[:SOURce<hw>]:SWEep[:FREQuency]:OVOLtage:STOP <Stop>
The command 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 154
[: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:
●
for linear sweeps
POINts = (SPAN / STEP:LIN) + 1
●
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.
Parameters:
<Points> float
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.
