MHz and 10 MHz are derived from the TTL level signals by passing the square waves through elliptic low pass filters The filter outputs are then coupled to emitter follower stages to provide low impedance distribution points for each frequency Each filter is 3 dB down just above the fundamental frequency 1 MHz 5 MHz or 10 MHZ and is more than 80 dB down at the 3rd harmonic OUTPUT DRIVER AMPLIFIERS One of the filter outputs is routed to J15 and coupled to the base of Q14 through C93 The bases of 014 and Q13 are biased by R151 R153 and R155 from the 15V supply The base of Q13 is at approximately 10VDC and the base of Q14 at approximately 12 5V The amplitude of the sine wave input to Q14 is 600 650 mV This signal is amplified by Q14 and applied through R154 to the emitter of cascade transistor Q13 The signal is further amplified by Q13 and applied across the primary of output transformer T1 and R152 The signal at the secondary is coupled to the CHANNEL 1 output connector through C95 at an amplitude of approximately 1 0V RMS CHANNEL 2 and CHANNEL 3 output amplifiers are identical to CHANNEL 1 OUTPUT ERROR DETECTION The signal at the primary of T1 is coupled through C138 to a voltage doubling detector consisting of R158 CR5 C97 and R194 A positive DC voltage appears across C97 and R194 when an output signal is present at the primary of T1 The detected voltage is compared with a reference voltage VR of 4 5 Artis
