Operation and Reference
Reset/Start Sweep
\ Reset/
[start
The [Keset/Start] key performs three functions for the sweep operations:
1. If a continuous or single sweep is in progress, Reset/Start cancels the
displa' ^ sweep is stopped, the current frequency appears in the
2. For single sweeps, the first press of the [Reset/Start] key resets the
sweep to the start of the sweep.
3. .^ter a single sweep is reset, pressing the [Reset/Start] key again
starts the frequency sweep. ^ ^ &
Afx2, Af-f2 (Modify Bandwidth)
In linear sweep mode, the [Afx2] and [Af^2] keys may be used to double or
halve the sweep bandwidth. If either the new sweep start or stop frequency
exceeds the frequency limits, an error message is displayed. These two-keys
have no effect on discrete sweeps.
Single Sweep
The [Reset/Start] key resets the sweep the first time it is pressed. A single
O sweep starts the second time the [Reset/Start] key is pressed. An
I s/crf ^ illuminated Single indicator denotes that a single linear sweep is in
progress. A single sweep sweeps from the start frequency to the stop
frequency over the specified sweep time.
Continuous Sweep
O
Sfart
The [Start] key initiates a continuous (repetitive) sweep. The Cont indicator
adjacent to [Start] key illuminates when a continuous sweep is in progress.
Continuous sweeps move back and forth between the start and stop ■
frequencies in an up/down/up/down... fashion. If the marker is active, it
functions only during the up-sweep. Sweep parameters should be entered
before starting a continuous sweep. See previous discussion on start and
stop frequencies and sweep time.
