Using Status Registers
A wide range of status registers allows the oscilloscope’s internal processing status to be
determined quickly at any time. These registers and the instrument’s status reporting system are
designed to comply with IEEE 488.2 recommendations. Following an overview, starting this
page, each of the registers and their roles are described.
Related functions are grouped together in common status registers. Some, such as the Status
Byte Register (STB) or the Standard Event Status Register (ESR), are required by the IEEE
488.2 Standard. Other registers are device-specific, and include the Command Error Register
(CMR) and Execution Error Register (EXR). Those commands associated with IEEE 488.2
mandatory status registers are preceded by an asterisk <*>.
About these Commands & Queries
This section lists and describes the remote control commands and queries recognized by the
instrument. All commands and queries can be executed in either local or remote state.
The description for each command or query, with syntax and other information, begins on a new
page. The name (header) is given in both long and short form at the top of the page, and the
subject is indicated as a command or query or both. Queries perform actions such as obtaining
information, and are recognized by the question mark (?) following the header.
How they are listed?
The descriptions are listed in alphabetical order according to their long form. Thus the
description of ATTENUATION, whose short form is ATTN, is listed before that of AUTO
SETUP, whose short form is ASET.
How they are described?
In the descriptions themselves, a brief explanation of the function performed is given. This is
