REMOTE CONTROL Command Syntax Compatible Standard Command Structure IEEE488.2 Partial compatibility SCPI, 1999 Partial compatibility SCPI commands follow a tree-like structure, organized into nodes. Each level of the command tree is a node. Each keyword in a SCPI command represents each node in the command tree. Each keyword (node) of a SCPI command is separated by a colon (:). For example, the diagram below shows an SCPI sub-structure and a command example.
PAGE 50
PSW Series Programming Manual Query A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned. Example meas:curr:dc? Compound Two or more commands on the same command line. Compound commands are separated with either a semicolon (;) or a semi-colon and a colon (;:). A semi-colon is used to join two related commands, with the caveat that the last command must begin at the last node of the first command.
PAGE 51
REMOTE CONTROL Command Forms Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case. The commands can be written in capitals or lower-case, just so long as the short or long forms are complete. An incomplete command will not be recognized. Below are examples of correctly written commands.

REMOTE CONTROL Error Code Description -100 Command Error This is the generic syntax error for devices that cannot detect more specific errors. This code indicates only that a Command Error as defined in IEEE 488.2,11.5.1.1.4 has occurred. -102 Syntax error An unrecognized command or data type was encountered; for example, a string was received when the device does not accept strings.
PAGE 108
PSW Series Programming Manual -112 Program mnemonic too long The header contains more that twelve characters (see IEEE 488.2, 7.6.1.4.1). -113 Undefined header The header is syntactically correct, but it is undefined for this specific device; for example, *XYZ is not defined for any device. -114 Header suffix out of range The value of a numeric suffix attached to a program mnemonic, see Syntax and Style section 6.2.5.2, makes the header invalid.
PAGE 109
REMOTE CONTROL -141 Invalid character data Either the character data element contains an invalid character or the particular element received is not valid for the header. -148 Character data not allowed A legal character data element was encountered where prohibited by the device. -151 Invalid string data A string data element was expected, but was invalid for some reason (see IEEE 488.2, 7.7.5.2); for example, an END message was received before the terminal quote character.
PAGE 110
PSW Series Programming Manual Execution Errors Overview An in the range [ -299 , 200 ] indicates that an error has been detected by the instrument’s execution control block. The occurrence of any error in this class shall cause the execution error bit (bit 4) in the event status register (IEEE 488.2, section 11.5.1) to be set.
PAGE 111
REMOTE CONTROL -201 Invalid while in local Indicates that a command is not executable while the device is in local due to a hard local control (see IEEE 488.2, 5.6.1.5); for example, a device with a rotary switch receives a message which would change the switches state, but the device is in local so the message can not be executed. -203 Command protected Indicates that a legal password-protected program command or query could not be executed because the command was disabled.
PAGE 112
PSW Series Programming Manual -222 Data out of range Indicates that a legal program data element was parsed but could not be executed because the interpreted value was outside the legal range as defined by the device (see IEEE 488.2, 11.5.1.1.5.). -224 Illegal parameter value Used where exact value, from a list of possibles, was expected.

REMOTE CONTROL or query errors; see the other error definitions in this section. Error Code Description -310 System error Indicates that some error, termed “system error” by the device, has occurred. This code is device-dependent. -320 Storage fault Indicates that the firmware detected a fault when using data storage. This error is not an indication of physical damage or failure of any mass storage element.
PAGE 114
PSW Series Programming Manual Error Code Description -400 Query error This is the generic query error for devices that cannot detect more specific errors. This code indicates only that a Query Error as defined in IEEE 488.2, 11.5.1.1.7 and 6.3 has occurred.
