Model 5304A Theory of Operation S E C T I O N IX D 5304A TIMER/COUNTER S U B S E C T I O N IV THEORY OF OPERATION 9 D - 4 - 1 . INTRODUCTION 9D-4-2. This subsection describes the theory of operation for the 5304A Timer/Counter. Basic operation of gates, certain amplifiers and integrated circuits is found in Section IV of the 5300A portion of the manual. 9D-4-3. To simplify measurement making refer to operating information starting with Paragraph 9D-3-1 for optimum adjustment of various controls.
Model 5304A Theory of Operation the 5300A m a i n f r a m e at A1 Pi(16) is routed through U12C as the F2 signal to control the time base, which clocks the opening and closing of the main gate. 9D-4-15. The positive-going edge of a negative pulse from U17E is the MAX TIME signal. The MAX TIME signal a t A1 Pi(17) triggers a display cycle in the 5300A mainframe. This negative-going pulse can be generated from one of two sources.
Model 5304A Theory of Operation signal from the 5300A A1J 1(18) is gated through Q18, U17F, U9B, and U16B to be counted (except in the .1 fjsec position, where the 10 MHz clock is gated through U12A and U16B). The TIME BASE OUTPUT signal is a 10 MHz clock signal divided down by the time base to allow counting in increments of 1 fjsec, 10 fjsec etc. 9D-4-26. The main gate closes when Channel B "clocks" U15A and a display cycle is initiated by the positive-going edge of the M G F F signal at A1P1(12).

Model 5304 A Maintenance performance checks indicate a malfunction or if instrument operation is suspect, perform the SelfCheck procedures in Table 9D-5-1. For further tests, separate the 5304A from the casting and reconnect to 5300A using Paragraph 9D-5-6 steps a to e as a guide. Operating procedures in Subsection 9D-3 can be used to help understand operation. To test the 5304A, obtain the test equipment listed in Table 5-1 of the 5300A portion of the manual. 9D-5-15.
