[:SOURce<hw>]:SWEep[:FREQuency]:POINts <Points>
The command sets the number of steps in an RF sweep. The command is linked to the
command :SWEep[:FREQuency]:STEP as follows:
The following applies for linear sweeps:
POINts = (SPAN / STEP:LIN) + 1
The following applies for logarithmic sweeps and STARt < STOP:
POINts = ((log STOP - log STARt) / log STEP:LOG) + 1
If POINTs changes, the value of STEP is adjusted. The STARt and STOP value is retained.
Two separate POINts values are used for linear or logarithmic sweep spacing
(:SWEep[:FREQuency]:SPACing LIN | LOG). The command is always effective for
the currently set sweep spacing.
Correlation: The value of :SWE:STEP is adjusted automatically.
Parameters:
float<Points>
FREQ:STAR
sets the start frequency to 100 MHz.
FREQ:STOP
sets the stop frequency to 500 MHz.
SWE:SPAC LIN
sets linear sweep spacing.
SWE:POIN 401
sets 401 sweep steps for linear sweep spacing. The sweep step
width (STEP) is automatically set to 1 MHz.

[:SOURce<hw>]:SWEep[:FREQuency]:SHAPe <Shape>
The command sets the cycle mode for a sweep sequence (shape).
Parameters:
SAWTooth|TRIangle
SAWTooth
One sweep runs from start to stop frequency. Each subsequent
sweep starts at the start frequency, i.e. the shape of the sweep
sequence resembles a sawtooth.
TRIangle
One sweep runs from start to stop frequency and back, i.e. the
shape of the sweep resembles a triangle. Each subsequent sweep
starts at the start frequency.
