TDS Family Oscilloscope Programmer Manual
The end-of-message terminator may be the END message (EOI asserted
concurrently with the last data byte), the ASCII code for line feed (LF) sent as
the last data byte, or both. The digitizing oscilloscope always terminates
messages with LF and EOI. It allows white space before the terminator. For
example, it allows CR LF.
Constructed Mnemonics
Some header mnemonics specify one of a range of mnemonics. For example, a
channel mnemonic can be either CH1, CH2, CH3, or CH4. You use these mnemon-
ics in the command just as you do any other mnemonic. For example, there is a
CH1:VOLts command, and there is also a CH2:VOLts command. In the command
descriptions, this list of choices is abbreviated as CH<x>.
When the application menu is displayed, commands may specify which menu
button to use.

RIGHT<x> A side menu button selector; <x> is 1, 2, 3, 4, or 5. Side menu
