Laptop Oscilloscope Software

[Herminia Remmen]

TheDiesel Scope is a Digital Storage Oscilloscope geared for the heavy-duty diagnostics community. Diesel Laptops has partnered up with the leading manufacturer in automotive oscilloscope technology to bring the first Heavy vehicle and equipment geared oscilloscope to the market.

A digital Storage oscilloscope or DSO is a tool that is used to diagnose electrical problems that cannot normally be seen with a standard automotive multimeter. A DSO allows a technician to capture voltage readings over a period of time and view that information graphically. This allows the technician to get very detailed in their diagnostics and find issues that cannot normally be seen with a standard diagnostic tool. If you were to think of a normal handheld multimeter as a film camera that takes in a small amount of light to create a picture, then you can think of an Oscilloscope as a High definition video camera that lets you take detailed information over an extended period of time!

The diesel scope will allow technicians to perform tasks in minutes that would normally take hours and hours of removing components and wasted time and parts. Removing valve covers and inspecting valvetrain components on modern commercial diesel vehicles can be a daunting task but hooking up the diesel scope and running a few common tests can lead the technician down the correct path to a successful and efficient repair.

The diesel scope offers all the functionality of the standard Picoscope tools, with the added benefit of the incorporated Guided Diagnostic tests specifically for Medium and Heavy-Duty Vehicles. These tests will help walk technicians through specific tests as well as give them examples of good waveforms to compare with. This expanding library of guided tests will keep new and more efficient ways of doing things at the forefront of your diagnostics.

Our Ex-Diesel Technician tech support team is on standby and have been trained in oscilloscope diagnostics. If you have issues or trouble connecting your scope to a piece of equipment or need help performing tests, our tech support team is here to help.

Backed by the leader in Automotive oscilloscopes. Pico Technology was established in 1991 and soon became a leader in the field of PC Oscilloscopes, data loggers and automotive diagnostic equipment.

The difference between PC-based USB oscilloscopes (referred to as a USB oscilloscope) and stand-alone oscilloscopes is that a USB oscilloscope does not have buttons or a screen and is connected to a computer through a USB. The device is then controlled by the computer, and results are displayed on the computer screen. The following picture is an illustration of a USB oscilloscope in use:

Compared with stand-alone oscilloscope, PC-Based USB Oscilloscopes have the following advantages:

1. Small size, easy to carry.

2. PC screen is larger so the waveforms can be seen more clearly.

3. No screen component so the price is lower.

4. PC interface makes it easy to process and edit files.

5. Users can design their own programs to control the oscilloscope.

Many USB oscilloscope software use a conventional window design because it is the easiest to design. However, such a design does not comply with the actual use of oscilloscopes and causes difficulties and inconvenience for users.

In the overview function, the top of the screen shows the entire waveform and the magnified portion of the waveform is shown below that. The grey area can be dragged at the top or the scroll bar at the bottom can be used to change the section displayed.

The equivalent sampling function: for periodic signals, this function analyzes signals and graphs them at a sample rate of 4 GS/s. It increases the sampling resolution and provides the user with more details.

The logic analyzer mode can decode bus data and save development time. This Mode can decode common protocol such as: I2C, UART, I2S, PS2, CAN Bus, 1-Wire, S/PDIF, Lin Bus, Microwire, Miller, Manchester, SM Bus, and Modbus. Will continue to be added and free update.

Perytech USB Oscilloscope comprises a black aluminum alloy case with an excellent texture. The alloy case receives hair-line surface treatment to ensure the exterior is very trendy. The exterior is very trendy, with great texture. The device is small, light, and convenient to carry.

*The hardware trigger is an important part of an oscilloscope. Some low-priced oscilloscopes do not include this feature because it increases the cost, however, absence of this feature leads to numerous problems. Please view the following video to understand the importance of hardware triggers:

The AUX-out jack on laptops outputs sound in analog rather than digital signals. Unless I am mistaken in my thought process, in theory, I should be able to somehow display this signal on an oscilloscope.

The only input the oscilloscope I have has is a CH/BNC input and digging through the lab equipment I have found a device that fits into the CH jack and has two crocodile clips (red/black) coming out of it.

I have access to a male-to-male aux (3.5mm) cable. Is there anything I can do with this setup to view the audio signal outputting from my laptop on the oscilloscope? Looking around online did not help my particular case. I thought of connecting a microphone to the oscilloscope and placing this mic next to my laptop's speaker, however this is obviously less accurate (variable mic quality, takes in background noise, etc.)

Take a scope probe, connect the ground clip to the metal barrel of the 3.5mm aux connector and the probe itself to the tip of the connector. Plug the other end of the male-male aux lead into the aux output. You will now get one channel on the scope, provided you've set it up correctly.

You could take a 3.5mm cable of any kind (perhaps from a broken headphone), cut off whatever is on the other end and put one wire under each of the binding posts. If your oscilloscope and computer are both grounded to earth you will have to get the wire that's connected to the chassis of the computer on the black binding post.

My assumption is that there isn't a direct tie between earth ground and reference ground on the arduino when powering over pins (via an isolated bench power supply,) even if usb is connected, but it's a fairly unsafe assumption.

Basically, is there some isolation I'm overlooking, or should I consider any connection to an earth grounded PC as potentially explosive and simply move my workflow to a battery powered laptop whenever an oscilloscope is involved?

It's my understanding that if I accidentally touch the wrong thing on the arduino The oscilloscope may potentially short to earth-ground. That's not a big deal with respect to the 3.3v/5v rail at a fraction of an amp on the arduino, but I don't know exactly what the relationship between usb and my computer's 1000w power supply is.

But my general rule of thumb with anything that is earth grounded is to not touch it with the scope, in case I mistake a pin/pad for positive when it is in fact neutral/ground, or in general just connect something that ought not to have been connected.

Again, if this is overly paranoid I would just like to know why (is there something inherent to usb that makes a short of this kind relatively harmless? 5v 2a seems like it could fry a decent amount of small components, if not the scope, necessarily.)

Most laptop power supplies are ground-isolated, and of course if you are running from batteries there is no earth ground. But if you have a printer (or something) connected, it may be earth-grounded through that. Or, your Arduino may have an earth-ground so that would earth-ground your laptop when plugged-in.

You CAN blow the current fuse on a DMM when measuring current or by accidently measuring current when you're trying to measure voltage. That's pretty common. Meters also have a maximum voltage (usually 600V or so) but you won't fry it with a couple-hundred volts when it's on a low-voltage scale, or when it's set to measure resistance, etc.

This was the answer I was looking for. I'm just going to use the laptop if I need to measure something. Yes, it would be my fault if I connect the wrong lead to the wrong thing, but if it's a diode on half an amp the world doesn't end. I'd rather not risk it with hundreds or thousands of dollars of hardware.

Depending on where you are the power grid, and thus what neutral/ground means, varies. So the answer to the question, "is my PC neutral connected to earth ground" is dependent on region. In the US, you can pretty much expect a pc to tie neutral to ground, but unfortunately "region" is the best I can say for anywhere else, because Europe doesn't necessarily follow one pattern, the Americas don't follow one pattern (North America is mostly the same,) and so on.
