3.1.3.1 CALCulate:LIMit Subsystem
The CALCulate:LIMit subsystem consists of the limit lines and the corresponding limit
checks. The limit lines can be defined as upper or lower limit lines. The individual Y
values of the limit lines correspond to the values of the X-axis (CONTrol). The number
of X- and Y-values must be identical.
Up to 6 limit lines can be defined at the same time (marked by LIMIT1 to LIMIT6) in the
screen.
Each limit line can be assigned a name. An explanatory comment can also be given for
each.
Example
Definition and use of a new limit line 5 for trace in the Noise Figure trace screen with
the following features:
•
upper limit line
•
5 ref. values: 126 MHz/-40 dB, 127 MHz/-40 dB, 128 MHz/-20 dB, 129 MHz/-40 dB,
130 MHz/-40 dB
Definition of the line:
Defining the name:
CALC:LIM5:NAME 'TEST1'
Entering the comment:
CALC:LIM5:COMM 'Upper limit line'
Associated trace in screen A:
CALC:LIM5:TRAC NFIG
Defining the X-axis values:
CALC:LIM5:CONT 126MHZ, 127MHZ, 128MHZ,
129 MHZ, 130MHZ
Defining the y values:
CALC:LIM5:UPP -40, -40, -30, -40, -40
The definition of the safety margin and shifting in X- and/or Y-direction can take place
as from here (see commands below).
