Modifier name: LIMIT
Modifier Syntax 1: LIMIT hs state
state definition: ON, OFF
turns off entire limit line for the specified channel.
Modifier Syntax 2: LIMIT hs numerical value or ALL modifier
valid numerical values: 1 to 12 corresponding to segment numbers
Limit Modifier 1: CLEAR
clears segment n (or all) for active channel’s limit lines
Modifier Syntax: CLEAR
Limit Modifier 2: POINT
defines a point limit
Modifier Syntax: POINT hs f1 ds p1 ds p2
Argument syntax: see Limit Modifier 4, below
Limit Modifier 3: FLAT
defines a flat line segment limit
Modifier Syntax: FLAT hs f1 ds p ds p2 ds f2
Argument syntax: see Limit Modifier 4, below
Limit Modifier 4: SLOPE
defines a sloping line segment limit
Modifier Syntax: SLOPE hs f1 ds p1 ds p2 ds f2 ds p3 ds p4
Argument syntax: f1 starting frequency in MHz
p1 upper limit in dB (starting limit)
p2 lower limit in dB (starting limit)
f2 ending frequency in MHz
p3 ending upper limit in dB
p4 ending lower limit in dB
Modifier Examples: SWP 1;LIMIT 1;POINT 2500,10.5,9.5
Defines a point limit line for channel 1 at 2500 MHz with
10.5 dB upper limit, and 9.5 dB lower limit
SWP 1;LIMIT ON
Turns on limit line defined above.
SWP 3;LIMIT 3;SLOPE 8000,0,-5,12000,5,-10
Defines a slope limit segment (third segment of the limit
line) for channel 3. Line is defined from 8 GHz to 12
GHz. Upper segment goes from 0 dB at 8 GHz to 5 dB
at 12 GHz. Lower segment goes from -5 to -10 dB.
SWP 3;LIMIT 3;CLEAR
Clears third segment of limit line on channel 3.
