The 5264A Preset Unit extends the versatility of the 5245L Electronic Counter’s time base, and the counter retains its basic functions and measurement range.

The 5264A makes possible:

1. Frequency measurements for N units of time (N x Freq) .

2. Measurement of time for N events to occur ( N x Period).

3. Ratio Bnd normalized ratio measurements ( N x Ratio),

4. Counting N events (Preset).

5. Division of input frequency by N (f/N)

In these modes N may be any integer‘between 1 and 100,000. Decade dividers in the preset unit control the counter gate.
