ECE Student Success Toolkit - Cool Oscilloscope Benefits

Blog Post created by BradJolly Employee on Sep 4, 2018

An electrical and computer engineering (ECE) student studying waveforms, noise, and signal modulation must generate and view a signal. Lab equipment is sometimes in short supply, and if no function generator is available, there may be no signal to view.

 

Fortunately, many Keysight InfiniiVision X-series oscilloscopes can generate a wide variety of training waveforms. Press [Help] > Training Signals, to select from a menu of training signals:

 

Then connect a 10:1 probe between the [Demo Probe Comp] output (including ground) and the channel [1] connector. This enables you to work with the training signal.

In addition, some Keysight oscilloscopes have built-in waveform generators. Look for a G on the end of the product number, such as EDUX1002G. In the 1000X series, the EDUX1002G and the DSOX1102G have a built-in waveform generator.

 

The higher performance models (2000/3000/4000/6000 X-series) all have the waveform generator built in, but it requires a license to be enabled. The easiest way to check is to push the [Wave Gen] button on the front panel; if it lights up, it is enabled.

 

The oscilloscope’s front panel contains the waveform generator’s [Gen Out] output connector and a [Wave Gen] key to configure the waveform generator.

 

After you press [Wave Gen], press the Waveform or Settings softkey to configure the waveform and its output hardware.

Softkey

Capabilities

Waveform

Sine, Square, Ramp, Pulse, DC, or Noise

Settings

Logic Preset: TTL, CMOS . . .

Enable/disable waveform

Output impedance: High-Z or 50 Ω

Sync trigger

Add noise

Modulation: Frequency (FM), amplitude (AM), frequency-shift keying (FSK)

 

You can also program the waveform generator with the Standard Commands for Programmable Instruments (SCPI) language. The instrument’s display provides clear feedback to help students quickly learn about various waveforms, modulation, the SCPI programming language, and the oscilloscope.

 

Finally, note that you can press and hold any front-panel key to obtain help on that key. For example, here is the help associated with the [FFT] key.

 

You can also press the [Help] key to change the language in which the push-and-hold help is displayed.

 

When the language is set to Japanese, pushing and holding the [FFT] displays the following text.

 

In short, ECE students can use an inexpensive oscilloscope with built-in waveform generation capabilities to learn several fundamental concepts, learn how to use the instrument, and to replace a function generator for basic applications.

To help students and educators quickly learn to analyze a variety of signals with an oscilloscope, Keysight has put together an “Educators Kit” that can be used with all InfiniiVision oscilloscopes. This kit is available for free download at https://www.keysight.com/en/pd-1952427/educators-training-kit-for-infiniivision-2000-and-3000-x-series-oscilloscopes?cc=US&lc=eng
