The following control elements select the power meter type and its connection:
 Name is an optional, arbitrary name associated with the power meter. Names appear in the power
meter lists in the External Power Meters tab and in the selection dialogs for received signals
(measurements and power calibration). If no name is specified, the power meters are listed as
Pmtr 1, Pmtr 2...
 Interface selects an interface/protocol type for the connection. In addition to the GPIB0 and VXI-
11 interface types (for devices connected to the IEC Bus or LAN1/2 connectors on the rear panel
of the analyzer, respectively), the analyzer supports any Other interface supported by the installed
VISA library.
 GPIB Address (or Hostname or IP Address or Resource String, depending on the Interface
selection) contains the address for the current interface type. GPIB addresses must be unique for
all devices connected to the GPIB bus (range: 0 to 30), GPIB and IP addresses must agree with
the entries in the VISA library. For an Other interface type, the input field contains the Resource
String from the installed VISA library.
 Driver contains a list of all supported power meter driver types. The names in the list are identical
with the name of the power meter configuration files (*.pwm) stored in the resources\extdev
subdirectory of the analyzer's program directory. For detailed information about the configuration
files refer to section Configuration Files.
 Identify Type sends an identification query (*IDN?) to the specified device address in order to
identify the power meter type and select an appropriate configuration file. An error message is
displayed if the identification fails. See also Naming Conventions for Automatic Detection.

External Generators
Configures external generators with their connection type and device address.
Use of external generators, examples
An external generator can serve different purposes:
 Extended measurement functionality: Each external generator represents an additional source
port. External generators increase the number of RF input signals for the DUT. A typical example
is a mixer measurement with a 2-port analyzer, where an external generator provides the LO input
signal.
