The chapter is organized as follows: •...
  • Page 408 ® Special Terms and Notation R&S Combined measurements To limit the number of remote control command and their parameters, scalar quantities of the same measurement object are always measured together and returned in lists. Parameters Many commands are supplemented by a parameter or a list of parameters. Parameters either provide alternative options (setting a or setting b or setting c ..., see special character "|"), or they form a list separated by commas (setting x,y).
  • Page 409 ® R&S Special Terms and Notation Lists of commands The Command column of the table contains all remote control commands ar- Command: ranged according to their function (configurations or measurement objects). Within a section, the commands are listed in alphabetical order. The Parameter column lists the parameters of the commands.

  • Page 410: Common Commands

    ® Common Commands R&S Common Commands The common commands are taken from the IEEE 488.2 (IEC 625-2) standard. These commands have the same effect on different devices. The headers of these commands consist of "*" followed by three letters. Many common commands are related to the status reporting system which is described in detail in Chapter 5.
  • Page 411 ® R&S Common Commands *IST? INDIVIDUAL STATUS QUERY returns the contents of the IST flag in decimal form (0 | 1). The IST- flag is the status bit which is sent during a parallel poll (see chapter 5). *OPC OPERATION COMPLETE sets bit 0 in the event status register when all preceding commands have been executed.

    ® Hardware Interfaces R&S Hardware Interfaces The following sections give a description of the instrument’s front and rear panel connectors with their technical data. GPIB Bus Interface The instrument is equipped with a GPIB bus (IEC/IEEE-bus) connection. The interface connector labeled IEEE 488 / IEC 625 is located on the rear panel of the instrument.

  • Page 727: Bus Lines

    ® R&S Hardware Interfaces Bus Lines 1. Data bus with 8 lines D0 to D7 The transmission is bit-parallel and byte-serial in the ASCII/ISO code. D0 is the least significant bit, D7 the most significant bit. 2. Control bus with 5 lines IFC (Interface Clear), active LOW resets the interfaces of the instruments connected to the default setting.

  • Page 728: Interface Messages

    ® Hardware Interfaces R&S Interface Messages Interface messages are transmitted to the instrument on the data lines, with the attention line being active (LOW). They serve to communicate between controller and instrument. Universal Commands Universal commands are encoded in the range 10 through 1F hex. They are effective for all instruments connected to the bus without pervious addressing.
