The Analyzer contains several items of the same type, such as 16 channels, each of which in turn contains 16 traces, etc. A numeric suffix is used to denote the item number in a command. The suffix is added to the keyword of the item (channel, trace, etc.). For example, in the following specification the channel number <Ch> and trace number <Tr> indicate the channel and trace, to which this command is addressed:
CALCulate<Ch>:PARameter<Tr>:DEFine
According to this specification, the command referred to the trace 2 of the channel 1 will be written as follows:
CALC1:PAR2:DEF
The numeric suffix can be omitted. In this case, it is 1 by default. For example, the following commands are equivalent:
CALC:PAR:DEF
CALC1:PAR1:DEF
