4-22 Sweeps Model 6220/6221 Reference Manual
Return to Section 4 topics
4. SOUR:LIST:CURR:POIN? ‘ Query current list length
SOUR:LIST:DEL:POIN? ‘ Query delay list length
SOUR:LIST:COMP:POIN? ‘ Query compliance list
These commands query the length of the current source, delay, and compli-
ance lists. The number of current values determines the length of the list
sweep; the other two POINts? queries are for reference only.
Coupled sweep commands
A number of sweep commands are coupled together, and changing certain
parameters also changes others. The following is a list of coupled commands.
When SPAN or CENTer changes:
SPAN = SPAN
CENTer = CENTer
STOP = CENTer + (SPAN/2)
STARt = CENTer - (SPAN/2)
SWEep:POINts= SWEep:POINts
STEP = SPAN / (SWEep:POINts -1)
When STARt or STOP changes:
STARt = STARt
STOP = STOP
CENTer = (STARt + STOP)/2
SPAN = STOP - STARt
SWEep:POINts= SWEep:POINts
STEP = SPAN / (SWEep:POINts -1)
When SWEep:POINts changes:
STARt = STARt
STOP = STOP
CENTer = CENTer
SPAN = SPAN
STEP = SPAN / (SWEep:POINts -1)
When STEP changes:
STARt = STARt
STOP = STOP
CENTer = CENTer
SPAN = SPAN
SWEep:POINts= SPAN / STEP + 1
When spacing is set to LOG:
POINts/DECADE = (SWEep:POINts - 1)/SPAN (in decades)
