  • Page 63 This command is useful for clearing only a selected instrument instead of all devices simultaneously. The Model 6010 will return to the default conditions listed in Table 4-4 when responding to an SDC command. To transmit the SDC command, the controller must perform the following steps: 1.
  • Page 64 Generally, these commands are sent as one or more ASCII characters that tell the device to perform a specific function. For example, F0 is sent to the Model 6010 to place the instrument in the FREQ A mode. The IEEE-488 bus treats device- dependent commands as data in that ATN is high (false) when the commands are transmitted.
  • Page 65 IEEE-488 Operation 4-9. DEVICE-DEPENDENT COMMAND PROGRAMMING IEEE-488 device-dependent commands are sent to the Model 6010 to control various operating conditions such as display modify, operating mode, output and parameter insertion.

  • Page 71 The v peak measurement rate command controls the rate of which the instrument will perform the v peak measurements at the input connector of the Model 6010. The fast rate is normally used where the frequency to be measured is above 100 Hz. The slow rate is used when performing measurements below 100 Hz.
  • Page 72 4-9-17. Triggering (T) The "T" and GET commands are used to trigger the Model 6010 over the IEEE bus. Triggering arms a measurement cycle. In the continuous mode, the Model 6010 is always armed. In the hold mode (S0), a separate trigger stimulus is required to arm each measurement cycle.
  • Page 73 SRQ Mask: In order to facilitate SRQ programming, the Model 6010 uses an internal mask to generate the SRQ. When a particular mask bit is set, the Model 6010 will send a SRQ when those conditions occur. Bits within the mask can be controlled by sending the ASCII letter "Q"...

  • Page 100 As an example, a conventional counter measuring 1 KHz with a gate time of 1 second will display a resolution of 1 Hz where Model 6010 with the same gate time will always display a minimum of seven digits of resolution (eight digits with option 1).
  • Page 101 Theory of Operation Synchronizer #2 generates the synchronized gate time 2 (SGT 2) from SGT 1. SGT 2 now has a period with an exact integer multiple of pulses from the reference clock signal. Counter N2 totalizes the number of reference clock pulses (CLK 2).
  • Page 103 N1 x T where; T = the period of the reference clock (CLK) A simplified block diagram of the complete Model 6010 is given in Figure 5-3. The input signal is applied through the input amplifiers to switching circuits which in turn routes the signals to the correct counting circuits.
  • Page 104 Channel A and B. Input Protection: Front panel input conditioning are capable of handling signals within the specified dynamic range of the Model 6010. Protection of the input circuit from over-voltage signals (up to the specified limits) are done by R4, clipping diodes within U10, C8, R7, CR 2 and Q2.
  • Page 105 Theory of Operation 6-3-3. 10MHz Standard Reference Oscillator The reference oscillator circuit comprises an hybrid oscillator U57, buffers U56 and voltage regulator U55. C124, C125 and C126 adjust the oscillator frequency to a known reference. C124 is a coarse adjust and C126 is a fine adjustment.
  • Page 106 Theory of Operation Control: The control circuit consists of U15, U14 and U13. Information from the CPU is sent in a serial form to the control ics which in term convert the serial information to a parallel format. The parallel outputs of these ICs are being used to control the signal selectors, and the signal routing to the various sections within the measuring logic section.

The gate identifier circuit also serves as a time stretcher of gate signals with very small periods. The gate identifier consists of U26a, U26c, U31d, R158 and C86. N1 Counter Chain: The N1 counter chain comprises U30b, U31c, U27a, U23a, U46a and U44 and their associated components.

IEEE Interface The Model 6010 has a built in IEEE-488 interface that allows the instrument to be controlled through the system controller. Commands may be given over the bus and data may be requested from the instrument as well.
  • Page 116 Most equipment is subject to at least a small amount of drift when it is first turned on. To ensure long-term calibration accuracy, turn on the power to the Model 6010 and allow it to warm-up for at least 30 minutes before beginning the adjustment procedure. 7-2-3. Recommended Test Equipment Recommended test equipment for calibration is listed in Table 5-2.

  • Page 122 7-4-1. Recommended Test Equipment The success or failure in troubleshooting a complex piece of equipment like the Model 6010 depends not only on the skill of the technician, but also relies heavily on accurate, reliable test equipment. Table 6-2 lists the recommended test equipment for a complete troubleshooting and adjustment of the Model 6010.
  • Page 123 7-5. TROUBLESHOOTING PROCEDURE 7-5-1. Power Supply Checks It is highly suggested that the first step in troubleshooting the Model 6010, as well as any similar equipment, would be to check the power supply. If the various supply voltages within the instrument are not within the required limits, troubleshooting the remaining circuits can be very difficult.

Standard 5PPM Reference Oscillator Checks The reference oscillator supplies a precise signal to the measurement logic section of the Model 6010. Without this clock the instrument will operate erratically. Verify that a 10 MHz TTL level signal is present at U57 pin 5, U56 pin 6, 3 and 8 and at the CLOCK output rear panel connector.
