3.3 Instrument subsystem command

 

44

 

 

 
 

Parameter:   

<State> Boolean data is as follows: 

 

ON | 1: Attenuation is AUTO,   

OFF | 0: Attenuation is Manual.   

Example: 

:POWer:ATTenuation:AUTO 0 Attenuation Style is Manual.   

Reset status:

[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude] <Ampl>   

Function: 

This command sets the output amplitude level of the signal generator. 

 

Setting format: 

[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude] <value>   

Query format: 

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

Parameter:   

<Ampl> Amplitude level value.   

Range: -135dBm [-135dBm

，

+30dBm]. 

 

Example: 

:POWer 0dBm The output amplitude level is 0 dBm.   

Reset status: 

-115dBm 

 

Key Entry:

Amplitude

】

   

[:SOURce]:POWer[:LEVel][:IMMediate]:OFFSet <PowOffset>   

Function: 

The  command  is  the  actual  output  amplitude  offset  of  the  signal  generator. When  the 

value is non-

zero, an offset indicator ―*‖ is displayed in amplitude display area and the 

displayed  amplitude  value  is  the  actual  amplitude  power  plus  the  amplitude  offset. 

Such  amplitude  offset  does  not  change  the  actual  output  amplitude  of  the  signal 

generator. Only the displayed amplitude value is changed. 

 

Setting format: 

[:SOURce]:POWer[:LEVel][:IMMediate]:OFFSet <value>   

Query format: 

[:SOURce]:POWer[:LEVel][:IMMediate]:OFFSet? 

 

Parameter:   

<PowOffset> Ampl Offset.   

Range: 0dB [-100dB

，

+100dB]. 

 

Example: 

:POWer:OFFS -10dB Ampl Offset is -10 dB.   

Reset status: 

0dB 

 

Key Entry:

】

—>[Basic Config]->[Ampl Offset]   

[:SOURce]:POWer:REFerence <PowRef>   

Function: 

Ampl  Ref  can  be  set  when  Ampl  Ref  Switch  is  turned  on.  For  the  state  of  power 

reference  switch,  see  the  command  ―

:POWer:REFerence:STATe

‖.  When  Ampl  Ref 

Switch  is  turned  on,  an  indicator  ―*‖  is  displayed  in  amplitude  display  area  and  the 

displayed amplitude value = actual output amplitude - amplitude reference value.   

For example: When current CW output power is 1dBm, if the power reference is set to 

1dBm, the displayed CW output power is based on this power reference. Therefore, 

the  power  display  area  shows  0dBm,  and  the  actual  output  frequency  of  the  signal
