Introduction to Programming

Program Data Syntax Rules

All numbers must be strings of ASCII characters. Thus, when sending the

number 9, you would send a byte representing the ASCII code for the character

9 (which is 57). A three-digit number like 102 would take up three bytes (ASCII

codes 49, 48, and 50). This is handled automatically when you include the entire

instruction in a string.

Embedded Strings

Embedded strings contain groups of alphanumeric characters, which are

treated as a unit of data by the oscilloscope. For example, the line of text written

to the advisory line of the instrument with the :SYSTEM:DSP command:

:SYSTEM:DSP "This is a message."

Embedded strings may be delimited with either single (’) or double () quotes.

These strings are case-sensitive, and spaces act as legal characters just like any

other character.
