Sweep Mode Pressing this softkey reveals a menu of choices for
determining the sweep state and mode. Using its submenu
selects an RF sweep, or an LF sweep, or an amplitude
sweep. Pressing Sweep Mode > off turns off an on- going
sweep, and the output signal is then set according to the
current and hardkey settings.
• Default value: Off
• Key sequence: > Sweep Mode
RF Pressing Sweep Mode > RF softkeys enables an RF sweep
output via the RF OUT port. The amplitude is at a constant
level defined by the
hardkey.
Key sequence: > Sweep Mode > RF
According to different sweep trigger and point trigger
configuration cases, the signal generator produces an RF
sweep differently:
Case 1. Sweep trigger and Point trigger are both set to
Immediate: the signal generator initiates an RF sweep over
the points immediately and automatically.
Case 2. Sweep trigger and Point trigger are both set to Key,
pressing > Sweep Mode > RF arms an RF sweep and the
signal generator requires you to press the hardkey to
initiate a sweep and also press the hardkey to sweep
over each of the points.
Case 3. Sweep trigger is set to Key while Point trigger is set to
Immediate, pressing > Sweep Mode > RF arms an RF
sweep. The signal generator requires you to press the
hardkey to initiate the sweep and the signal generator will
sweep over the points automatically.
Case 4. Sweep trigger is set to Immediate while Point trigger is
set to Key, pressing Sweep > Sweep Mode > RF initiates an RF
sweep immediately, but the signal generator requires you to
press the hardkey to sweep over each of the points.
If you want to use an external trigger source, a TTL signal
with 100 ns as the minimum level holding time is required.
