With the development of modern science and technology, automation technology has entered people's lives. Automated tools eliminate the need for repetitive and cumbersome manual operations, greatly improving the convenience of work and life. In the field of measurement, the manual operation of the instrument can also be changed to a computer-controlled automatic test, which greatly reduces the operation time and greatly improves the accuracy of the operation.
To achieve automated operation of equipment and instruments, a "Swiss Army Knife" is required.
I. Swiss Army Knife for Instrument Automation---SCPI
SCPI: SCPI (Standard Commands for Programmable Instruments) is a standardized instrument programming language based on the existing standards IEEE488.1 and IEEE488.2. Compatibility of the programming environment is ensured through the use of standardized programming information, instrument response and data formats. In general, it is divided into SCPI commands formulated by general commands and instruments.
The SCPI general commands are independent of the instrument's measurements and are primarily used to control resets, self tests, and state operations, and the set of operations starts with * and has no hierarchy.
For example: *IDN can be used to get basic information about the device.
The specific control commands of the SCPI instrument are used to perform measurements, read data, and control instrument settings. At the same time, such commands follow a "tree structure" and usually consist of three parts: keywords, parameters, and comments. The SCPI command tree can be divided into multiple subsystems. Each subsystem consists of a root command and one or several hierarchical commands. The command format is: keyword "parameter": keyword "parameter": keyword "parameter"...
For example: :TRIGger:MODE EDGE can switch the trigger mode to edge trigger.
Second, the powerful automation foundation provided by the oscilloscope ZDS2000 series
1, hardware support:
The ZDS2000 series oscilloscopes provide three hardware interfaces: LAN, USB, and serial port on the rear panel to meet the oscilloscope connection requirements of users in different usage scenarios. At the same time, borrowing the hardware structure of the Visa library, it is very simple to realize the data communication between the PC and the oscilloscope.
2. Command support:
The ZDS2000 Series oscilloscopes provide powerful SCPI command support. The functional modules of the ZDS2000 series oscilloscopes are divided into 12 large function modules with more than 800 SCPI commands, covering various function points of the ZDS2000 series oscilloscopes.
Third, the oscilloscope ZDS2000 series SCPI use examples
A brief introduction to an application scenario of SCPI. The picture below is a very dense waveform:
How do you adjust it to a clearer level of viewing?
The manual operation is to turn the time base knob until the waveform is clear.
Using SCPI operations requires only one command:
:TIMebase:SCALe 200e-6
