clrdevice

(To be removed) Clear instrument buffer

This visa and gpib object function will be removed in a future release. Use visadev object functions instead. For more information, see Version History.

Syntax

clrdevice(obj)

Arguments

obj

A GPIB, VISA-GPIB, VISA-VXI, VISA-GPIB-VXI, VISA-Serial, or VISA-TCPIP object.

Description

clrdevice(obj) clears the hardware buffer of the instrument connected to obj.

Tips

Before you can clear the hardware buffer, the instrument must be connected to obj with the fopen function. A connected object has a Status property value of open. If you issue clrdevice when obj is disconnected from the instrument, then an error is returned.

You can clear the software input buffer using the flushinput function. You can clear the software output buffer using the flushoutput function.
