The header may be separated from Parameter 1 by either a space, comma,
equals sign or any combination of these. Parameters MUST be separated
from one another using a comma.
Headers and key-word parameters may be transmitted using either the
full or an abridged format. Both upper and lower case characters are
valid and may be used interchangeably.
Numbers must be in accordance with ANSI X3.42-1975 standards and may be
transmitted as integers, or in scientific notation, with or without
exponents. Waveform data values, however, can only be transferred as
integers (8- or 16-bits). Suffixes are optional (but acceptable only
when specifically mentioned).
Example:
The following commands are all legal ways of setting the vertical
gain
of CHANNEL i to I00 mV/div:
CHANNEL 1VOLT/DIV .I
CHANNEL 1VOLT/DIV,IO0 MVOLT
CIVD=IOOE-03 VOLT
CIVD I00 MV
The expression <i00 MV> is considered as a single parameter with a
suffix; therefore no comma is allowed to separate them. The space
separating the parameter value and the suffix is optional.

As well as specifying a new parameter setting, it is also possible to
query the 9400A in order to obtain a current value. Such queries are
always indicated by a question mark.
