Keysight x-series User Manual

4 System
4.6 Alignments
The USER setting sets the Timebase DAC to the value set on the User Value control.
In this case the value displayed at the top of the screen is the user value.
Remote Command
:CALibration:FREQuency:REFerence:MODE CALibrated | USER
:CALibration:FREQuency:REFerence:MODE?
Example
:CAL:FREQ:REF:MODE CAL
Notes If the value of the timebase is changed the alignment system automatically performs an alignment or
alerts that an alignment is due
Dependencies Not available in UXM
Preset Unaffected by Preset, but set to CALibrated by Restore Defaults >"Alignments" on page 2100
State Saved No
4.6.5.2 User Value
Lets you set the Timebase DAC to a value other than the value established during
the factory or field calibration. The current value of the DAC is displayed at the top
of the screen. This will be the Calibrated value if Timebase DAC is set to
CALibrated.
Remote
Command
:CALibration:FREQuency:REFerence:FINE <integer>
:CALibration:FREQuency:REFerence:FINE?
Example
:CAL:FREQ:REF:FINE 8191
Notes If the value of the timebase is changed the alignment system automatically performs an alignment or
alerts that an alignment is due
Couplings Setting :CAL:FREQ:REF:FINE sets :CAL:FREQ:REF:MODE USER

SCPI
:CALibration:FREQuency:REFerence:COARse
ESA hardware contained two DAC controls for the Timebase. In X-Series the command :CALibra-
tion:FREQuency:REFerence:FINE is the method for adjusting the timebase. The COARse
option is provided as an alias to FINE

:CALibration:FREQuency:REFerence:COARse?
Example
:CAL:FREQ:REF:COAR 8191
Notes This is an alias for :CAL:FREQ:REF:FINE. Any change to COARse is reflected in FINE and vice-
versa. See :CAL:FREQ:REF:FINE for description of functionality
