Cathode ray tube series#

A nattenuating resistor M ds provided in -the lead 8. Resistor =9 in series-with thevariable resistor- 4 *is used :for setting orfixing' the positive voltage ofthe cathode of thyratronb. The -condenser"l together with variable resistor I and fixed resistor 2 gives the desired time constants for the sawtooth wave which is the output on lead '8 that is connected to the plateof the thyratron 3. The grid 6 of the thyratron 3 in connected to ground. A switch 5 is-provided for short-'circuitingthe resistor t, thus firing the thyratronmanually'whenever de-'- sired for a purpose toflce explained later. They are the load resistors of the thyratron '3 which has 'a variable resistor l its-cathode-circuit. These resistors are fed from any convenient source of positive potential.
