Power On Settings; Status Reporting - Metrix GX1010 Notice De Fonctionnement

During parallel poll response the DIO interface lines are resistively terminated (passive
termination). This allows multiple devices to share the same response bit position in either
wired-AND or wired-OR configuration, see IEEE 488.1 for more information.

5.1.4. Power on Settings

The following instrument status values are set at power on:
*
*
*
*Registers marked thus are specific to the GPIB section of theinstrument and are of
limited use in an ARC environment.
The instrument will be in local state with the keyboard active.
The instrument parameters at power on are determined by the setting of the POWER UP
field on the SYStem menu, see System Menu section. If POWER UP=POWER DOWN or
POWER UP=RECALL nn has been set and a defined state is required by the controller at
start up then the command *RST should be used to load the system defaults.
If for any reason an error is detected at power up in the non-volatile ram a warning will be
issued and all settings will be returned to their default states as for a ∗RST command.

5.1.5. Status Reporting

This section describes the complete status model of the instrument. Note that some
registers are specific to the GPIB section of the instrument and are of limited use in an
ARC environment.
5.1.5.1. Standard Event Status and Standard Event Status Enable Registers
These two registers are implemented as required by the IEEE std. 488.2.
Any bits set in the Standard Event Status Register which correspond to bits set in the
Standard Event Status Enable Register will cause the ESB bit to be set in the Status Byte
Register.
The Standard Event Status Register is read and cleared by the ∗ESR? command. The
Standard Event Status Enable register is set by the ∗ESE <nrf> command and read by the
∗ESE? command.

Parallel Poll Enable Register
Power On. Set when power is first applied to the instrument.
Not used.
Command Error. Set when a syntax type error is detected in a
command from the bus. The parser is reset and parsing
continues at the next byte in the input stream.
Execution Error. Set when an error is encountered while
attempting to execute a completely parsed command. The
appropriate error number will be reported in the Execution
Error Register.
Not used.
Query Error. Set when a query error occurs. The appropriate
error number will be reported in the Query Error Register as
listed below.
