[:SOURce<hw>]:SWEep[:FREQuency]:POINts
<Points>
Determines the number of steps for the RF frequency sweep within the sweep range.
This parameter always applies to the currently set sweep spacing and correlates with
the step size as follows:
●
for linear sweeps
freq_points = (f
SPAN
/ step_lin) + 1
To determine the step size, use the command
.
●
logarithmic sweeps and f
STARt
< f
STOP
freqq_points = ((log f
STOP
- log f
STARt
) / log step_log) + 1
To determine the logarithmic step size, use the command
.
If you change the number of sweep points, the step size changes accordingly. The
sweep range remains the same.
Parameters:
<Points>
integer
Range:
2..max
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<hw>]:SWEep[:FREQuency]:RETRace
<State>
Activates that the signal changes to the start frequency value while it is waiting for the
next trigger event.
You can enable this feature, when you are working with sawtooth shapes in sweep
mode "Single" or "External Single".
Parameters:
<State>
0 | 1 | OFF | ON
*RST:
0
Example:
TRIG0:SWE:SOUR SING
FREQ:MODE SWE
SWE:SHAP SAWT
SWE:RETR ON
activates retrace function, i.e. the frequency changes to the
value at start frequency while waiting for the next trigger event.
