Tektronix 7D14

The Tektronix 7D14 is a Digital Counter Plug-In.

The 7D14 is a directly gated unit that is designed to use in all 7000-Series Oscilloscope mainframes, but not with those that don't have CRT READOUT. It will function in any plug-in compartment. It has three modes of operation including frequency ratio (A / B) 0 to 10E+05:1, frequency 0 to 525MHz, and totalize 0 to 10E+08. The 7D14 counts directly to 525MHz. The gated approach makes possible "single event" counting which is often very desirable in rapid burst measurements.
