[:SOURce]:SWEep:[:FREQuency]:RUNNing?
The c
ommand set a queries whether a sweep is being performed.
Example: SOUR:SWE:FREQ:RUNN?
Note: This query may cause distortions in the course of the sweep, depending on the frequency
of checkimng and dwell time.
[:SOURce]:SWEep[:FREQuency]:SPACing LINear | LOGarithmic
The command selects whether the steps have linear or logarithmic spacings.
Example: :SOUR:SWE:SPAC LIN *RST value is LIN
[:SOURce]:SWEep[:FREQuency]:STEP[:LINear] 0 to 1 GHz/0 to 2 GHz /0 to 3 GHz (R&S SML)
The command sets the step width with the linear sweep. A change of SPAN does not result in a
change of
:STEP[:LIN]
. Keyword
[:LIN]
can be omitted, then the command conforms to
SCPI regulations (see example).
Example: :SOUR:SWE:STEP 1MHz *RST value is 1 MHz
[:SOURce]:SWEep[:FREQuency]:STEP:LOGarithmic 0.01 to 100 PCT
The command indicates the step width factor for logarithmic sweeps. The next frequency value of
a sweep is calculated according to
new frequency = previous frequency + STEP:LOG x previous frequency (if STARt < STOP)
:STEP:LOG
indicates the fraction of the previous frequency by which this is increased for the next
sweep step. Usually :STEP:LOG is indicated in percent. A change of STARt or STOP does not
result in a change of :STEP:LOG.
Example: :SOUR:SWE:STEP:LOG 10PCT *RST value is 1 PCT
[:SOURce]:SWEep:POWer:DWELl 10 ms to 5 s
The command sets the dwell time per level step.
Example: :SOUR:SWE:POW:DWEL 12ms *RST value is 15 ms
[:SOURce]:SWEep:POWer:MODE AUTO | MANual | STEP
The command specifies the sweep mode.
AUTO Each trigger triggers exactly one entire sweep cycle.
MANual Each level step of the sweep is triggered by means of manual control or a
SOUR:POW:MAN command, the trigger system is not active. The level increases or
decreases (depending on the direction of the shaft encoder) by the value stated
under [:SOUR]:POW:STEP:INCR.
STEP Each trigger triggers only one sweep step (single-step mode). The level increases by
the value indicated under
[:SOUR]:POW:STEP:INCR
.
Example: :SOUR:SWE:POW:MODE AUTO *RST value is AUTO
