System Commands 29
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 747
:SYSTem:DSP
Command :SYSTem:DSP "<string>"
The :SYSTem:DSP command writes a quoted string, excluding quotation
marks, to the advisory line of the instrument display. If you want to clear
a message on the advisory line, send a null (empty) string.
<string> An alphanumeric character array up to 86 bytes long.
Example This example writes the message, "Test 1" to the advisory line of the
oscilloscope.
myScope.WriteString ":SYSTEM:DSP ""Test 1"""
Query :SYSTem:DSP?
The :SYSTem:DSP? query returns the last string written to the advisory
line. This may be a string written with a :SYSTem:DSP command, or an
internally generated advisory.
The string is actually read from the message queue. The message queue is
cleared when it is read. Therefore, the displayed message can only be read
once over the bus.
Returned Format
[:SYSTem:DSP] <string><NL>
Example This example places the last string written to the advisory line of the
oscilloscope in the string variable, strAdvisory. Then, it prints the contents
of the variable to the computer's screen.
Dim strAdvisory As String ' Dimension variable.
myScope.WriteString ":SYSTEM:DSP?"
strAdvisory = myScope.ReadString
Debug.Print strAdvisory
