Model 5328A Operation SECTION Il l OPERATIO N (OPERATORS INSTRUCTIONS ) 3-1. INTRODUCTIO N 3-2. This section contains information necessary to understand how to control and use the counter. Specific details and examples are provided for making measurements of frequency, period, period average, time interval and time interval average, and ratio.
Model 5328A Operation Figure 3-1. Measuring Linearity 3-9. PERIOD MEASUREMENT S 3-10. The PERIOD and PERIOD AVG functions allow single period measurement or multiple period averages to be made on input signals into Channel A for frequencies up to 10 MHz.

Model 5328A Operation 3-25. FUNCTION OF CONTROLS, INDICATORS, INPUTS, AND OUTPUTS 3-26. The following paragraphs provide a detailed description of the function of controls, indi- cators, and connectors.
Model 5328A Operation Table 3-1. Arming Status 3-37. Frequency Resolution, N Switch 3-38. The FREQUENCY RESOLUTION, N switch determines the amount of time that the counter’s main gate is open for a particular measurement when the Main Gate FF (refer to Section IV) determines the gate time.

Model 5328A Theory of Operation SECTION I V THEORY OF OPERATIO N 4-1. INTRODUCTIO N 4-2. This section contains a description of the operating principles of the counter in reference to an overall block diagram in this section and to individual block and schematic diagrams in Section Vlll.
Model 5328A Theory of Operation 4-9. INPUT AMPLIFIER AND TRIGGER — essentially conditions the input signal to a form that is compatible with the internal circuitry of the counter. As Figure 4-7 indicates, the output of the amplifier/trigger is a pulse train where each pulse corresponds to one cycle or event of the input signal.
Model 5328A Theory of Operation 4-18. Ratio 4-19. By replacing the time base with a second input of frequency, f 2 ; the same configuration as in Figure 4-2 can be used to measure the ratio f 2 /f. For higher resolution the signal at fre- quency f can be divided in decade steps in a manner identical to multiple period averaging.
Model 5328A Theory of Operation 4-24. Resolution 4-25. The resolution of the measurement is determined by the frequency of the counted clock (e.g., a 10 MHz clock provides 100 ns resolution).
Model 5328A Theory of Operation Figure 4-5, Synchronizer Operation with Time Interval Averaging 4-33. There are occasional situations where time interval averaging cannot be performed on a periodic signal. This problem occurs when the input time interval repetition rate is synchro- nous with the internal clock.
Model 5328A Theory of Operation 4-38. FREQUENCY MEASUREMENT ERROR. The error caused by the ambiguity is in ab- solute terms, ±1 of the accumulated count. For a frequency measurement the signal counted is the input signal of frequency, f in . Thus the relative error is given by: ±1 count error, relative frequency measurement error (2) 4-39.
Model 5328A Theory of Operation 4--47. For time interval measurements, trigger error is generally negligible when compared to the systematic error introduced by the uncertainty in the setting of trigger levels.
Model 5328A Theory of Operation Figure 4-8. Block Diagram 4-8.
Model 5328A Theory of Operation counting decades, output multiplexing logic, and synchronizers to generate precise timing signals for the main gate. The oscillator section contains the input/output logic to accept an external signal via the rear panel or an internal signal from the oven-regulated crystal oscillator.
Model 5328A Theory of Operation 4-64. Display Control 4-65. The display control section on Al Motherboard acts as an interface between the A16 Display board and the other circuits of the counter. 4-66. The outputs of the A16 Display Board FUNCTION and RESOLUTION switches go to the ROM (A1U37).
Model 5328A Theory of Operation 4-77. All measurements performed by the 5328A result in pulses being counted in the DCA. Pulses are admitted to the DCA by way of the Main Gate FF on A4 which is either controlled by a Gate Out signal from the Time Base (A1U19) or held open by the HOPN signal from A1U25.
Model 5328A Theory of Operation 4-87. +15V FAN POWER. The +15V supply is a simple linear regulator using transistor Q7 as the pass transistor. Transistor Q2 provides level shifting and current gain while U3 is used as comparator and gain block. The 5328A cooling fan motor receives power from A20.
Model 5328A Theory of Operation 4-96. Time Base Multiplexer and Main Gate FF 4-97. Time Base Multiplexer U10 select either A, B, or OSC to send the Time Base Input (TBI) signal via pin 8 to the Time Base. This same signal is also sent to U1, the Main Gate FF, as a desynchronizing signal.
Model 5328A Theory of Operation 4-107. REMOTE CONTROLLABLE DIAGRAM DESCRIPTION (PROGRAMMABLE) INPUT BLOCK 4-108. I n the local mode, the A19 Switch Control board generates TTL levels that control the A12 signal conditioning relays. These levels allow front panel control of A and B channel input signal conditioning.
Model 5328A Theory of Operation 4-112 . When the interface receives a data byte, for control of trigger levels, it goes into the DAC control mode. This is a result of the interface receiving a + or - on its input data lines. Once in the DAC control mode, the programming interface latches disregard the information at their input.
Model 5328A Theory of Operation 4-114. The A11 DAC board processes the four serial data bytes, and produces one parallel BCD output. The BCD output provides the information for generating a square wave train by using a series of rate multipliers.
Model 5328A Theory of Operation and the exclusive OR gate U2. Schmitt trigger U4 has approximately 15 mV peak-to-peak hysteresis at its input. Exclusive OR gate U2 is used to select the desired slope of the input waveform. When pin 7 of U2 is held to an ECL high level (SLOPE switch in + position), U2 acts as an inverter.
Model 5328A Theory of Operation 4-133. When the 5328A goes into remote, LEXT goes low. The low, on LEXT, causes the output of A1 Motherboard switch control circuit to go from -0.7 volts to +5 volts. This change, disables front panel switch control on the A16 and the A19 boards.
Model 5328A Theory of Operation Since the condition of the MA and MB lines remains the same, the Channel A DAC receives the clock pulses. On the negative transition of the clock pulse, the + or - is shifted into the A channel DAC shift registers A10U7 and U11.
Model 5328A Theory of Operation 4-155. Averager U4 converts the current pulses supplied via CR10 into a dc output voltage. The averager generates the output voltage proportional to the duty cycle of the input current pulses.
Model 5328A Theory of Operation talk or listen addresses on the data lines (DIO1—DIO8). Addresses are set into each device at the time of system configuration either by switches built into the device or by jumpers on a PC board. While the ATN line is low, all devices must listen to the data lines.
Model 5328A Theory of Operation 4-178. Overall Operation 4-179. The heart of the HP-IB Interface is a 256 state algorithmic state machine (ASM) con- trolled by a 256x16 ROM (U22) as shown in the block diagram. This state machine has two dif- ferent format states determined by the format (F) bit from U22.
Model 5328A Theory of Operation the use of the letter “N” in a decision diamond symbol. ) The preset (jump) is synchronous and only occurs when pin 9 of U14 and U23 is low and when there is a rising edge at pin 2 of U14 and U23. FF U31A synchronizes the reset of the State Counters to occur at the proper time.
Model 5328A Theory of Operation operation of the state control circuit U4 on the motherboard. Diode CR3 ensures that LINH is low to inhibit the counter during the time that LRST is low. 4-197. STROBE ENABLE DECODER. Decoder U13 is a 4- to lo-line decoder used to strobe the various storage latches.
