Abstract:
A programmable timing unit (PTU) has been designed and constructed having 1 ns resolution and a generalized matrix-based architecture. Automated measurement and calibration of commercially available programmable delay lines achieve the 1 ns resolution. The matrix architecture allows generalized flexibility in establishing the connections between timing circuits called event markers and output functions that control equipment external to the PTU. The microprocessor-based PTU communicates with a PC through a standard RS-232C serial interface. The PC contains software developed to control specific timing sequences produced by the PTU for control of experimental apparatus. While the PTU was developed for use in an electron paramagnetic resonance laboratory, the architecture is extremely generalized and use in other applications would require only the development of specific application software. The software developed so far has been done in Microsoft Visual BASIC, but other software tools could be used without modification of the PTU hardware.
