7D14
The Tektronix 7D14 is a 525 MHz frequency counter plug-in for 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.
