POW:STEP:MAX? 

Description: 

Get the maximum step size of the carrier amplitude step size. 

Syntax: 

[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]:STEP:MAXimum? 

Example: 

Write: 

POW:STEP:MAX?

  

Response: 

:POW:STEP:MAX 100.00

 

 

POW:STEP:MIN? 

Description: 

Get the minimum step size of the carrier amplitude step size 

Syntax: 

[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude]:STEP:MINimum? 

Example: 

Write: 

POW:STEP:MIN?

  

Response: 

:POW:STEP:MIN 0.01

 

 

PULM:BURST:NUM 

Description: 

Set the number of pulses in a period for the pulse burst modulation (pulse 
gating). The value can be set between 1 

– 1000. 

 

Note that the maximum number is depending on the period time, pulse width and 
delay, as the number of pulses will need to fit in the selected burst period time 

Syntax: 

[:SOURce]:PULM:BURST:NUMber <pulse number> 

Example: 

Write: 

PULM:BURST:NUM 50

 

 

PULM:BURST:NUM? 

Description: 

Gets the number of pulses in a period for the pulse burst modulation  (pulse 
gating). 

Syntax: 

[:SOURce]:PULM:BURST:NUMber? 

Example: 

Write: 

PULM:BURST:NUM? 

Response: 

:PULM:BURST:NUM 50
