The '''Tektronix 7D14''' is a 525 MHz frequency counter plug-in for [[7000-series scopes|7000 series mainframes]]. | The '''Tektronix 7D14''' is a 525 MHz frequency counter plug-in for [[7000-series scopes|7000 series mainframes]]. | ||
It uses the mainframe's readout system to display an eight-digit count on the CRT. | |||
Modes include frequency, frequency ratio and events count using manual or external gate. | |||
When installed in a horizontal compartment, it can count the trigger pickoff from a vertical amplifier unit. This allows simultaneous viewing and counting of a signal in four-bay mainframes. | |||
In a vertical compartment, the trigger signal (i.e. the "shaped" input) can be displayed as the module's Y output. | |||
