Command and Query Syntax

Keysight N777xC Series Tunable Laser Family Programming Guide
All characters not between angled brackets must be sent exactly as
shown.
The characters between angled brackets (
that you should send, or that you get in a response. You do not type the
angled brackets in the actual message.
Descriptions of these items follow the syntax description. The following
types of data are most commonly used:
string is ascii data. A string is contained between double quotes ("...") or single quotes ('...').
value is numeric data in integer (12), decimal (34.5) or exponential format (67.8E-9).
wsp is a white space.
Other kinds of data are described as required.
The characters between square brackets ([...]) show optional information
that you can include with the message.
The bar ( | ) shows an either-or choice of data, for example, a|b means either
a or b, but not both simultaneously.
Extra spaces are ignored, so spaces can be inserted to improve readability.
