Starting a Program

SCPI Introduction

INITIALIZING THE INTERFACE

Refer to your programming language reference manual for information on initializing the interface. To make sure that the bus and all appropriate interfaces are in a known state, begin every program with an initialization statement.

Always start your programs with the commands shown in the following listing. Use the *RST (Reset) common command to initialize Infiniium to a preset state. The :SYSTem:AUToscale command is very useful on unknown waveforms as it automatically sets up the channel vertical scale, time base, and trigger level. A typical instrument setup configures the vertical range and offset voltage, the horizontal range, delay time, delay reference, trigger mode, trigger level, and slope. Notice that the :SYSTem:DEFault and :SYSTem:AUToscale commands should be followed by an *OPC (Operation Complete) common query.

Example programs are provided that show how to setup basic communications. Example are provided for C#.NET, Labview, MATLAB, and Python. Look in the installation folder: \Keysight\Infiniium\Demo\Example Programs

The following command snippet demonstrate starting lines of code for starting and ending your programs.

Infiniium.write('*RST')  # Initialize the instrument
Infiniium.write('*CLS')  # Clear status and error registers
Infiniium.query(':SYSTem:DEFault;*OPC?')
Infiniium.query(':SYSTem:AUToscale;*OPC?')
