Fast Sampling

The PicoScope 4823 can capture high-speed signals that are too fast for many other automotive oscilloscopes. With sampling rates of up to 80 million samples per second, there is nothing that can escape the scrutiny of PicoScope.

CAN and FlexRay are now common on vehicles, and new protocols such as SENT for digital sensors and CAN FD (up to 5x faster than the current CAN standard) now present in some vehicles. The fast sampling rate ensures that the PicoScope 4823 has the speed to handle future needs as vehicle technology changes.

Crisp, clear high-resolution display

A deep waveform memory gives you a high time resolution, but a high vertical resolution is equally important. It allows you to see small changes in signal such as ignition coil oscillations and the small dip in current when an injector opens.

Many oscilloscopes only offer 8-bit resolution which allows 256 vertical steps. As most PC monitors have vertical resolutions of over 1000 pixels, this results in a low-resolution “blocky” display. The PicoScope 4823 has 12-bit resolution (4096 steps), and when not using the full sampling rate of the scope this can be enhanced to 16 bits (65 536 steps).

Memory Buffer

The best way to diagnose an intermittent fault is often to set up the scope to measure from several components and wait for the fault to occur. For an intermittent misfire, you might want to capture several minutes of cam, crank, ignition and injector waveforms. These types of tests require an oscilloscope with a “deep” memory buffer, so that you can capture for long periods of time and then zoom in without any gaps or loss of detail.

With PicoScope you can collect 250 MILLION samples, more than any other automotive oscilloscope. Our advanced “always on” memory technology uses hardware acceleration to make sure that the processing of large amounts of data does not slow the oscilloscope down even when you are using a slower or older PC.

Deep memory allows long recordings at high speed – you capture a complete test drive whilst looking for intermittent faults. When not using the full memory for a single waveform, PicoScope automatically stores up to the last 10,000 waveforms in the buffer, so you can stop the scope and “wind back time” to see every capture.

Advanced features

Most new users start by using the guided tests to configure all the settings automatically. As your experience grows there are many advanced features to explore. These include:

• Advanced digital triggers. Unique among automotive oscilloscopes, these trigger modes allow you to trigger when there is too long a time gap (such as when an injector fails to fire). They can also be set to trigger and sound an alarm when a sensor signal goes out of range.
• Filters. Some signals are noisy as wires in the loom pick up noise from other wires. The ECU filters this noise out. The PicoScope 4823 has selectable hardware filters to remove this noise, so you see what the ECU sees.
• Ffrequency measurement. Flow sensors and some airflow sensors output a digital frequency signal. Most oscilloscopes can’t extract usable diagnostic information from this, but your PicoScope can convert it to a conventional analog waveform (as shown in this MAF sensor example).

Every aspect of your PicoScope has been designed for a long working life, and it has the performance to ensure it will not be obsoleted by the changing technology in new vehicles. The hardware is robust and reliable with no moving parts or batteries to fail. Combine this with free support and free software updates for the life of the product and its easy to see why a PicoScope is the choice for professional diagnostics.

USB 3.0 for power, speed and simplicity

As with all our automotive PicoScope oscilloscopes, no external power supply is required and there are no batteries to go flat, just a simple reliable connection to the USB port.

The PicoScope 4823 has the latest SuperSpeed USB 3.0 port to interface to your PC. Don’t worry if your PC only has USB 2.0 ports – the PicoScopes are fully compatible with these too. If you have USB 3.0 on your PC you will notice slightly faster screen update rates, faster file saving and USB streaming. As more of our customers move to PCs with USB 3.0, free software updates will ensure that you get the full benefits available from the new standard.

Our unique fast USB streaming allows continuous gap-free data to be collected straight to PC memory. This makes features like our cylinder balance, battery test and (optional) NVH tests possible. It also allows the oscilloscope to display live, real-time data without waiting for the screen to refresh.

Common ground vs Floating inputs

The 2 and 4 channel automotive PicoScopes feature floating input channels – a unique technology that allows safe, low-noise measurements even in situations where none of the inputs are grounded.

In contrast, the 4823 features a common ground connection where grounding any one input also grounds all the others.

On the 4823, the USB ground of the PC connection is also linked to the ground on the BNC outer connectors. In order to minimise the risks to scan tools and other equipment connected to the PC, the 4823 includes special  (self-resetting) protection fuses on the inputs limiting any unwanted current flow on the ground in the event that the ground is incorrectly connected.

Arbitrary waveform and function generator

The PicoScope 4823 has a built-in low-voltage function generator (sine, square, triangle, DC level ­and others) and arbitrary waveform generator. The output voltage range is ±2 V, and so an external amplifier will be required for most workshop applications.

As well as basic controls to set level, offset and frequency, more advanced controls allow you to sweep over a range of frequencies.

The 14-bit 80 MS/s arbitrary waveform generator (AWG) can be used to emulate low-voltage signals. AWG waveforms can be created or edited using the built-in AWG editor, imported from oscilloscope traces, or loaded from a spreadsheet.
