Control Software For Oscilloscopes and Arbitrary Function Generators
Читать на веб-сайте:
TekBench™ is PC software that controls Tektronix oscilloscopes and arbitrary function generators. It offers intuitive instrument control, automated measurement data logging, automated frequency response measurements, and easy waveform exporting with required format to eliminate extra time and effort. It allow users to focus on their experiment rather than learning the instrument.
- Simple connection to instruments
- Intuitive interface to control and monitor instruments
- Easily capture and export results in required formats
- Automated measurement data logging
- Automated frequency response measurements
- Project laboratories and senior design laboratories
Simple connection to instruments
Because of the plug and play USB interface, only a USB cable is needed to connect the instrument to the computer. Without any configuration, the instrument is detected by the software within seconds.

Once connected, double click the instrument icon and the selected instrument will be loaded into the software automatically.

Intuitive interface to control and monitor instruments
When loaded into the software, the instrument has a full screen interface. Instead of spending time studying the user manual, users can find and change parameters at a glance. The following example shows how easy it is to select different measurements on each channel of the oscilloscope in the full screen interface.
Oscilloscope full screen interface
Up to two instruments can be displayed on the same screen and each instrument has an intuitive interface for easy control and monitoring.

Easily capture and export results in required formats
Oscilloscope waveform data is one of the most important test results. TekBench™ supports exporting the waveform data into *.csv format, which can be recalled by the oscilloscope directly.1It also supports *.csv data with no header for easier analysis in other applications.

Also, the results can be exported into *.MAT format, which can be opened in MATLAB directly.
A screenshot of the oscilloscope can be saved to your computer with just a few clicks. When auto update is enabled in the software, the screenshot of the oscilloscope can be updated about every second.2This allows you to monitor the instrument remotely. The updating screenshot can also be projected in a lab to assist the instructor.

1This function is only supported by MDO3000 series oscilloscopes.
2Screenshot updating speed is dependent on the instrument. The MDO3000 series oscilloscope had a one second updating speed during testing.
Automated measurement data logging
Instead of performing a single measurement, use measurement data logging to track the change of the measurement results for more insight into the design.
TekBench™ gives you the option to select 16 of the most common measurements. Data logging can be performed for up to six measurements at the same time. The interval between each measurement result can be set to as low as 2 seconds with a testing time up to 5 days.1
The results can be displayed in trend plot mode with each measurement color coded. It can also be displayed in list or histogram mode, which can provide more insight into the results.
Measurement data logging displayed in trend plot mode
Each of the measurement data logging results are saved automatically in a *.csv file. This file can be exported and imported into the software so previous test results can be accessed for future analysis.
1TekBench™ free version supports a testing time of up to 30 minutes. Option TEKBENCHFL-BAS is needed for testing time up to 5 days.
Automated frequency response measurements
Frequency response is a common measurement in a project lab. The following diagram shows the arbitrary function generator connecting to the input of the testing board while the oscilloscope is connected to its input and output to measure the change of the amplitude.
Frequency response testing connection diagram
In traditional labs, students have to set the output frequency of the arbitrary function generator and record the measurement of amplitude on the oscilloscope. They then need to change the frequency and record another measurement. The following example takes the Frequency Response testing from a Start of 100 kHz to a Stop of 5 MHz with total 101 samples in Linear Sweep mode. Students would have to create around 100 tests on different frequencies, which will take them more than one hour to finish. This method of testing is time consuming and it is easy to make mistakes.
With TekBench™, Frequency Response testing can be finished with just a few steps:
- Set the AFG output amplitude
- Select the sweep type and input the number of samples
- Click the start button
The testing will start automatically and Frequency Response curve, plotted as frequency versus gain1, is created.

1Gain = 20 log10(output amplitude / input amplitude).
