Arbitrary Waveform and Function Generator

A useful addition is an arbitrary waveform and function generator, which allows you to simulate waveforms to test and stimulate actuators and mimic responses from sensors. Please note that you may need a special isolator, buffer amplifier or driver to use this feature successfully in the field due to the relatively high impedance and low over-voltage specification of the output. Please contact us should you require any assistance with this feature.

Deciding between a 4425A and a 4823

4425A 4-Channel PicoScope - Front View

The 4425A is much more rugged than the 4823. It has a convenient hanging strap and a rubber boot to protect it in the harsh automotive environment. Its inputs can withstand much higher voltages than the 4823 (250V vs 100V). It has floating grounds and has a much higher sampling rate (400MS/s vs 80MS/s). The 4823 has many specialised applications but the general workshop technician should, as a general rule, always choose the 4425A unless there is a really pressing need for an eight channel instrument.

4823 8-Channel Automotive Oscilloscope in use Using the 4823 8-Channel Automotive Oscilloscope

Pico Automotive have introduced a new 8-channel Automotive Oscilloscope called the 4823. It is the world's first high-resolution, 8-channel automotive oscilloscope fast enough for CAN, CAN-FD and FlexRay, including serial data decoding.

Why are 8 channels necessary?

PicoScope 4225A, 4425A and 4823 Automotive Oscilloscopes

Eight channels facilitates testing of five, six and eight cylinder engines. V6 / V8 CAM timing (4/6 cams plus crank, and sometimes a WPS500X Pressure Sensor), and VVT timing systems. Trucks, earthmoving and agricultural vehicles often require a mix of electrical and hydraulic measurements on multiple valves simultaneously to diagnose problems with system interaction. The 4823 is ideal for full system diagnosis on components (including power, ground, signals, current) and general engine diagnostics where many signals need to be monitored simultaneously.

The 4225A and 4425A vs the new 4823 PicoScope

The 4823 is very similar to the 4225A and 4425A oscilloscopes (i.e. 12 bits, 20 MHz) but there are a few specifications and features that are different. Please refer to the specifications for full details. We have summarised notable differences below:

Pico 4225 Pico 4425 Pico 4823
Channels 2 4 8
PicoBNC+ Yes No
Arbitrary Waveform & Function Generator No Yes
Floating Grounds Yes No
Input Range 200V 50V
Input Protection 250V 100V
Buffer 200MS 256MS
Maximum Sample Rate 400MS/s 80MS/s

4823 8-Channel Automotive Oscilloscope Specifications

The 4823 is similar to the 'Test and Measurement (electronics)' 4824, except that it has protection fuses on its inputs and can be used with the PicoScope Automotive software.
