The Cal Test Electronics CT2841A is a general-purpose 5 mm passive voltage oscilloscope probe with switchable 1x/10x attenuation and a 350 MHz bandwidth in the 10x position. It belongs to Cal Test's HighPerformance family of passive voltage probes, designed as quality replacement probes compatible with a wide range of oscilloscope makes and models.

Per the datasheet, the CT2841A is positioned as a general-purpose replacement probe for oscilloscopes across makes and models. Its switchable 2-position design lets engineers move between unity-gain (1x) viewing of low-amplitude signals and 10x attenuation for higher-bandwidth, lower-loading measurement on the same probe without changing accessories.
