MEAS/DISP Pressing MEAS/DISP in Transmission Measurement mode activates a menu of
bandwidth- and sweep-related functions. Use the corresponding soft key to se-
lect the desired function.
q
Bandwidth
— Activates a menu that allows the resolution and video
bandwidths to be either coupled automatically to the span (Auto) or manually
adjustable (Manual).
q
RBW Auto
— Sets the resolution bandwidth so that it is automatically cou-
pled to the span.
q
RBW Manual
— Sets the resolution bandwidth manually, independent of
the span.
q
VBW Auto
— Sets the video bandwidth so that it is automatically coupled
to the RBW.
q
VBW Manual
— Sets the video bandwidth manually, independent of the
RBW.
q
Back
— Returns to the previous menu level.
q
Trace
— Activates a menu of trace related functions. Use the corresponding
soft key to select the desired trace function.
q
Max Hold
— Displays and holds the maximum responses of the input sig-
nal.
q
Average (2-25)
— Sets the number of the sweeps to be averaged. The
number of the sweeps can be adjusted from 2 to 25 using the Up/Down ar-
row key, or entered directly with the keypad number keys. Select
OFF
, or
enter 1 to turn off averaging. Press ENTER to accept the selected value.
This feature uses a measurement routine that averages samples over a
user-defined number of successive sweeps. The averaging is done on a
point-by-point basis. Each displayed point reflects the current measure-
ment associated with that point averaged with the measurements associ-
ated with that point from previous sweeps. This feature can be used to
minimize the impact of transients on the displayed signal and noise.
q
Min Hold — Displays and holds the minimum responses of the input sig-
nal over multiple sweeps. This feature is useful for detecting small, dis-
crete, stable signals in the presence of noise.
q
Trace Math — Pressing the Trace Math key in Transmission Measure-
ment mode activates a menu of trace-related functions. Use the corre-
sponding soft key to select the desired trace function.
NOTE: For this function, Trace A is always the runtime trace, and Trace B is al-
ways a saved trace. Trace A is displayed as a yellow trace, and Trace B is dis-
played as a magenta trace. Refer to page 3-15 for information on saving and
recalling traces.
q
Recall Trace ® B — Recalls a stored trace into the Trace B buffer.
q
View B /Clear B — Overlays a stored trace over the current trace. If
there is no trace in the Trace B buffer, the Recall Trace list will dis-
play. Select a trace from the menu of saved traces to recall to the
Trace B buffer. Pressing the soft key again turns off the trace overlay.
