    MT8801C has been allowed to dry out sufficiently. Fan clearance: To suppress any internal temperature increase, the MT8801C has a fan on the rear panel as shown in the diagram below. Leave a gap of at least 10 cm between the rear panel and the wall, nearby equipment or obstructions so that fan ventilation is not blocked.
  • Page 34: Safety Measures

    Safety measures for power supply WARNING I Before power-on: • Protective grounding The MT8801C must be connected to ground. If the power is turned on without taking this countermeasure, there is a risk of receiving an accidental electric shock. • Power supply voltage In addition, it is essential to check the power supply volt- age.
  • Page 35: Maximum Power To Connector

  • Page 36: Preparations Before Power-On

    2.3 Preparations before Power-on Preparations before Power-on The MT8801C operates normally when connected to 100 to 120 Vac, 47.5 to 63 Hz, or 200 to 240 Vac, 47.5 to 63 Hz AC power supply via the power inlet. To prevent the following problems, take the necessary procedures described on the following pages before power is supplied.
  • Page 37: Protective Grounding

    The power supply polarity of the 3-pole (grounded, 2-pole type) matches that of the 3-core power cord plug. Therefore, the MT8801C is connected to ground potential when the power cord is connected to the plug. As a result, it is not necessary to connect the FG terminal to ground.

  • Page 39: Replacing Fuse

    Section 2 Preparations Before Use 2.3.2 Replacing fuse The MT8801C with standard accessories has two spare fuses (T6.3A250V). Use these fuses to replace the blown fuses. If the fuses must be replaced, locate and rem- edy the cause before replacing the blown fuses.
  • Page 40 Remove the fuse from the fuse cap and replace it with a spare fuse*. Return the fuse cap with the fuse to the fuse holder, then fasten it by turning it clockwise with the screwdriver. * Contact the Anritsu service department for fuses by specifying the model name, order number, name, and quantity.

Calibration Requirements .......... Equipment Required for Calibration ......Calibration ..............7.3.1 Calibrating the reference crystal oscillator ..
  • Page 273 Calibration should be performed periodically even if the MT8801C is operating nor- mally. We recommend that the MT8801C be calibrated once or twice a year. Contact the Service Department of Anritsu Corporation if the MT8801C fails to meet the specifications during calibration. Equipment Required for Calibration The table below shows the equipment required to calibrate each item.
  • Page 274 7.3 Calibration Calibration Do not start the performance tests until the MT8801C and measuring instruments have warmed up for at least 24 hours and they have stabilized completely. To obtain the best measurement accuracy, do the calibration at room temperature. Keep AC power voltage fluctuations, noise, vibration, dust, humidity, and any other factors which can affect results to a minimum.
  • Page 275 Apply the standard frequency signal to the external reference input of the frequency counter. Move to the RX Measure screen in the Analog Tester mode on the MT8801C. Set the frequency of the signal generator of the MT8801C to 1 000.000 000 MHz, the level to –28 dBm, and the modulation to off.

  • Page 384 Section 5 Status Messages This section describes MT8801C status messages, their data structure and models, and explains the techniques for synchronizing the controller and the MT8801C. To obtain more detailed status information, the IEEE488.2 standard has more com- mon commands and common queries than the IEEE488.1 standard.
  • Page 385 The following pages explain the status summary message and structure of status data that constitutes the status summary message bits, as well as techniques for synchro- nizing the MT8801C and controller, which use these status messages. These functions are used by an external controller with the GPIB interface bus.

  • Page 387 Section 5 Status Messages The IEEE488.1 status byte is used in the status model. This status byte is composed of seven summary message bits given from the status data structure. To create the sum- mary message bits, there are two models for the data structure: the register model and the queue model.
  • Page 388: Status Byte (Stb) Register

    5.2 Status Byte (STB) Register Status Byte (STB) Register The STB register consists of device STB and RQS (or MSS) messages. The IEEE488.1 standard defines the method of reporting STB and RQS messages, but not the setting and clearing of protocols or the meaning of STB. The IEEE488.2 standard defines the device status summary message and the Master Summary Status (MSS) which is sent to bit 6 together with STB in response to an *STB? common query.
  • Page 389: Device-Dependent Summary Messages

    As shown below, the MT8801C does not use bits 0, 1 and 7. As it uses bits 2 and 3 as the summary bit of the status register, it has 3 register model types (where 2 types are extended) and one queue model type (with no extension).
  • Page 390: Reading And Clearing The Stb Register

    5.2 Status Byte (STB) Register 5.2.3 Reading and clearing the STB register Serial poll or the *STB? common query are used to read the contents of the STB register. STB messages conforming to IEEE488.1 can be read by either method, but the value sent to bit 6 (position) is different for each message.
  • Page 391 Section 5 Status Messages (3) Definition of MSS (Master Summary Status) MSS indicates that there is at least one cause for a service request. The MSS message is represented by bit 6 in a device response to the *STB? query, but it is not generated response to serial poll.
  • Page 392: Enabling The Service Request (Srq)

    5.3 Enabling the Service Request (SRQ) Enabling the Service Request (SRQ) All types of summary messages in the STB register can be enabled or disabled for service requests (SRE) by using the program-controlling service request (SRQ) en- able operation. The service request enable (SRE) register controls the generation of SRQ in bits 0 to 7 as shown in the diagram below.

  • Page 394 This bit is produced regardless of whether a device is in remote or User Request (URQ) local mode. It is not used for the MT8801C so, it is always set to 0. An illegal program message, a misspelt command or a GET Command Error (CME) command within a program is received.

    Notes on Fetching the Waveform Data (1) Fetching screen • The waveform data to be fetched must be displayed on the MT8801C screen. • Check that the measurement terminates before fetching the waveform data. If Continuous measurement mode is set or measurement does not terminate, the correct data cannot be fetched.
