Slope ← TRIG A, TRIG B
Slope to be used for output trigger signals. The trigger event can either be marked by a
rising edge or by a falling edge.
Remote command:
TRIGger:BASE:EXTB:SLOPe etc.
User Initiated Trigger
A user initiated trigger signal is useful if several applications shall be triggered simulta-
neously and the absolute trigger timing is irrelevant.
You can for example start waveform files (ARB files) in several GPRF generators simul-
taneously to generate a MIMO signal. To do so, select one of the user initiated triggers
as trigger source in the relevant GPRF generator instances and initiate the trigger event
by pressing the "Start" button.
Related trigger source strings: "Base1: User Trigger 1" and "Base1: User Trigger 2"
Remote command:
TRIGger:BASE:UINitiated<n>:EXECute
4.4.8 Logging
If supported by a signaling application, messages exchanged between the signaling
application and the DUT can be monitored.
For this purpose an external logging PC is connected to the LAN SWITCH connector
provided by the "Ethernet Switch H661A" (option R&S CMW-B661A). The messages are
sent to the logging PC, where the R&S Message Recorder (option R&S CMW-KT011) is
installed. It generates log files of the messages which can then be analyzed using the
R&S Message Analyzer (also option R&S CMW-KT011). For more information please
refer to the documentation delivered with the R&S Message Recorder, e.g. the MCT
Tools Manual.
If your instrument is not equipped with a data application unit (option R&S CMW-B450A),
message monitoring requires a specific IP address assigned to the "Lan Remote" network
adapter; see chapter 4.4.9, "IP Subnet Configuration", on page 101.
The "Logging" section of the "Setup" dialog provides general settings, applicable to all
signaling applications supporting message monitoring.
