[:SOURce<hw>]:SWEep[:FREQuency]:OVOLtage:STOP <Stop>
Sets the voltage at the sweep stop frequency. The linear voltage ramp from sweep
start to stop is output at the LF connector.
Parameters:
<Stop> float
Range:
-3 to 3
Increment: 1E-3
*RST:
3
Example: SWE:LFC ON
activates the output of a linear voltage ramp from sweep start to
sweep stop at the LF connector.
SWE:OVOL:STAR 0V
SWE:OVOL:STOP 3V
the voltage at the sweep start frequency is 0 V and at the stop
frequency 3 V.
Manual operation: See "Output Voltage Stop - RF Frequency Sweep" on page 182
[: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 SWE:STEP[:LIN] .
●
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 SWE:STEP:LOG .
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.
