Page 228 R&S ESU Instrument Functions Analyzer Mode Measurement of Occupied Bandwidth An important characteristics of a modulated signal is its occupied bandwidth. In a radio communications system for instance the occupied bandwidth must be limited to enable distortion-free transmission in adjacent channels. The occupied bandwidth is defined as the bandwidth containing a defined percentage of the total transmitted power.
Page 229 R&S ESU Instrument Functions Analyzer Mode ADJUST REF The ADJUST REF LVL softkey adjusts the reference level of the R&S ESU to the measured total power of the signal. The softkey is activated after the first sweep with the measurement of the occupied bandwidth has been completed and the total power of the signal is thus known.
Page 230 R&S ESU Instrument Functions Analyzer Mode Some of the measurement specifications (e.g. PDC, RCR STD-27B) require mea- surement of the occupied bandwidth using a peak detector. The detector setting of the R&S ESU has to be changed accordingly then. Example Measurement of occupied bandwidth of a PDC signal at 800 MHz, level 0 dBm [PRESET] Set the R&S ESU to the default setting.

Page 414: Structure And Syntax Of The Device Messages
R&S ESU Remote Control – Basics Structure and Syntax of the Device Messages • According to the effect they have on the instrument: Setting commands cause instrument settings such as reset of the instrument or setting the center frequency. Queries cause data to be provided for output on the GPIB, e.g. for identification of the device or polling the marker.
Page 415 R&S ESU Remote Control – Basics Structure and Syntax of the Device Messages The commands used in the following examples are not in every case implemented in the instrument. Common commands Common commands consist of a header preceded by an asterisk "*" and one or several parameters, if any.
Page 416 R&S ESU Remote Control – Basics Structure and Syntax of the Device Messages Some key words occur in several levels within one command system. Their effect depends on the structure of the command, that is to say, at which position in the header of a command they are inserted.

Page 592 R&S ESU Remote Control – Description of Commands SENSe Subsystem 6.16.1 SENSe:AVERage Subsystem The SENSe:AVERage subsystem calculates the average of the acquired data. A new test result is obtained from several successive measurements. There are two types of average calculation: logarithmic and linear. In case of logarithmic average calcu- lation (denoted with VIDeo), the average value of the measured logarithmic power is calculated and in case of linear average calculation, the linear power is averaged before the logarithm is applied.
Page 593 R&S ESU Remote Control – Description of Commands SENSe Subsystem [SENSe<1|2>:]AVERage:TYPE VIDeo | LINear This command selects the type of average function.

Page 794 R&S ESU Remote Control – Programming Examples Basic Programming Steps for the VISA Interface 7.2.1.3 Waiting Without Blocking the Keyboard and Mouse A frequent problem with remote control programs using Visual Basic is to insert wait- ing times without blocking the keyboard and the mouse. If the program is to respond to user inputs also during a waiting time, control over the program events during this time must be returned to the operating system.
