 A cursor selector;  is either or .
Commands can specify which measurement to set or query as a mnemonic in the
header. Up to four automated measurements may be displayed with each
displayed waveform. The displayed measurements are specified in this way:
Symbol Meaning
 A measurement specifier;  is either [top], , , or
[bottom].
Commands specify the channel to use as a mnemonic in the header.
Symbol Meaning
 A channel specifier;  is either , , , or .
