Measuring Multiple Signals
Easily Measure Varying Levels of Modulated Power Compared to a Reference
11 Enable the Delta Band
Power Marker
functionality.
• Press Marker, Select Marker,
Marker 1, Delta.
This will change the reference
Band Power Marker into a fixed
power value (labeled X2) and
initiate a second Band Power
Marker (labeled 1 Δ 2) to
measure any changes in power
levels relative to the reference
Band Power Marker X2.
12Simulate a varying power
level resulting from either
adjustments, changes to
the reference DUT, or a
different DUT by
lowering the signal source
power.
• Set the source amplitude to
–20 dBm.
Note the Delta Band Power
Marker value displayed in the
Marker Result Block showing
the 10 dB difference between
the modulated power of the
reference and the changed
power level.
