The signal passes unattenuated through Q3 to amplifier U6C. The output at U6B(6) feeds the signal through R33 and 9E-4-2.

    Model 5305B Theory of Operation This occurs for each scan of the display. When the 9E-4-14. In the Channel B mode, for example, the measurement ends, the XFER line enables U4 and new data operation is as follows. Once the sample rate runs down enters the latch with the next clock pulse from U11(4).
  • Page 18 Model 5305B Theory of Operation 9E-4-20. Assume, however, the channel B frequency It is important to remember that the frequency/tuning increases. This causes the negative pulses at U22(1) to voltage (U23 pin 6) is a negative relationship. That is, the arrive a little earlier than before, arriving ahead of the lower the tuning voltage, the higher the frequency.

    Model 5305B Theory of Operation 9E-4-30. 1300 MHz ÷ Circuit 9E-4-27. This puts a step in the loop bandwidth at about 300 Hz input, increasing loop bandwidth drastically above 300 Hz. (Higher loop bandwidth is allowable at higher input 9E-4-31. The A2 board amplifies the Channel A signal and frequencies.) This greatly reduces acquisition time for a 10 then divides it by four before sending it to A1 via J2(9).
