Setting Measurement Conditions

Specifying Sweep Times and Stopping Sweep

You can specify the number of times sweeping is actually executed upon occurrence of a

trigger. After sweeping is repeated the specified times, the sweeping is stopped and no

further sweeping is executed by any trigger that may follow. You can also set the sweeping

to unlimited times (continuous sweep).

Sweeping by specified times and stopping a sweep are selected and executed by a sweep

mode. Pressing the

[Trigger] key will display the following sweep modes:

The operating instructions for each sweep mode are shown below.

Single sweep

Step 1. Press the [Trigger] key to display the trigger menu.

Step 2. Press the

SINGLE key once to select single sweep.

Step 3. Use the method selected in “Selecting a Method to Start Measurement (Trigger Source)”

on page 111 to trigger. When the triggered single sweep ends, sweeping is put into the

stopping (hold) state. No further sweeping can be triggered after it is stopped.

NOTE When the internal trigger (free-run) is selected in “Selecting a Method to Start

Measurement (Trigger Source)” on page 111, new sweeping starts immediately after step 2

above is performed, and sweeping is put into the stopping state after a single sweep ends.

This means that only pressing the

SINGLE key will allow you to perform a single sweep.

Sweep by specified times

Step 1. Press the [Trigger] key to display the trigger menu.

Step 2. Press the

NUMBER OF GROUPS key. This will display the current value for the number of

sweeps (sweep groups) to be swept out of the specified number of sweeps in the parameter

settings located in the upper left area of the screen.

Step 3. Use the numeric keys in the ENTRY block (

[0] to [9]) to input a new value for the number

of sweeping times and then press the

[´1] key.

NOTE The number of sweeping times described above cannot be entered with the rotary knob (m

or step key ([][¯]).

Step 4. Use the method selected in “Selecting a Method to Start Measurement (Trigger Source)”

on page 111 to trigger. When the triggered single sweep ends, sweeping is put into the

Softkey label Sweep mode
