What Cal Test Electronics does
Cal Test Electronics, Inc. is a privately held manufacturer of test and measurement accessories founded in 1995 and headquartered in Yorba Linda, California. The company designs and sells physical accessories — oscilloscope probes, banana and tip connectors, coaxial connectors, test leads, cable assemblies, test clips, and kit assortments — used by engineers, technicians, and educators working with oscilloscopes, multimeters, and other bench or field test equipment. Its probe line includes the CT4560 Series of 14 passive voltage oscilloscope probes spanning 55 MHz to 500 MHz with voltage ratings from 55 Vrms to 4 kVrms and 1% measurement precision on select models, all backed by a two-year warranty. Products are designed to comply with IEC 61010, CAT III, CAT IV, RoHS, and REACH standards.
Cal Test distributes exclusively through authorized channel partners — primarily DigiKey, Mouser Electronics, Newark, and TestEquity LLC — supplemented by direct custom-engineering engagements for OEMs. The company generates revenue primarily through unit-priced hardware sales (most products between $5.75 and $140, with custom and rack configurations up to $605), with secondary streams from calibration/repair services (NIST-traceable calibration, 10-15 day turnaround) and custom test solutions engineering for instrument manufacturers under NDA. It also offers an online Test Lead Builder configurator, an Educational Rebate Program (10% discount on $5,000+ orders to accredited institutions), and operates a sub-brand called Global Specialties serving the education market with electronic trainers and breadboards.
The business is privately held with 1-10 reported employees, no disclosed parent or institutional investors, no funding rounds, and no public revenue figure. Cal Test has demonstrated continuous operation for over 30 years, an active product development cadence through 2025-2026, and compliance documentation covering RoHS, REACH, California Proposition 65, Conflict Minerals, and PFAS. Its go-to-market is distribution-led and its operating geographies span North America with global channel reach via the major authorized distributors.

Cal Test Electronics competitors and assessment
Company assessmentDirect peers
- Pomona Electronics: Direct competitor manufacturing test leads, probes, banana plugs, coaxial connectors, and test accessories for oscilloscopes and multimeters — almost identical product category and customer base to Cal Test Electronics.
- Mueller Electric: Long-established manufacturer of test clips, alligator clips, banana plugs, and test leads — directly comparable to Cal Test's Test Clips and Banana/Tip Connector product lines.
- Hirschmann (Bel Fuse): Manufacturer of high-quality test leads, probes, and connectors used in measurement and diagnostics — overlaps with Cal Test's coaxial connectors, test leads, and cable assemblies for industrial test applications.
Broad incumbents
- Fluke Corporation: Industry-leading test and measurement equipment and accessory maker (owned by Fortive). Overlaps with Cal Test in probes, test leads, and accessories, but operates at vastly larger scale and broader product portfolio including full handheld instruments.
- Tektronix: Oscilloscope and test equipment leader whose own-brand and third-party passive/active probes and accessories overlap directly with Cal Test's probe and cable assembly portfolio. Serves the same engineering test-and-measurement use case.
- Keysight Technologies: Major test and measurement equipment vendor (spin-out of Agilent/HP) selling oscilloscopes, signal analyzers, and associated probes/accessories. Comparable in target customer (test engineers) though at much higher price points and broader scope.
Emerging players
- GW Instek: Test and measurement equipment maker (oscilloscopes, power supplies, signal generators) that competes at lower price points and overlaps with Cal Test in education/bench-test accessories and global distribution channels.
- B&K Precision: Test and measurement instrument maker (power supplies, oscilloscopes, signal generators) that also sells associated probes and test accessories — adjacent catalog overlap with Cal Test's probe and DC power supply products.
Regional players
- Saelig Company: North American-focused distributor of unique test and measurement products including probes and accessories. Comparable go-to-market overlap (specialty T&M distribution channel) though Saelig is primarily a distributor/reseller rather than manufacturer.
Others
- Global Specialties (sub-brand of Cal Test): Cal Test's own educational sub-brand competing with standalone trainers/breadboard makers like Elenco, Phidgets, and Lab-Volt — included because it represents an in-house adjacent competitor/portfolio brand for context.
