    Tektronix 7D15 225 MHz Universal Counter/Timer Plug-In for the Tektronix 7000 Series oscilloscope mainframes having CRT readout. Its many features include:
  • Frequency Mode: DC to 225MHz, resolution is 0.1Hz
  • Period and Multi-Period Mode: 10 ns to 10E+05 s with selected averaging of 1 to 1000 events in decade steps, 10 ps max resolution
  • Time Interval (TI) and TI Average Mode: 6 ns to 10 s with selected averaging times of 1 to 1000 in decade steps, 0.1 ns resolution
  • Frequency Ratio, CH B/Ext. Clock: 10E-07 to 10E+04
  • Manual Stop Watch: 0 to 10E+05 s
  • Totalize, CH B: 0 to 10E+08 counts
    The 7D15 can be completely controlled by the oscilloscope's delayed gate. Arming inputs are provided for each channel. By using the delayed B gate to control the start and stop count points, measurements can be made between any two points on the CRT display. The 7D15 offers all the measurement capabilities of a Universal Counter/Timer, such as time interval, period, period and time interval averaging, frequency, frequency ratio, totalize, and manual stop watch.

    The 7D15 may be used in vertical or horizontal compartments of 7000-Series mainframes. Legend and averaging information appear at the bottom of the CRT display.
