HISTO12 is an interspike interval plotting routine. The program uses an adiustable threshold to discriminate against baseline noise and will eliminate spikes shorter than 500 us or longer than 2.1 ms. A limit to the number of spikes counted may be selected. Printed output consists of sampling diagnostics, total spikes counted, the average input frequency, total time in sampling, and number of spikes not appearing in the display. The display in either scattergram or histogram mode may be expanded horizontally defining intervals of 0.0 to 0.2 to 0.0 to 1.6 seconds. Vertical scaling is accomplished by addition, subtraction or by multiplication, division. Complete operating instructions type out upon program startup.
