The Magnitude Capture Buffer display shows the complete range of captured data for
the last sweep. All analyzed bursts are identified with a green bar at the bottom of the
Magnitude Capture Buffer display. If, in the "Demod Settings" dialog box, the "Signal
Field Content" option is activated, only bursts that match the required criteria are
marked with a green bar (see "Signal Field Content (IEEE 802.11a, g (OFDM), j & n
(SISO), p)" on page 98).

●
I/Q measurements
All I/Q measurements process the same signal data and as such all I/Q measure-
ment results are available after a single I/Q measurement execution.
I/Q measurements can be run in split screen mode (allowing both the Magnitude
Capture Buffer display and the selected I/Q measurement results to be displayed
simultaneously) or in full screen mode (with either the Magnitude Capture Buffer
display or the selected I/Q measurement results displayed).
●
Frequency sweep measurements
The frequency sweep measurements use different signal data to I/Q measure-
ments and as such it is not possible to run an I/Q measurement and then view the
results in the frequency sweep measurements and vice-versa. Also because each
of the frequency sweep measurements uses different settings to obtain signal data
it is not possible to run a frequency sweep measurement and view the results of
another frequency sweep measurement.
All frequency sweep measurements are run in full screen mode.
