Offset Adjust (Remote Command Only)This remote command does not work at all like the related front panel keys. This command lets you advance the phase of the frame trigger by the amount you specify.It does not change the period of the trigger waveform. If the command is sent multiple times, it advances the phase of the frame trigger an additional amount each time it is sent. Negative numbers are permitted.
Notes: The front panel interface (for example, the knob), and this command, adjust
the accumulated offset, which is shown on the active function display.
However, the actual amount sent to the hardware each time the offset is
updated is the delta value, that is, the current accumulated offset value minus
the previous accumulated offset value. Note that the accumulated offset value
is essentially arbitrary; it represents the accumulated offset from the last time
the offset was zeroed (with the Reset Offset Display key).
Note that this command does not change the period of the trigger waveform.
Note also that Offset is used only when the sync source is set to OFF,
otherwise delay is used, see section “Trig Delay” on page 1372.
An increase in the "offset" parameter, either from the knob or the SCPI adjust
command, serves to delay the timing of the trigger event.
Notes: When the SCPI command is sent the value shown on the key (and the Active
Function, if this happens to be the active function) is updated with the new
value. However, the actual amount sent to the hardware is the delta value, that
is, the current accumulated offset value minus the previous accumulated offset
value.
The SCPI query simply returns the value currently showing on the key.
Dependencies: The invalid data indicator turns on when the offset is changed, until the next
sweep/measurement completes.
Couplings: The same offset is used in the Gate Source selection of the period timer.
