Adjusting Limits
The Site Master offers two types of limits: a single horizontal limit line and segmented lim-
its.
Adjusting a Single Limit
Step 1.
Press the
LIMIT
key.
Step 2.
Press the
Single Limit
soft key.
Step 3.
Press the
Edit
soft key.
Step 4.
Either enter the value using the numeric keypad or scroll the limit line using the
Up/Down arrow key.
Step 5.
Press
ENTER
to set the location of the limit line.
NOTE
: The single limit line can be defined as either an upper limit or a lower
limit in Spectrum Analyzer mode only.
Defining an Upper Limit
An upper limit in Spectrum Analyzer mode is one where the measurement fails if the data
appears above the limit line.
Press the
Upper/Lower Limit
soft key, if necessary, so that the status window says:
Fail if data is: Above Line
.
Defining a Lower Limit
A lower limit in Spectrum Analyzer mode is one where the measurement fails if the data
appears below the limit line.
Press the
Upper/Lower Limit
soft key, if necessary, so that the status window says:
Fail if data is: Below Line
.
Adjusting Segmented Limits
Segmented limit lines are defined separately as five upper limit segments and five lower
limit segments. This allows the definition of a spectral mask.
A limit segment is defined by its end points. That is, starting frequency, starting amplitude,
ending frequency, and ending amplitude. This procedure describes the setting of two upper
limit segments. The steps can be carried over to the other upper limit segments as well as to
the lower limit segments.
Step 1.
Press the
LIMIT
key.
Step 2.
Press the
Multiple Upper Limits
soft key.
Step 3.
Press the
Segment 1
soft key.
Step 4.
Press the
Edit
soft key. The status window will successively display the value of
the segment endpoints:
Start Freq, Start Limit, End Freq, End Limit
.
Step 5.
Edit each value using the numeric keypad or scroll the limit line using the
Up/Down arrow key and press
ENTER
to set.
