® Additional basics on remote control R&S Messages and command structure Syntax for device-specific commands For demonstration purposes only, assume the existence of the following commands for this section: ● MEASure:CURRent[:DC]? ● MEASure:VOLTage[:DC]? ● FUSE[:STATe] {0 | 1} ● FUSE[:STATe]? Long and short form The mnemonics feature a long form and a short form.

® Additional basics on remote control R&S Messages and command structure SCPI parameters Many commands are supplemented by a parameter or a list of parameters. The parameters must be separated from the header by a whitespace (ASCII code 0 to 9, 11 to 32 decimal, e.g.

® Additional basics on remote control R&S Messages and command structure Example: OUTP:STAT ON OUTP:STAT? Response: 1 Text Text parameters observe the syntactic rules for key words, i.e. they can be entered using a short or long form. Like any parameter, they have to be separated from the header by a white space.
® Additional basics on remote control R&S Command sequence and synchronization An asterisk marks a common command. " Quotation marks introduce a string and terminate it. A whitespace (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates the header from the parameters.
The controller can be forced to wait for the corre- sponding action. The R&S NGU series does not support parallel processing of remote commands. If OPC? returns a "1", the device is able to process new commands.

® Additional basics on remote control R&S Status reporting system Depending on the value of the read register, you can draw conclusions on the current status of the device. For example, when the unit operates in constant voltage, the result of the returned ISUM register is a decimal "2" which corresponds the binary value of "0000000000000010".

® Additional basics on remote control R&S Status reporting system The CONDition register delivers a "1" (first bit set) in constant current mode (CC) and a "2" (second bit set) in constant voltage mode (CV). If the correct channel is selected and the red LED of the channel button lights up (CC mode), the query of the CONDition register must deliver a "1".
