The '''Tektronix 7B85''' is a 400 MHz delaying timebase for [[7000-series scopes]], typically the 7800 Series, e.g. [[7844]]. | The '''Tektronix 7B85''' is a 400 MHz delaying timebase for [[7000-series scopes]], typically the 7800 Series, e.g. [[7844]]. | ||
The digital delay differentiates the 7B85 from the [[7B80]]. The [[7B87]] is similar to the 7B85 but provides | The delay function (with digital delay and delta time read-out capability) differentiates the 7B85 from the otherwise similar [[7B80]]. | ||

The [[7B85]]/[[7B80]] combination was introduced in 1976 to replace the 200 MHz [[7B71]]/[[7B70]] that had no delay read-out. | |||
