Specification callouts and compatibility guidance

Match accessories to your test equipment. Key specs to check include connector type (BNC, SMA, 4mm banana), voltage and current ratings, impedance for high-frequency probes, and maximum safe working voltage. For oscilloscope probes, select the correct attenuation (1x, 10x) and bandwidth rating to avoid measurement errors. Use the Compare Specs option to pair probes with your instruments' bandwidth and input capacitance.

Accessory bundles and practical kits

Save time by choosing pre-built kits for education and bench use: oscilloscope probe kits, lab lead sets, logic probe bundles and clamp meter accessories. Bundles help ensure connector compatibility and include replacement tips and protective cases - useful for busy labs, makerspaces, and classrooms.

Practical selection tips and compatibility checks

Before buying test accessories, verify instrument inputs, expected signal levels and environments. For high-frequency work, prioritise probe bandwidth and matched impedance. For power measurements, confirm current clamp range and conductor aperture.

Common installation and wiring diagrams

Below is a simple wiring ASCII diagram for using an oscilloscope probe with a DUT (device under test):

 DUT Signal ---- Probe Tip
                     |
                    GND ---- Probe Ground Clip ---- Bench Ground

Ensure ground clips are attached to the same reference to avoid ground loops. For differential measurements, use differential probes or isolated inputs.

Troubleshooting tips

• Incorrect readings: check probe attenuation, bandwidth and probe compensation.
• Noise on measurements: verify grounding and use shielded leads where possible.
• Damaged connectors or tips: replace with compatible tip kits stocked in our All Products index.

Delivery, lead times and procurement support

Most common accessories are held locally for immediate dispatch; specialised or branded items may have short lead times. We support procurement with formal quotes, VAT invoices and bulk ordering for institutions. Check comprehensive stock listings at our All Products page and request a formal quote for bulk or specialised orders: All Products.
