The :SENSe{1-16}:OFFSet and :SENSe{1-16}:OFFSet{1-50} subsystem commands are used to configure the frequency offsets for external sources, internal receivers, and related functions for the currently active device or function. Use the :OFFSet{1-50} commands to configure the frequency offsets for external sources, internal receivers, and related functions for the indicated offset number.
Trigger, Hold, and External Source Subsystems
Related trigger, hold, and external source subsystems are:
As a general rule, it is best to first set the offset state to Define mode. To do this, issue the command:
:SENS1:OFFS DEF
Update all Multiple Source bands as needed, then issue the Done command:
:SENS1:OFFS:DON
:SENSe{1-16}:OFFset Commands
Use the :SENSe{1-16}:OFFSet commands to create and setup multiple source bands. The relative sequence is:
• Configure Band 1
• When started, Band 1 exists with a starting frequency of the lowest instrument frequency, and a top ending frequency of the highest instrument frequency.
• Change the Band 1 top frequency to something lower than the instrument maximum frequency.
• Accept the band defaults of receiver source = ON, source state = ON, and delay state = OFF, or configure as required.
• Create and Configure Band 2
• Create a new band which automatically becomes Band 2 with a starting frequency 1 Hz higher than the end frequency of Band 1 and an end frequency of the highest instrument frequency.
• If another band is required, configure the end frequency at least 3 Hz lower than the instrument maximum frequency.
• Accept the band defaults of receiver source = ON, source state = ON, and delay state = OFF or configure as required.
• Create and Configure Band N
• Create a new band which automatically becomes the next higher Band with a starting frequency 1 Hz higher than the end frequency of the prior Band and an end frequency of the highest instrument frequency.
• If another band is required, configure the end frequency at least 3 Hz lower than the instrument maximum frequency.
• If this is the last band, and a lower end frequency is required, configure the band end frequency.
• Accept the band defaults of receiver source = ON, source state = ON, and delay state = OFF or configure as required.
:SENSe{1-16}:OFFset{1-50} Commands
Use the :SENSe{1-16}:OFFSet{1-50} commands to create and setup multiple source bands. These indexed :OFFSet commands allow a specified existing band to be configured. The relative command sequence is:
• Modify and configure the default existing Band 1 using :OFFSet{1} commands.
• When started, Band 1 exists with a starting frequency of the lowest instrument frequency, and a top ending frequency of the highest instrument frequency.
• Change the Band 1 top frequency to something lower than the instrument maximum frequency.
• Accept the band defaults of receiver source = ON, source state = ON, and delay state = OFF or configure as required.
• Create and Configure Band 2
• Create a new band using :OFFSet{2} which becomes Band 2 with a starting frequency 1 Hz higher than the end frequency of Band 1 and an end frequency of the highest instrument frequency.
• If another band is required, configure the end frequency at least 3 Hz lower than the instrument maximum frequency.
• Accept the band defaults of receiver source = ON, source state = ON, and delay state = OFF or configure as required.
• Create and Configure Band N
• Create a new band using the :OFFSet{N} (where N is less than or equal to 50) which automatically becomes the next higher Band with a starting frequency 1 Hz higher than the end frequency of the prior Band and an end frequency of the highest instrument frequency.
• If another band is required, configure the end frequency at least 3 Hz lower than the instrument maximum frequency.
• If this is the last band, and a lower end frequency is required, configure the band end frequency.
• Accept the band defaults of receiver source = ON, source state = ON, and delay state = OFF or configure as required.
