5.5.1 Setting General Recording Options

Use the General tab of the Recording Options dialog to define generic recording settings.

To set general recording options:

Step 1 Open the Recording Options dialog.

The General tab is displayed by default.

Step 2 Set the Recording Type. Recording Type choices are as follows:

• Snapshot — A snapshot recording works similarly to using a tape

recorder: recording begins when the Record button is pressed, and it stops

when either the Stop button is pressed or the buffer is filled.

• Manual Trigger — A manual trigger recording begins when the Record

button is pressed. Recording continues until either the Trigger button or

the Stop button is pressed in the application. If the Trigger button is

pressed, recording will stop automatically when the amount of data

specified by the Trigger Position has been collected.

• Event Trigger — An event trigger recording begins when the Record

button is pressed. Recording continues until either the trigger conditions

are met or the Stop button is pressed in the application. If the trigger

conditions are met, recording will stop automatically when the amount of

data specified by the Trigger Position has been collected.

Step 3 (Optional) Select from the following Options:

Beep When Trigger Occurs — When this option is selected, a beep will

sound when the trigger event is detected.

Step 4 Set the Buffer Size. Use the slider or the arrow keys on the keyboard to adjust

the buffer size. It can be set anywhere between 100 kilobytes and 32

megabytes. This determines the amount of data that the analyzer will record.

Please note that because of the way that packets are stored in the analyzer’s

memory, the buffer size doesn’t exactly represent the amount of Bluetooth

traffic that will be recorded.

Step 5 Set the Trigger Position (for event trigger recordings only). Use the slider or

the arrow keys on the keyboard to adjust the trigger position. It can be set

anywhere between 1 and 99%. This determines the amount of data that will

be recorded before and after the trigger event. For example, if the slider is set

at 30% post-triggering, then the first 70% of the data in the recording will be

things that happened before the trigger, and the last 30% will be things that

occurred after the trigger.

Step 6 (Optional) Enter an Options Name. You can use the options name to identify

the current set of recording options. If you save the settings, then the next

time the options file is loaded, the options name is displayed in this text box.
