Frequency Sweep

7
A sweep consists of a finite number of small frequency steps. Since each
step takes the same amount of time, longer sweep times result in smaller
steps and therefore better resolution.
The number of discrete frequency
points in the sweep is automatically
calculated by the function generator
and is based on the sweep time you select.
Frequency Sweep
For triggered sweeps, the trigger source can be an external signal,
the key, or a command received from the remote interface.
The input for external trigger signals is the rear-panel Trig In
connector.
This connector accepts TTL-compatible levels and is referenced
to chassis
ground (not floating ground). When not used as an input, the Trig In
connector can be configured as an output to enable the 33250A to trigger
other instruments at the same time as its internal trigger occurs.
