The 5233L is a six digit solid-state counter capable of a maximum counting rate somewhat greater than 2 MHz. Frequency/period/ratio is displayed on six rectangular nixie tubes. It is capable of measuring frequency up to 2 MHz, counting random or periodic pulses, determining ratios and measuring periods or time intervals. Inputs may be DC or AC coupled; maximum sensitivity is 0.1 V for sinusoidal inputs and 1 V with a minimum duration of 0.2 µs for pulse inputs, max 100 V

It is housed in a Clement Cabinet 16-3/4“ W x 3-15/32” H x 11-1/4“ D (425 x 86 x 285 mm)
