delimiter !$%&'/:=\@&^`|~A character, chosen from the above list, marks the
beginning and end of a string of characters. For simplified use, choose delimiters
that are not the same as any character within the string they delimit. Otherwise,
every occurrence of the delimiter character inside the string being delimited must
be replaced with a pair of delimiters when forming the delimited string.

lsb length Represents the least significant byte of a two-byte word that describes the number
of bytes returned or transmitted. See msb length.

number
Expressed as integer, decimal, or in exponential (E) form. Range: −10
+100
through
+10
+100
. The smallest positive fractional number that can be represented is
+10
−100
. This is the range of numbers that can be used in commands. This range is
further restricted when numbers are attached to specific types of units:
• frequency values are limited to ±1000 GHz.
• amplitude values are limited to ±300 dBm or ±300 dB.
• power values are limited to ±300 dBm or ±300 dB.
The above ranges can be further limited by hardware. These limitations are
identified under the individual command descriptions. Precision: approximately 15
decimal digits, unless otherwise limited by hardware. Length: the complete
number must be less than 25 characters.
