GPIB Command Conventions

SYSTem:CORRection:[:SGAin]

Function

Sets/queries up to 20 comma-separated amplitude offset values in dB. This command sets the state to On.

See Amplitude Offset .

The units, dB, are optional. If no units are specified then units default to dB.

Sending a null list (no values) sets the state of all offsets to Off.

Setting

Range: 0 to 20 values between -100 to +100

Resolution: 0.01

Query

Range: 1 to 20 values between -100 to +100, and NAN (9.91E+37)

Resolution: 0.01

Factory Setting

Offsets 1 through 20, are set to 0.00 dB, state is set to Off

Programming Example

 
OUTPUT 714;"SYSTEM:CORRECTION:SGAIN -2.55,-3.12,-3.68,-4.23,-4.74,-5.3"

!Sets the state for all frequencies and offsets to Off

SYSTem:CORRection:FREQuency

Function

Sets/queries up to 20 comma-separated frequency values in MHz. Each frequency value corresponds with a gain setting. See SYSTem:CORRection:GAIN .

Programming Example

 
OUTPUT 714;"SYSTEM:CORRECTION:SFREQUENCY 1710.2 MHZ,1805.2 MHZ,1784.8 MHZ,1879.8 MHZ"
!Sets up to 20 comma separated frequencies and sets the state to On for the frequency,
!offset, and RF IN/OUT Amplitude Offset State
 
OUTPUT 714;"SYSTEM:CORRECTION:SFREQUENCY"
!Sets the state for all frequencies and offsets to Off

SYSTem:CORRection:STATe

Function

Sets/queries the RF IN/OUT Amplitude Offset State. The state must be On before any of the offsets are active regardless of the state for any of the frequencies or offsets.

When the RF IN/OUT Amplitude Offset State is On, the Instrument Status Area will indicate "Offset" regardless of the state for any of the frequencies or offsets.

Setting any of the frequency or offset states to On will set the RF IN/OUT Amplitude Offset State to On.

See Amplitude Offset .

Setting

0|OFF | 1|ON

Query

0|1

Factory Setting

0 (off)

Programming Example

 
OUTPUT 714;"SYSTEM:CORRECTION:STATE ON" !Sets the RF IN/OUT
                                        !Amplitude Offset State to On
