GEMAC CAN-Bus Tester GT3, included tablet, measuring head, case with accessories included all licenses for 36 months
*As part of the product launch, we are offering the device at an attractive introductory rate for a limited time. If you place your order by December 31, 2026, you will receive the GT3 with all licenses for 36 months.
As a completely redesigned piece of hardware and software, the CBT GT3 addresses the physical challenges of higher CAN FD baud rates up to 5 Mbit/s with new measured values such as signal quality FD, setup/hold time, and signal-to-noise ratio in dominant and recessive phases. The robust measuring head with M12 connection and external ground option minimizes interference, while advanced logical analyses (CANopen, SAE J1939, protocol monitor) provide a holistic view of physical, logical, and functional levels. With up to 8 hours of operating time, IP20 protection, and PC software compatibility, the GT3 sets new standards for mobile and stationary CAN diagnostics.
The CAN Bus Tester GT3 embodies a consistent further development of proven principles from earlier GEMAC models such as the CAN Bus Tester 2 and CANtouch, combined with groundbreaking innovations for the requirements of modern CAN and CAN FD systems. While previous devices focused on robust physical bus analysis, the GT3 takes this philosophy to a new level: a battery-powered tablet diagnostic device with a remote measuring head enables precise measurements without disruptive stub cables – ideal for harsh field applications and precise development work in CAN Classic and CAN-FD.
Familiar elements such as oscilloscope views with color coding of the differential signal and classic level measurements (CANH/CANL) ensure a smooth transition for existing users
| Physical Measurements | |
| Bus analysis | Monitors bus status, error telegrams, voltages, common mode, and CAN levels in real time—for reliable network diagnostics. |
| Node details | Up to 30 values per participant (Classic/FD) – bus load, error frames, voltages, setup/hold times, signal quality, and bit asymmetry. Graphical oscilloscope view with decoding for precise troubleshooting. |
| logger | Time-series recording of all measured values – ideal for detailed fault analysis in the network. |
| wiring | Quick 4-step test for reliable verification of bus wiring – prevents costly connection errors from the outset. |
| Logical Measurements | |
