M
a delta marker, effectively allowing up to 12 markers on screen. The user may
lso set marker 1 to be the reference for 6 delta markers.
a
Marker Table: Display a table of up to six marker frequency and amplitude
values plus delta marker frequency offset and amplitude.
Upper/Lower Limit
Fixed and segmented: Each upper and lower limit can be made up of
between one and 40 segments.
Smart Measurements
ccupied Bandwidth:Measures 99% to 1% power channel of a signal.
