30. This information is stored in status registers and in an error queue The status registers and the error queue can be queried via the IEC IEEE bus The information is of a hierarchical structure The highest level is formed by the status byte STB register defined in IEEE 488 2 and the associated service request enable SRE mask register The STB register receives information from the standard event status register ESR which is also defined in IEEE 488 2 with the associated standard event status enable ESE mask register and from the registers STATus OPERation and STATus QUEStionable which are defined by SCPI and contain detailed infor mation on the instrument The status reporting system further comprises the IST flag Individual STatus with the parallel poll enable PPE register allocated to it The IST flag like the SRQ combines the entire instrument state in a single bit The function fulfilled by the PPE register for the IST flag corresponds to that fulfilled by the SRE for the service request The output buffer contains the messages the instrument returns to the controller The output buffer is not part of the status reporting system but determines the value of the MAV bit in the STB register and is therefore shown in Fig 5 4 Structure of an SCPI Status Register Each SCPI register consists of five parts each of 16 bits width which have different functions see Fig 5 3 The individual bits are independent of each other ie ea
31. Upper lower case characters are used to denote long and short form notation of command keywords The instrument does not differentiate between upper case and lower case characters A selection of keywords with the same effect exists for several commands These keywords are entered in the same line and are separated by a vertical stroke Only one of these keywords has to be indicated in the header of the command The effect of the command is independent of the relevant keyword entered Example SOURce AWGN BANDwith BWIDth The two following commands bring about the same effect They set the bandwidth of noise SOURce AWGN BANDwith SOURCe AWGN BWIDth A vertical bar in the notation of the parameters is used to separate alternative options and is to be seen as an or The effect of the command differs according to the parameter stated Example Selection of parameters for the command SOURce AWGN MODE SN SIGNal NOISe Keywords in square brackets may be omitted in compound headers see chapter 5 section Optional Keywords For reasons of compatibility with the SCPI standard the instrument must be able to recognize the full length of the command Parameters in square brackets may also be optionally inserted into the command or omitted Parameters in braces may be included in the command once several times or not at all 6 2 E 2 ABFS Common Commands Common Commands The common commands are based on the IEEE 4

List Editor The ABFS offers the facility of generating lists for automatic sequences of HOP mode and Memory Sequence The lists consist of elements pairs of values which are defined by an index and at least one parameter per index Each list is assigned a separate name and selected by means of this name Access to the lists is made in the associated menus For example sequences of instrument settings can be accessed in the MEM SEQ menu However the lists are always generated and processed in the same way and the procedures are hence explained in detail in this section by the example of the Memory Sequence Menu MEM SEQ Setting menus providing list processing are structured in two pages The first page called OPERATION page in the following contains the general configuration parameters for processing a list Further the general list functions such as selecting and deleting the list as well as calling an editing mode are provided The second page the EDIT page is automatically displayed when calling an edit function and serves to enter and modify the parameters of the list The OPERATION page has a similar arrangement with all list editors As an example the OPERATION page of the MEM SEQ menu is shown Menu selection MEM SEQ p ross al 0 0 ae ross a2 0 0 ae ODE MODE OFF AUTO SINGLE STEP EXT SINGLE EXT STEP FSIM AWGN RESET SEQUENCE P CALIBRATE EM SEQ CURRENT IND
