The '''Tektronix 7D15''' is a 225 MHz frequency counter plug-in for [[7000-series scopes]]. | The '''Tektronix 7D15''' is a 225 MHz frequency counter plug-in for [[7000-series scopes]], [[introduced in 1972|introduced in November 1972]]. | ||
The 7D15 is optimized for timing measurements, having a 100 MHz oscillator and interval measurement averaging capability. It has two inputs and can measure frequency, period or time difference. | |||
The front panel uses [[SMB connector]]s for arming, clock in/out and reset signals. The arming input for channel A is active-high whereas that for channel B is active-low. When one or both are connected to the scope's delayed gate output, the delayed timebase can be used to select the part of the signal to be counted, e.g. for burst or A-B interval measurements. With this connection, the arming interval is directly visible as the intensified trace in the "A intensified by B" display mode. | The front panel uses [[SMB connector]]s for arming, clock in/out and reset signals.
