Selecting the Frequency Sweep
Use
Frequency sweep is the process where the resolution filter covers a defined
frequency range.
Sweeps may be performed continuously (CONT SWEEP) or once (SIN-
GLE SWEEP).
Starting a
continuous sweep
•
Press the
function key
in the
submenu
.
The sweep repeats continuously when the trigger event is detected ( 6-
140).
Performing an
n-times sweep
1.
Press the
function key
in the
submenu
.
An n-times sweep is started when the trigger event is detected. The
number of sweeps is specified with the NO. OF SWEEPS setting ( be-
low).
When you repeatedly press the
function key, the previous trace
is cleared and a new frequency sweep (n times) is started.
Setting the
number of sweeps
2.
Press the
function key
in the
submenu
.
An entry field containing the current setting is displayed. The default set-
ting is 0 (endless sweeps).
3.
Enter a new value ( 5-60).
The entry range for the number of sweeps is:
0
≤
Cycle Count
≤
32767
The new setting is saved and when a single sweep has been started, the
sweep is repeated n times.
Repeating an
n-times sweep
4.
Press the
function key
in the
submenu
.
An n-times sweep is started when the trigger event is detected. The trace
is not cleared on completion of the sweep as would be the case with the
single-sweep function.
This is most relevant in relation to the TRACE AVERAGE and HOLD
functions if measured values that have already been recorded have to be
taken into account for averaging and finding the minimum/maximum.
