SWEEP Displays the Sweep function soft key menu for the current operating mode.
Sweep Menu Provides for changing the display resolution, single or continuous sweep, and
access to the Trace Math functions.
Choosing
SWEEP in FREQ or DTF measurement modes causes the soft keys
below to be displayed.
q
RESOLUTION — Opens the display to change the resolution. Choose 130,
259, or 517 data points. (Not active in DTF mode. In DTF mode, resolution

q
MAX HOLD ¾ Activates the max hold function. It displays and holds the
maximum response of the input signal trace.
q

q
OCC BW (second level)
q
METHOD ¾ Selects the method to be used, dB Down or % of Power.
q
% ¾ Enter the desired % of occupied bandwidth to be measured.
q
dBc ¾ Enter the desired power level (dBc) to be measured.
