36 Keysight E1406A User Manual and SCPI Programing GuideConfiguring the Keysight E1406A Command Module Modules Configured Statically and DynamicallyTable FormatThe format of the dynamic configuration table is shown in Table 2-1.The table parameters are:– Valid Flag (1/0) 1 (one) indicates the table is valid and the modules can beconfigured accordingly. 0 (zero) will cause an error message (Error 39).Valid Flag is part of the table header and is one byte.– Number of Entries (1 - 254) is the number of entries in the table. Number ofEntries is part of the table header and is one byte.– Slot Number (1 - 12) is the mainframe slot the module to be assigned anaddress is installed in. Field is one byte.– Slot 0 Laddr is the logical address of the slot 0 device. This is 0 (zero) inmainframe #1 but will be different in any additional mainframes. Field isone byte.– Laddr (1 - 254) is the logical address to which the module in Slot Number isset. Field is one byte.– Block Size (1 - 128) is the number of devices in an address block. When thereis more than one device, Laddr specifies the logical address of the firstdevice in the set. The remaining devices are assigned sequential logicaladdresses beginning with the next highest address. When there aremultiple devices in a slot that are not address blocked, there must be anentry in the table for each device. Field is one byte.Determining the Table SizeThe dynamic configuration table has a two byte header and each of the fourfields are one byte. The amount of RAM to allocate withDIAGnostic:NRAM:CREate is computed as:2 + 4(N)Table 2-1 Dynamic Configuration Table FormatValid Flag Number ofEntriesSlot Number Slot 0 Laddr Laddr Block SizeSlot Number Slot 0 Laddr Laddr Block Size• • • •• • • •Slot Number Slot 0 Laddr Laddr Block Size
