Marker Frequency

If desired, you can set the frequency at which the signal on the front-
panel Sync connector goes to a logic low during the sweep. The Sync
signal always goes from low to high at the beginning of the sweep.
• Marker frequency: 1 µHz to 80 MHz (limited to 1 MHz for ramps and
25 MHz for arbitrary waveforms). The default is 500 Hz.
• When the sweep mode is enabled, the marker frequency must be
between the specified start frequency and stop frequency. If you
attempt to set the marker frequency to a frequency not in this range,
the function generator will automatically set the marker frequency
equal to the start frequency or stop frequency (whichever is closer).
• The Sync signal setting is overridden by the setting of the Marker
frequency used with the sweep mode (see page 62). Therefore, when
the marker frequency is enabled (and the sweep mode is also enabled),
the Sync signal setting is ignored.
• Front-Panel Operation: After enabling sweeps, press the Marker
softkey. Then use the knob or numeric keypad to enter the desired
marker frequency.
• Remote Interface Operation:
