Configuration Files for External Devices
Operating Manual 1145.1084.12 – 30 1156
Time
Description
Value
T1
Pulse duration of /EXTERNAL TRIGGER
Minimum value: 1 μs
T2
Response time of /PASS FAIL STROBE
1 μs
T3
Pulse duration of /PASS FAIL STROBE
1 μs
T4
Pulse duration of /SWEEP END
12 μs
The timing of the data port signals and the input/output signals is as follows:
 The low pulse of the /WRITE STROBE signal occurs approx. 0.1 μs after a value is written to the
output ports A to D. The pulse duration of the /WRITE STROBE signal is 1 μs.
 The low pulse of the /OUTPUT 1 or /OUTPUT 2 signals (if enabled) occur approx. 0.4 μs and 0.6
μs after the falling edge of the /INPUT 1 signal. The minimum pulse duration of the /INPUT 1
signal is 1 μs.
Configuration Files for External Devices
The network analyzer provides configuration files for many external power meters and generators. When
an external device is configured in the System Configuration dialog, the analyzer loads its configuration
file and accounts for the settings made as far as possible.
The following sections describe the configuration files and their parameters.
General Rules for Configuration Files
The following rules apply to power meter and generator configuration files.
 All configuration file entries may appear in arbitrary order.
 A command line starting with a semicolon (;) is interpreted as a (non-executable) comment line.
 "Unnecessary" parameters (e.g. list mode parameters for generators which do not support list
mode) are ignored and cause a warning, if logging is activated.
 In case of configuration file errors, the external device is marked with the symbol in the System
Configuration dialog, and the external device is not available for use.
The following conditions are checked and treated as errors:
— Multiple occurrence of a configuration file entry
— Presence of any additional, unsupported entry
— Missing "mandatory" parameters. Some of the "mandatory" parameters are not utilized by the
network analyzer although they must be included in the configuration files.
 Optional parameters:
A missing "optional" parameter is identical to an entry with empty string; i.e. the following 2 lines
are equivalent:
; GENERATORREFEXT
GENERATORREFEXT =
 SCPI command sequence:
It is possible combine several SCPI-commands, separated by semicolons, into one command line.
Example:
GENERATORINIT = *RST;*CLS;*PSC 1;*ESE 0;*SRE 16;:LEVEL:RF ON
 It is not allowed to use *OPC and *OPC? in a command sequence (creates an error message in
case of activated error logging).
