3 Spectrum Analyzer Mode
3.2 Swept SA Measurement
Notes:
–
Trigger sync connections are optional – synchronization can be done via remote
commands if Bus Trigger is enabled in the Source Setup menu.
–
Connection from the SA external frequency reference output to the source
frequency reference input (10 MHz Out to Ref In) is not required, but may
improve the measurement accuracy.
SW Trigger
Analyzer and source point trigger synchronization is setup using the SCPI
commands. Source is stepped via SCPI commands. Analyzer waits for source to
settle by polling source.
SCPI example: :SOUR:TRIG:TYPE BUS
Ext Trigger 1
SCPI example: :SOUR:TRIG:TYPE EXT1
Analyzer and source point trigger synchronization is setup using the analyzer Trigger
1 Output and Trigger 1 Input. The Source is stepped via Trigger 1 Output. The
Analyzer waits for source to settle via Trigger 1 Input.
With an acquired source, selecting this point trigger mode overrides existing
external trigger 1 output level, slope, and delay, and external trigger 1 type and
polarity.
External trigger 1 input level = 1.20 V
External trigger 1 input slope = Positive
