- Event Register and Status and Error Reporting
Event Register and Status and Error Reporting
The standard Event Status Register (ESR) may be utilized to indicate the instrument status. Each of six
bits within the eight-bit register indicates a different condition within the 2411B:
ESR - Standard Event Status Register

URQ
CME
EXE
DDE

Functional Syntax Elements
In order to establish programming consistency among different manufacturers' devices, IEEE-488.2 has
defined a set of rules governing message headers, mnemonics, separators and data types. The following
overview which is very similar to the GPIB counterpart will familiarize the programmer with the
fundamentals of these rules. As seen below, the rules for command and query messages are much more
flexible than their precise response message counterparts. The rule can be summed up as "Forgiving" lis-
tening and "Precise" talking.
<PROGRAM MESSAGE UNIT> - This is the basic message, and represents an operation to be per-
formed by the device. As an example, if you wanted to create a sinewave with 5 cycles in the currently
selected waveform, the appropriate <PROGRAM MESSAGE UNIT> would be:
WVFM:SINE 5,0
Notice that a colon (ASCII 3A) is used to separate the <program mnemonic> WVFM from SINE. For
query responses the similarly structured <RESPONSE MESSAGE UNIT> is used. A complete list of
<PROGRAM MESSAGE UNITS> and <RESPONSE MESSAGE UNITS> for the 2411B, with defini-
tions, mnemonics, and limitations is given in chapter 7.
