a detailed description see
.
Example 1: Conflicting generator and signaling applications
Command
Comment
SOURce:<Gen_FWA 1> ON
SOURce:<Gen_FWA 1>?
Switch on the first generator and query its state. After hardware
adjustment, the response is
ON
, i.e. the generator is running and
an output signal is available.
SOURce:<Gen_FWA 2> ON
SOURce:<Gen_FWA 2>?
Switch on the second generator and query its state. Again, the
response is
ON
, i.e. the generator is running.
SOURce:<Gen_FWA 1>?
Check the state of the first generator. The generator state should
be
OFF
, i.e. the second generator has replaced the first genera-
tor.
Signaling applications behave like generators and can replace each other. Both are not
replaced by measurements.
Example 2: Conflicting measurements
Two conflicting measurements will be queued; the first one is set to single-shot mode;
see examples in section
