  • Page 48: Switch-On Procedure

    Manual Control 2.1.3 Switch-On Procedure Upon switch-on a program is triggered for testing and initialization of the instrument. The program tests the hardware configuration and initializes the individual modules. Set parameters of the remote-control interface are displayed in bottom half of the screen. In the case of a fault, an error message is displayed with information on the defective unit.

    Manual Control 2.1.4 General Information 2.1.4.1 Menu Operation Operating menus are in the form of pull-down menus. Subsequently opened menus do not cover up already opened menus so that the complete path is visible until its termination. Selection within a menu or submenu is made by means of the cursor keys. The selected field is either marked by a dark background or an arrow.
  • Page 50 Manual Control Fig. 2-5 Menu selection Pressing the BACK key causes a return to the previous menu level. Pressing the HOME key causes a return to the initial menu irrespective of how many submenus are open. Further selection menus can be called up directly by pressing the MEM key, SETUP/INFO and STATUS (F2) provided the operator is not in an EDIT window.
  • Page 51: Calibration

    Manual Control 2.1.4.2 Calibration SFQ features several internal calibrations in the SETUP-HARDWARE-CALIBRATING menu (see 2.2.13.1.1). In addition to ALL, VCO SYNTHESIS, RF LEVEL, LEARN TABLE and NOISE ALL, calibration of I/Q modulator is possible in this menu: I/Q Modulator: This calibration is especially important since it serves for optimizing carrier leakage, I/Q imbalance and phase error.
  • Page 52 Manual Control C/N calibration: An internal calibration is provided with optional Noise Generator SFQ-B5 model 03. It can be carried out with the F3 key in the MODULATION-NOISE menu for the selected modulation mode. Note: Calibration becomes necessary if the ambient temperature changes by more than 5°C.

Tables may be prepared by the user in the SETUP menu and assigned a name.
  • Page 56: Rf Frequency (With Vsb Modulation)

    Fig. 2.2-3 RF FREQUENCY (with VSB modulation) In contrast to all other types of modulation of SFQ, there are up to three different ways of entering the output frequency of the spectrum in the ATSC modulation: "PILOT FREQUENCY": The pilot frequency in the output spectrum determines the frequency of the output spectrum.
  • Page 57 Menu Operation PILOT → → → → In this menu the output pilot frequency of the ATSC spectrum can be set. The unit of the set frequency is always [MHz]. In this case, the pilot frequency does not depend on the symbol rate of the modulator since it corresponds to the unmodulated carrier signal.
  • Page 58 (calculated) deviates from the entered nominal frequency. FREQUENCY SHIFT→ → → → : In this menu, the output frequency of SFQ can be assigned a shift. This modifies the frequency at the SFQ output connector. The frequency shift is always set in [MHz].
  • Page 59 Menu Operation Fig. 2.2-5 CHANNEL CHANNEL→ → → → The frequency can be set indirectly by means of a channel table. In this case the channel number is entered directly or the channels are selected one after the other with the aid of the cursor keys. The channels of the selected table are used.

Unlike the transmission standards already in use in the other parts of the world, the television, radio and data services are to be covered by one standard. The Japanese broadcasting standard ISDB-T (Terrestrial Integrated Services Digital Broadcasting) was established, in which these services can be transmitted separately in a large number of combinations.

The goal of the SCPI Consortium is to standardize device-specific commands to a large extent.

    No prefix is allowed for the units DBM and DB. For voltages, additional logarithmic units in the form of dB<prefix>V are supported. As a rule, numeric values are inadmissible for queries of the SFQ. This does not apply however to the special numeric values described below.

    Remote Control 3.5.6 Overview of Syntax Elements The following list provides an overview of the syntax elements. The colon separates the keywords of a command. In a command line, the colon following a semicolon identifies the highest command level. The semicolon separates two commands in a command line. It does not change the path. The comman separates several parameters of a command.

  • Page 413: Command Identification

    Remote Control 3.7.2 Command Identification The command identification analyzes the data received from the input unit, proceeding in the order in which the data are received. Only a DCL is given priority but a GET (Group Execute Trigger) for instance is processed only after the previously received commands are executed. Any identified command is forwarded immediately to the data set but not immediately executed.
  • Page 414: Output Unit

    Remote Control 3.7.5 Output Unit The output unit collects the information requested by the controller from the data set management. It processes the information in line with SCPI rules and makes it available to the output buffer. The output buffer has a capacity of 1024 characters. If the requested information is longer, it will be made available in portions in a way that is not noticeable to the controller.
  • Page 415: Status Reporting System

    Remote Control Status Reporting System The status reporting system (see Fig. 3.8-1) stores all information on the current operating status of the device, eg that an AUTORANGE is being performed at present, and on errors occurred. The information is stored in the status registers and in the error queue. The status registers and the error queue can be queried via the IEC/IEEE bus.
  • Page 416 Remote Control CONDition register The CONDition register is directly written by the hardware or the summary bit of the next lower register. Its content reflects the current device status. This register can only be read but neither written nor cleared. Reading the register does not change its content.

    Remote Control 3.8.3 Description of Status Registers 3.8.3.1 Status Byte (STB) and Service Request Enable Register (SRE) The Status Byte Register is already defined in IEEE 488.2. Since it collects all the information of the other lower-order registers it gives a rough overview on the device status. Its function corresponds to that of the CONDition register of an SCPI register and assumes the highest level in the SCPI hierarchy.

    Remote Control 3.8.3.2 IST Flag and Parallel Poll Enable Register (PPE) Similar to the SRQ, the IST flag combines the complete status information in a single bit. It can be queried by a parallel poll (see section 3.8.4.3) or by the query *IST?. The Parallel Poll Enable Register (PPE) determines which bits of the STB affect the IST flag.

    Remote Control 3.8.3.4 STATus:OPERation Register This register contains information in the CONDition register on operations currently performed by the device or in the EVENt register on operations performed by the device since the last readout. It can be set by the commands STATus:OPERation:CONDition or STATus:OPERation[:EVENt] and read by the queries STATus:OPERation:CONDition? or STATus:OPERation[:EVENt]?.
  • Page 421: Use Of Status Reporting Systems

    Remote Control 3.8.4 Use of Status Reporting Systems For an efficient use of the status reporting system, the information contained therein has to be transferred to the controller and further processed. There are various methods which are described in the following. Detailed program examples are given in Appendix D3 3.8.4.1 Service Request, Use of Hierarchical Structure Under certain conditions, the device may send a service request (SRQ) to the controller.
