Coupled Sweep Commands - Keithley 6220 Reference Manual

4-22 Sweeps
4. SOUR:LIST:CURR:POIN?
SOUR:LIST:DEL:POIN?
SOUR:LIST:COMP:POIN?
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
CENTer = CENTer
STOP
STARt
SWEep:POINts= SWEep:POINts
STEP
When STARt or STOP changes:
STARt
STOP
CENTer = (STARt + STOP)/2
SPAN
SWEep:POINts= SWEep:POINts
STEP
When SWEep:POINts changes:
STARt
STOP
CENTer = CENTer
SPAN
STEP
When STEP changes:
STARt
STOP
CENTer = CENTer
SPAN
SWEep:POINts= SPAN / STEP + 1
When spacing is set to LOG:
POINts/DECADE = (SWEep:POINts - 1)/SPAN (in decades)
