signal. This scale is suitable for observing rise and fall behavior of AM or pulse-modulated signals such
as radar and TDMA transmitters.
2.2.1.5
Filter
Set the RBW filter type. The analyzer
supports two kinds of RBW filters: “
Gauss
” (-3 dB bandwidth) and
“
EMI
” (-6 dB bandwidth).
When “
EMI
” is selected, resolution bandwidth can only be 200 Hz, 9 kHz, 120 kHz and 1 MHz
“
Quasi-Peak
” detector is available only when “
EMI
” filter is turned on.
2.2.2 Trace
The sweep signal is displayed as a trace on the screen.
2.2.2.1
Select Trace
The analyzer allows for up to four traces to be displayed at the same time. Each trace has its own color
(Trace A - Yellow, Trace B - Purple, Trace C - Light blue and Trace D - Green). All traces can be set
parameter independently. As a default, analyzer will choose Trace A and set the type of the trace as
Clear Write.
2.2.2.2
Trace Type
Set the type of the current trace or disable it. The system calculates the sampled data using a specific
operation method according to the trace type selected and displays the result. Trace types include
Clear Write, Max Hold, Min Hold, View, Average and Blank. The corresponding icon of the trace type
will be displayed in the status bar at the left of the screen, as shown in the figure below.
