The Keithley Instruments CTM-PER Continuous Period Counter is a PC-computer accessory board for monitoring timing changes in an on-going lTL signal. The board measures consecutive periods of a lTL signal and makes the results available for review, analysis, etc. For example, the results can be presented to the PC monitor in an array of consecutive measurements.

TIl signal frequencies may range from 0 (DC) to 80 KHz. The 80KHz upper frequency limit actually depends on frequency limits of the computer. In some computers, the upper frequency limit will be no more than 20 KHz.)

Typical CTM-PER applications include monitoring a Doppler signal and measuring output intervals of a rotating sensor. BNC connectors labeled SIGNAL and GATE are available at the board's rear plate. GATE can be programmed with selective polarity and used to enable measurements. SIGNAL can measure the timing of positive, negative, or both edges.
