Description
The check mark indicator denotes the display for which the acquisition
hardware is optimized. This indictor appears only when the display is the
selected display.
Appears when averaging is enabled (Settings > Parameters tab > Average
results). Displays "Avg: n of m" while averaging the results and "Avg: m"
once the requested number of results have been averaged.
Adjusts the vertical and horizontal settings so that the entire trace fits in the
graph.
Displays either Normal or MaxHold to indicate trace function.
Resets count for Average and MaxHold functions. Enabled only when
Averaging or MaxHold is enabled. Pressing Clear will clear the trace and, if
acquisition is running, restart the averaging or hold process.
Displays the input signal. Shaded areas indicate the measurement bandwidth
(Settings > Parameters tab > Measurement BW).
The blue lines indicate where the selected results (selected in the Main
results area) are being measured on the trace.
Determines the portion of the display allocated to the graph and detailed
results area. You can move the grid divider all the way to the top or bottom
and any position in between.
Displays additional measurements results.
Position sets the top of graph value. The dB/div setting is the vertical scale
value.
Displays results for Occupied Bandwidth (OBW) and x dB bandwidth. Use
the two radio buttons to select which of the two results are illustrated in the
graph with the blue lines and arrows. There are also controls for adjusting
OBW % Power, x dB BW, and RBW.
Enables the VBW (Video Bandwidth) filter. Displays current VBW filter setting.
See Setup > Settings >
Description
The frequency difference between the measured carrier frequency of the signal and the
user-selected center frequency of the analyzer.
The signal level at the left edge of the occupied bandwidth.
The signal level at the right edge of the occupied bandwidth.
The total power measured within the measurement bandwidth.
The peak power measured within the measurement bandwidth.
