(2)Step sweep
The frequency or level is swept from the start until the stop by specified
step.
The number of sweep points can be set in the range from 2 to 65,536.
The sweep rate is the same as list sweep.
In addition, the linear sweep or logarithm sweep can be selected at step
sweep.
Note
Max. 3ms
Sweep rate 800μs
10N-3(MHz)
800μs
The sweep rate is changed to 3ms at frequency points of 10N-3(MHz)
(N: integer).
Display of sweep waveform
The waveform swept is displayed by frequency or level vs. time.
Sweep control by trigger signal
By a trigger signal supplied to TRIG IN connector, the sweep can be
controlled. There are four types of trigger modes as shown in the figure
below.
External/manual trigger

Trigger source and synchronous output
Trigger source can be selected among free run, external and manual .
■
External
If the trigger source is external, "TRIG IN" connector on the front panel is
used.
·
Input frequency range :
DC to 5MHz
·
Input voltage range :
1 to 10Vp-p
·
Trigger level :
0.56V(fixed)
·
Input register :
approx.36kΩ
Example 1. Repeat sweep/EDGE 1

Example 2. Repeat sweep/free run

Synchronous output
more than 50μs
■
Synchronous output
The high level is output to synchronous output on the rear panel during
the sweep.
If the sweep is continuous, low level of more than 50μs is output when
each sweep is completed.
