Configuration Files for External Devices
Operating Manual 1145.1084.12 – 30 1157
For command synchronization, the POWERMEASUSEOPC and GENERATORUSEOPC mechanisms
must be used.
 Unless otherwise specified by the optional POWERMEAS_COMMANDPREFIX and
GENERATOR_COMMANDPREFIX parameters, a *CLS command is prepended to every SCPI-
command.
Naming Conventions for Automatic Detection
The configuration files are stored in the Network Analyzer\resources\extdev subdirectory of the
analyzer's installation directory. Power meter configuration files have a file extension *.pwm; generator
files an extension *.gen. A correct file name is essential for automatic detection of the external devices.
The names of the pre-installed configuration files are composed of the <device type> identifier in the
*IDN? string and the extension. The general format of the *IDN? string is:
"<manufacturer>,<device type>,<serial number>,<firmware version>
Example: "Rohde&Schwarz,SMU200A,1141.2005k02/102753,2.1.72.0-02.05.222.34"
--> The configuration file name is SMU200A.gen.
The analyzer also recognizes similar file names, provided they fulfil the following conditions:
 The filename and the model name match until the first numerical digit (e.g. SMU222A.gen instead
of SMU200A.gen).
 The filename contains the model name (e.g. R&S_SMU200A.gen instead of SMU200A.gen).
 The model name contains the file name (e.g. SMU200.gen instead of SMU200A.gen).
The analyzer automatically complements a missing <serial number> in the *IDN? string.
Power Meter Parameters
The following parameter set is used to control external power meters from the network analyzer.
The "mandatory" parameters must be included in every power meter configuration file; see General
Rules for Configuration Files.
