The OG-8 is a very unusual high speed counting tube. The tube is a single guide, unidirectional design with a carbolite octal base. Argon filled. The tube has 20 bent cathodes under a heavy shade ring, five of which are brought out to individual pins on the base. The tube's rated counting speed is 100Khz and the fill gas in unknown, though it appears to contain a mix of hydrogen and other gases. The OG-8's anode voltage is much higher than other dekatrons: the tube must be driven at nearly 600 volts to achieve ionization. Normal dekatron driver circuits have trouble spinning the OG-8, and the home experimenter should not expect a stock spinner design to work reliably with this tube. OG-8 Decatrons-pulse counting with the direction of the cathode for use in counting and computing devices for frequency division. It is used in computer engineering, instrumentation and various counting device electronic equipment. Light color - blue. Members cold cathodes. Work in any position. Indication is made through the dome of the container. Registration - glass, with cap (RSH5-1). Basic data The conversion factor of 10 Power supply voltage> 400 W Firing voltage <480 Discharge sustaining voltage 255-295 In The bias voltage to 36-44 in podkatodah The amplitude of the voltage pulse discharge in 75-125 Ignition delay time <5 Operating current of 1.1-1.3 mA These control pulses: counting speed 000 Hz * 0.01-100 The amplitude of the pulse 80-110 pulse duration> 3 ms front duration 0.3-1 ms Reset pulse duration> 10 ms Working hours> 500 hours Guaranteed shelf life of 8 years The maximum allowable parameters The output voltage on the cathodes 7 Cathode load resistance <7.5 ohms Operating temperature range -60 ... +70 ° C * At 1 Hz decatrons not allowed to work more than 2 hours, provided the subsequent operation at frequencies of 50 Hz and above for an hour, the total standing time of discharge does not exceed 50 hours."
