R&S SMC100A Command Description
1411.4060.32 6.77 E-1
[SOURce:]SWEep[:FREQuency]:POINts <numeric_value>
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.
Example:
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:]SWEep[:FREQuency]:SHAPe SAWTooth | TRIangle
The command sets the cycle mode for a sweep sequence (shape).
Parameters: 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.
Example:
SOUR:SWE:SHAP TRI
'selects the sweep cycle with alternating sweep directions.
