  • Page 48: Initial Visual Inspection

    INSTALLATION WARNING Initial visual inspection After unpacking the instrument, inspect the shipping container and its cushioning material for signs of stress or damage. If there is damage, retain the packing material for examination by the carrier in the event that a claim is made. Examine the instrument for signs of damage; do not connect the instrument to a supply when damage is present, as internal electrical damage could result in a shock if the instrument is turned on.
  • Page 49 In the event that a molded plug has to be removed from a lead, it must be disposed of immediately. A plug with bare flexible cords is hazardous if it is engaged in a live socket outlet. Power cords with the following terminations are available from Aeroflex. Please check with your local sales office for availability.

  • Page 50: Connecting To Supply

    INSTALLATION Connecting to supply The instrument is a Safety Class 1 product and therefore must be earthed. Use the supplied power cord or an appropriate replacement. Make sure that the instrument is plugged into an outlet socket with a protective earth contact. Ensure that the AC supply is correctly connected to the line power receptacle.

  • Page 401 REMOTE OPERATION STATUS COMMANDS STATus:<StatReg>:CONDition? Description: Reads the contents of the status register. Parameters: None. Response: <NR1> Status register contents. STATus:<StatReg>:ENABle Description: Sets the enable mask, which allows true conditions in the status event register to be reported in the summary bit.

  • Page 402 REMOTE OPERATION STATUS COMMANDS STATus:<StatReg>:NTRansition Description: Sets the negative transition filter in the status register. Setting a bit in the negative transition filter causes a 1 to 0 transition in the corresponding bit of the associated condition register, causing a ‘1’ to be written in the associated bit of the corresponding event register.

  • Page 403: Status Reporting

    REMOTE OPERATION STATUS COMMANDS Status reporting An instrument within a SCPI-based system contains a set of registers that reflect the current state of the instrument and whether a particular event has occurred. It is also sometimes necessary for an instrument to generate an alert if that condition exists or if that event has occurred. The status registers contain information about the condition of the instrument.
  • Page 404 REMOTE OPERATION STATUS COMMANDS Status byte register. This 8−bit register (pages 4-203 and 4-204) is used to represent particular conditions or events in an instrument. The status byte register (defined by IEEE 488.1) is read by using the *STB? command or by serial poll. When read by serial poll, an SRQ (service request) is generated that alerts the controller.

  • Page 405: Reading Status Information

    REMOTE OPERATION STATUS COMMANDS Register structures The operation and questionable register structures consist of condition, event, transition and enable registers. The condition registers continuously monitor the instrument's hardware and firmware status. Bits in a condition register are not latched but are updated in real time (so that they represent the actual state of the instrument at all times) and are read by the above commands.
  • Page 406 REMOTE OPERATION STATUS COMMANDS Determine which register sets, and which of its bits monitors the condition. Determine how that bit reports to the request service (RQS) bit of the status byte (some report directly while others may report indirectly through other register sets:). Send remote commands to enable the bit that monitors the condition and to enable the summary bits that report the condition to the RQS bit.

The <erb> status bit is set when one or more errors are present in the error queue.

An internal AF source generates simultaneous two-tone modulation.
  • Page 421 BRIEF TECHNICAL DESCRIPTION RF board The RF board generates a 0.25 to 4000 MHz RF signal. The signal can be modulated with high dynamic range, wide bandwidth AM, FM or IQ modulation. The RF board is housed within an aluminum ‘clamshell’ box. It is connected to an attenuator and a driver board, where these three components become a plug-in RF module.
  • Page 422 BRIEF TECHNICAL DESCRIPTION Driver board This unit, part of the RF tray, is mounted on the metalwork covering the back of the RF board. Two board-to-board connectors interconnect the driver and RF boards. The driver board takes the conditioned detector voltage from the RF board and controls the output power via its ALC loop, which adjusts the ALC modulator on the RF board.
  • Page 423 BRIEF TECHNICAL DESCRIPTION The RTBB board is fitted in the same position as the ARB board. The boards are exactly the same size and shape and are interchangeable, and both are mounted to the control board in the same way. Host interface The host interface is used to configure the FPGA that generates the real-time modulation and interfaces to the rest of the RTBB board, and to provide control of the FPGA and calibration store.

    OPERATIONAL VERIFICATION TESTING Introduction The test procedures in this chapter enable you to verify that the signal generator is operating correctly, in the shortest possible time, using a minimum of test equipment, and with reasonable confidence. These tests are suitable for use as a goods inwards inspection or for a quick verification of performance after repair.

  • Page 428: Test Procedures

    OPERATIONAL VERIFICATION TESTING Test procedures Each test procedure shows you how to configure the test equipment, followed by a description of how to perform the test, with tables for recording your results. Maximum and minimum limits that all measurements should fall within are indicated, provided that the recommended test equipment has been used and the precautions above adhered to.

  • Page 429: Carrier Frequency Test

    OPERATIONAL VERIFICATION TESTING Carrier frequency test This test checks the signal generator’s frequency locking circuitry. It will confirm correct operation of phase locked loops and dividers. Overall accuracy is determined by the instrument’s internal reference standard. By using the UUT’s reference output as the reference frequency for the frequency counter, the test limits are ±1 count.

  • Page 430: Rf Output Level Tests

    OPERATIONAL VERIFICATION TESTING RF output level tests The RF level control test ensures correct operation of the signal generator’s level control circuitry. The output attenuation test uses the instrument’s built-in diagnostic utility to insert each attenuator pad in turn. This ensures that the pads are enabled correctly and that the pad values are nominally correct.
