SME SOURce:SWEep
1038.6002.02 3.105 E-13
[: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 run of the sweep.
AUTOEach trigger triggers exactly one entire sweep cycle.
MANual Each level step of the sweep is triggered by means of manual control or a
SOURce:POWer:MANual 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 :SOURce:POWer:STEP: INCRement.
STEP Each trigger triggers only one sweep step (single-step mode). The level increases by
the value indicated under :SOURce:POWer:STEP: INCRement.
Example: :SOUR:SWE:POW:MODE AUTO *RST value is AUTO
[:SOURce]:SWEep:POWer:POINts Number
The command determines the number of steps in a sweep. Instead of this command, command
SOURce:SWEep:POWer:STEP:LOGarithmic should be used, as POINts has been adapted to the
instrument characteristics in comparison to the SCPI command.
The value of :POINts depends on .SPAN and :STEP according to the following formulas:
POINts = ((log STOP - log STARt) / log STEP:LOG) + 1
A change of POINts results in an adaptation of STEP but not of STARt, STOP and SPAN.
Example: :SOUR:SWE:POW:POIN 100
[:SOURce]:SWEep:POWer:STEP:LOGarithmic 0 to 10 dB
The command indicates the step width factor for logarithmic sweeps. The next level value of a
sweep is calculated according to
new level = prior level + STEP:LOG × prior level
STEP:LOG indicates the fraction of the prior level by which this is increased for the next sweep
step. Usually STEP:LOG is indicated in dB, with suffix dB having to be used explicitly. If
STEP:LOG is changed, the value of POINts also changes according to the formula indicated
under POINts. A change of STARt or STOP does not result in a change of STEP:LOG. Keyword
:LOG can be omitted, then the command conforms to SCPI regulation (see example).
Example: :SOUR:SWE:STEP 10dB *RST value is 1dB
