IEEE 488.2 Common Commands
IEEE 488.2 Common Commands
Description
*CLS
The *CLS, clear status command, is defined in "IEEE Std 488.2-1992", 10.3. This command will also clear and
close the error message screen on the test set's display.
*ESE
The *ESE, standard event status enable command, is defined in "IEEE Std 488.2-1992", 10.10.
*ESE?
The *ESE?, standard event status enable query, is defined in "IEEE Std 488.2-1992", 10.11.
*ESR?
The *ESR?, standard event status register query, is defined in "IEEE Std 488.2-1992 ",10.12.
*IDN?
The *IDN?, identification query, is defined in "IEEE Std 488.2-1992", 10.14.*IDN? is used to retrieve
information about the test set in ASCII format.
*IDN?, returns ASCII codes 32 through 126 excluding comma and semicolon in four comma separated fields.
Field 1 returns the manufacturer, field 2 returns the instrument model number, field 3 returns the serial
number, field 4 returns 0.
*OPC
The *OPC, operation complete command, is defined in "IEEE 488.2-1992", 10.18. *OPC causes the test set to
continuously sense the No Operation Pending flag. When the No Operation Pending flag becomes TRUE, the
OPC event bit in the standard event status register (ESR) is set to indicate that the state of all pending
operations is completed. The *OPC common command is not recommended for use as an overlapped command.
*OPC?
The *OPC?, operation complete query, is defined in "IEEE Std 488.2-1992", 10.19. The *OPC? query allows
synchronization between the controller and the test set using either the message available (MAV) bit in the
status byte, or a read of the output OPC?. The *OPC? query does not effect the OPC event bit in the Standard
Event Status Register (ESR). The *OPC? common command is not recommended for use as an overlapped
command.
*OPT?
The *OPT?, option identification query, is defined in "IEEE Std 488.2-1992", 10.20. Each option will have a
unique name, that name will be retuned with the query.
*RST
The *RST command is defined in "IEEE Std 488.2-1992", 10.32. The *RST command is a full preset, which
restores a majority of settings to their default values.
