transmitted. #0 specifies a data block of indefinite length. The use of the indefinite for-
mat requires an NL^END message to terminate the data block. This format is useful
when the length of the transmission is not known or if speed or other considerations
prevent segmentation of the data into blocks of definite length.
8.2 Common Suffixes
In the I/Q Analyzer, the following common suffixes are used in remote commands:
Table 8-1: Common suffixes used in remote commands in the I/Q Analyzer
Suffix Value range Description
<m> 1 to 16 Marker
(or spot noise marker)
<n> 1 to 6 Window (in the currently selected channel)
<t> 1 to 6 Trace
<li> 1 to 8 Limit line
<j> 1..10 Selects an integrated measurement range.
<k> 1..8 (Limit line)
1 | 2 (Display line)
Selects a limit or display line.
<r> 1..x Selects a half decade.
The value range depends on the number of half decades. The first
half decade in the measurement always has the value "1". For sub-
sequent half decades, add "1" to get the value "x" (the fourth half
decade, for example, would have the value "4").
<s> 1..6 Selects a (user defined) spot noise marker.
<x> 1..2 Selects a mixer in the test setup.
Selecting windows in multiple channels
Note that the suffix <n> always refers to a window in the currently selected channel.
8.3 Activating I/Q Analyzer Measurements
I/Q Analyzer measurements require a special measurement channel on the
R&S FSWP. It can be activated using the common INSTrument:CREate[:NEW] or
INSTrument:CREate:REPLace commands. In this case, some - but not all - param-
eters from the previously selected application are passed on to the I/Q Analyzer chan-
nel. In order to retain all relevant parameters from the current application for the I/Q
measurement, use the TRACe:IQ[:STATe] command to change the application of
the current channel.
