Definition/Range
The values of the following variables change depending on the current instrument
settings. Each variable represents the value of the command function that has the
same name as the variable.

Value contained in one trace point. Notated as
TRA[N]
where N specifies the point
position
ln
the trace array. Values for N are 1 to 401 (for traces A, B, C) or 1 to 2047
(for traces specified by TRDEF). The same values apply to trace B
(TRB[N]),
trace C
(TRC[N]),
and user-defined traces (LABEL[N]).
trace range
Values contained in trace segment. Multi-point segments are notated as TRA[N,M],
where N and M are end points of a segment and specify point positions in trace array.
Values for N or M are 1 to 401 (for traces A, B, C), or 1 to the length of a trace as
specified by TRDEF. The same values apply to trace B (TRB[N,M]), trace C (TRC[N,M]),
and user-defined traces (LABEL[N,M]). Single-point segments are notated the same as
the trace element above.
units
user-defined function
Represent standard scientific units.
Frequency Units: GHZ or GZ, MHZ or MZ, KHZ or KZ, HZ
Amplitude Units:
DB, DM, DBMV, DBUV, V, MV, UV,
W,
MW, UW
Time Units:
SC, MS, US
Current Units:
A, MA, UA
Impedance Units:
OHM
A label 2 to 11 characters long that is
defined
by the FUNCDEF command. Choice of
characters is A through Z and the underscore
(-).
The underscore should be used as the
second character of the label. Omitting the underscore, or using the underscore as
other than the second character in a label, is not recommended.
user-defined trace
user-defined variable
A label 2 to 11 characters long that
is
defined by the TRDEF command. Choice of
characters is A through Z and the underscore(-). The underscore should be used as the
second character of the label. Omitting the underscore, or using the underscore as
other than the second character in a label,
is
not recommended.
A label 2 to 11 characters long that is defined by the VARDEF or ACTDEF command.
Choice of characters is A through Z and the underscore(-). The underscore should used
as be the second character of the label. Omitting the underscore, or using the
underscore as other than the second character in a label, is not recommended.
