Parameters:
<Mode> AUTO | MANual | STEP
AUTO
Each trigger triggers exactly one complete sweep.
MANual
The trigger system is not active. Each frequency step of the sweep
is triggered individually, either by varying the "Current Fre-
quency" value using the rotary knob under manual control or by
means of a FREQ:MAN command under remote control. With man-
ual control, the frequency increases or decreases (depending on
the direction of the rotary encoder) by the value specified under
FREQ:STEP:INCRement. With remote control, the frequency is
set directly with the command :FREQ:MAN.
STEP
Each trigger triggers one sweep step only (Mode Single Step). The
frequency increases by the value entered under
SOUR:SWE:FREQ:STEP:LIN (linear spacing)
or ...:STEP:LOG (logarithmic spacing).
*RST:
AUTO
Example:
SWE:MODE AUTO
selects Mode Auto for a frequency sweep at the RF output.
Manual operation: See "Mode - Frequency Sweep" on page 149
[:SOURce<hw>]:SWEep[:FREQuency]:OVOLtage:STARt <Start>
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:
<Start> float
Range: -3 to 3
Increment: 1E-3
*RST: 0
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 Start Freq - RF Frequency Sweep"
