– Key Features
The probe includes interchangeable tip assemblies—spring, rigid, and pincher tips—plus five IC cap types supporting 0.5 mm to 1.27 mm pitches for direct component access. Ground connectivity options include a lead, spring, and blade configuration. Copper pads enable direct IC connection for ultra-low parasitic measurements.
A two-footer probe positioner facilitates hands-free, multi-channel setups. Four marker tip colors aid channel identification across complex test benches.
Compliance with IEC61010-031 ensures measurement category ratings. When combined with accessories of different categories, the lowest applicable category governs overall voltage rating.
– Typical Applications
IC and PCB troubleshooting in high-speed digital and analog circuits. Point-of-care signal monitoring on boards with tight component spacing.
– Compatibility & Integration
Automated probe ID recognition streamlines oscilloscope setup. Compatible across Yokogawa DLM2000, DLM4000, DL6000, and DLM6000 series. Operates 0 °C to 50 °C; rated to 2000 m altitude.
