Setting Flow Control

The flow control parameter applies only to RS-232 communication. This
parameter allows you to select the type of serial communication used.

You can choose the Soft option if you want the rate of data transmission to
match the rate at which it can be processed by the device. This enables the
computer and the Broadband Source to stop each other from transmitting
by sending a control character (Xoff). They will also be able to restart the
transmission by sending another control character (Xon). This is known as
a “software handshake”.

To set a flow control:
1.
Press the Setup button.

2. Use the up/down or left/right arrow keys to select Flow Ctrl. The

current setting is displayed.

Note: If you are in GPIB mode, the Flow Ctrl cell will display “N.A.” You must

change the communication mode to RS-232 before setting the flow control.

3. Press ENTER, then use the up/down arrow keys to select the type of

flow you want. “None” means no flow control. “Soft” allows the unit or
computer controlling it, to turn the data transmission on or off.

4. Press ENTER to confirm.
