10 Spectrum Emission Mask Measurement
Sweep/Control
Reset Offset Display
Resets the value of the periodic trigger offset display setting to 0.0 seconds. The current displayed trigger
location may include an offset value defined with the Offset key. Pressing this key redefines the currently
displayed trigger location as the new trigger point that is 0.0 s offset. The Offset key can then be used to
add offset relative to this new timing.
Key Path
Trigger, Periodic Timer
Remote Command
:TRIGger[:SEQuence]:FRAMe:OFFSet:DISPlay:RESet
Example
TRIG:FRAM:OFFS:DISP:RES
Initial S/W Revision
Prior to A.02.00
Sync Source
Selects a signal source for you to synchronize your periodic timer trigger to, otherwise you are triggering at
some arbitrary location in the frame. Synchronization reduces the precision requirements on the setting of
the period.
For convenience you may adjust the level and slope of the selected sync source in a conditional branch
setup menu accessed from the Sync Source menu. Note that these settings match those in the Trigger and
Gate Source menus; that is, each trigger source has only one value of level and slope, regardless of which
menu it is accessed from.
Key Path
Trigger, Periodic Timer
Remote Command
:TRIGger[:SEQuence]:FRAMe:SYNC EXTernal1 | EXTernal2 | RFBurst | OFF
:TRIGger[:SEQuence]:FRAMe:SYNC?
Example
TRIG:FRAM:SYNC EXT2
Dependencies
In some models, there is no second External input. In these models, the External 2 key is blanked and
the EXTernal2 parameter will generate a “Hardware missing; Not available for this model number”
message.
Preset
Off
GSM/EDGE, MSR,LTE,LTETDD: RFBurst
State Saved
Saved in instrument state
Readback
The current setting is read back to this key and it is also Readback to the previous Periodic Timer
trigger key.
Backwards
Compatibility SCPI
:TRIGger[:SEQuence]:FRAMe:SYNC EXTernal
For backward compatibility, the parameter EXTernal is mapped to EXTernal1
