FSC:SCAN2:POIN 200 Set Range 2 to have 200 points.

FSC:SCAN3:POIN:AUTO 1 ! Turn on Auto Scan Points in range 3.
FSC:SCAN3:POIN:AUTO?
When set to auto, the selected Auto Step Size Rules will be used to calculate the scan points.
Points/ RBW
The Scan point is calculated based on the number of points for each RBW width, the smallest odd
number >= Number of Points*(Stop Frequency-Start Frequency)/RBW will be used as the scan
points.
Log % of Freq
The Step Size is calculated based on the Log % of Freq of the current frequency. The Scan Points will
be calculated based on the step size.
This key is grayed out when the Step Control is set to "Step Size & Dwell Time". If the grayed out key
is pressed, an advisory message is generated. If the equivalent SCPI command is sent, this same
message is generated as part of a "–221, Settings conflict; Function not available while running
multirange scan" warning.
This key is grayed out during multi range scanning. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict; Function not available while running multirange scan" warning.
This key is grayed out during final measurement. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict" warning.
This key is grayed out during a Time Domain Scan. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict; Function not available with time domain scan type" warning.
If you change the step size to a value that causes the total range point to exceed 40001 the range
state of the specific range will be changed to off. An advisory message is generated. If the equivalent
SCPI command is sent, this same message is generated as part of a "–221, Settings conflict"
warning.
The value of Step Size and Scan Points are always coupled.
Auto Scan Points and Auto Step Size are always coupled.
The scan point of Range 6 depends on the maximum frequency, with a maximum of 34001 points.
