Automotive Accessories for Oscilloscopes

Test Leads

CAN Test Box (PP619)

The CAN Test Box gives you easy access to the 16 pins of the diagnostic connector that is fitted to all modern vehicles. Depending on the configuration of the vehicle, this may allow you to check power, ground and CAN Bus signal quality. With the test leads supplied you can connect your PicoScope automotive scope, or any other suitable scope, to the CAN Test Box to monitor any signals present, such as the CAN High and Low signals.

Automotive Test Leads (TA000 and TA020)

The TA000 test lead has been custom made for automotive use with a Pico automotive oscilloscope. Its length (3 meters / approx 10 ft) allows the oscilloscope to be placed on the work bench away from the car being tested / repaired. A wide range of probes, clips and gators can be plugged into the 4 mm connectors at the end of the cable. The cable is fully screened to reduce noise pickup.

Also available is the TA020 automotive test lead. The TA020 is a 5 meter (approx 16 ft) version of the TA000.

6-Way Universal Breakout Leads

Pico’s universal 6-way breakout leads eliminate the need to own many specific breakout leads for engine diagnostics. The breakout leads are available with 4 different sizes of connectors: 0.6 mm, 1.5 mm, 2.3 mm and 2.8 mm.

The breakout lead is simply connected into the existing cable loom and enables voltage readings to be taken from the numerous sensors in the engine compartment. The output signal can then be taken from the 4 mm banana plugs into the input of the PicoScope oscilloscope using the TA000 test lead.

2-Pin Automotive Breakout Lead (TA012)

The TA012 breakout lead enables voltage readings to be taken from the numerous sensors in the engine compartment. The breakout lead is simply connected into the existing cable loom, and the output signal can then be taken from the two 4 mm banana plugs into the automotive oscilloscope using the TA000 test lead.

Note: A TA000 test lead will be required to convert the 4 mm banana plug connection on the TA012 into a BNC connector suitable for plugging into the PicoScope.

Fuse Extension Leads (PP408)

Do you need to measure the current through a circuit but can’t find anywhere on the vehicle where you can connect your current clamp?
Fuse extension leads are a simple accessory that can save you valuable time.

Fuse extension leads are quick and easy to use: simply remove the fuse (of the circuit you wish to test) from your fusebox and replace it with a fuse extension lead. Now insert the fuse into the extension lead. To measure the current drawn, just connect your Pico current clamp to the extension lead.

A set of 2 fuse extension leads are supplied, allowing you to use the leads with both ATC and mini-ATC style fuses.

60 MHz Oscilloscope Probe (MI007)

This high-quality general purpose oscilloscope probe has a 60 MHz bandwidth. A two position slide switch allows attenuation of either x1 or x10 to be selected.

This probe is particularly useful if you want to probe CAN bus and FlexRay signals.

20:1 Attenuator (PP198)

The PP198 has been designed to allow fuel injector and primary ignition waveforms to be measured using PicoScope oscilloscope products.

The PP198 is a passive 20:1 attenuator. This means that a 20V signal at its input will appear as a 1V signal on the output. As the signal is attenuated, the PP198 allows voltages of up to 300 V to be measured.

Please note this attenuator should not be used for any high voltage measurements other than fuel injectors and primary ignition.

S-hook (MI168)

This small but essential accessory makes it easy to keep all those test leads tidy in the engine bay.

The S-hook is about 100 mm (4 in) long and coated in plastic and rubber to protect the vehicle's paintwork and your cables. Hook one end underneath the bonnet or hood, and use the other end to hang a bundle of cables up to about 25 mm (1 in) thick.
