The Tektronix 202 family encompasses three distinct product lines: a mobile oscilloscope cart platform, a portable digital storage oscilloscope, and a current probe. Each variant addresses specific measurement requirements, from laboratory bench mobility to field-portable diagnostics and direct current sensing.

– Key Features
202 Cart Series
Multiple configurations support different measurement workflows. The standard 202 provides a stable platform with storage capability. The 202-2 variant adds a dedicated carrier for two 500-series plugin modules, enabling multi-function test setups. Tilt-lock mechanisms on selected units prevent drift during operation.
T202 Handheld Unit
Battery-powered operation enables measurements in field environments without external power. The 128×128 LCD display integrates Auto-set, Save/Recall Setup, Cursor, and On-Screen Readout functions. Compact form factor fits standard toolboxes, glove compartments, and briefcases. Internal architecture includes microcontroller-based signal processing with dedicated voltage reference and proprietary measurement ICs.
TCP202 Current Probe
Direct TekProbe interface eliminates adapter requirements for TDS oscilloscope integration. 50 MHz bandwidth supports both DC transient and AC ripple analysis in power conversion and motor drive applications.
– Compatibility & Integration
The 202 and 202-1 carts accept standard Tektronix 500-series oscilloscopes. The 202-1 mod 52 accommodates the Tektronix 519 with increased tray width. The T202 operates with P6115 probes. The TCP202 connects directly to Tektronix TDS oscilloscopes via the TekProbe interface for unified current and voltage measurement.
