The ‘:’ character is used as the path separator so the command string will be:
:MEAS:FUNC:Z
Note that the string starts with ‘:’. This tells the instrument to start from the ‘root’ path.
Whenever a terminator is reached (line-feed and/or EOI) the path is reset to the root path, so
each new GPIB command string must state the full path in order to work correctly, for example:
To set a measurement frequency of 1kHz at a level of 1.0V, the following string can be used:
:MEAS:FREQ 1k;LEV 1.0V <line-feed>
Or it can be expressed as two separate commands:
:MEAS:FREQ 1k <line-feed>
:MEAS:LEV 1.0 <line-feed>
However, the following will not work as the second command will be run from the ‘root’ path,
not the measurement path which was required:
:MEAS:FREQ 1k <line-feed>
LEV 1.0 <line-feed>
