*CLS –
CLEAR STATUS
Clears the MEASUREMENT EVENT, OPERATION EVENT, STANDARD EVENT and QUESTIONABLE EVENT registers, but
not their enable registers.
*ESE <NRf> –
PROGRAM STANDARD EVENT ENABLE REGISTER
A set bit in the STANDARD EVENT ENABLE register allows its corresponding event to set the ESB (event summary bit) in the
STATUS BYTE register. <NRf> is an ASCII string representing an integer mask. For instance, a value of 45 decimal is the same
as binary 00101101, thus setting bits 5, 3, 2 and 0 in the enable register.
*ESE? –
STANDARD EVENT ENABLE REGISTER QUERY Returns the contents of the STANDARD EVENT ENABLE register.
*ESR? –
STANDARD EVENT REGISTER QUERY Returns the contents of the STANDARD EVENT register.
NOTE: The STANDARD EVENT register is cleared after an *ESR? command.
*IDN? –
IDENTIFICATION QUERY
Returns the following string: F.W.BELL, MODEL 5180,Rx.x. The Rx.x string is the firmware revision level, where x.x is a decimal
number, such as 1.1.
*OPC –
SET OPERATION COMPLETE
Causes the OPC (operation complete) bit to set in the STANDARD EVENT register when all commands have been executed.
*OPC? –
IDENTIFICATION QUERY
Causes the OPC (operation complete) bit to set in the STANDARD EVENT register and returns an ASCII “1” when all
commands have been executed.
*OPT? –
OPTION IDENTIFICATION QUERY
Returns a string that identifies the model number and serial number of the Hall probe. The model number will always be 12
characters in length including trailing spaces, such as STD580404. Following the model number will be a comma (,). Next will
be the serial number, which will always be ten characters in length including trailing spaces, such as 0523004. If no probe is
attached or can’t be identified, the string will default to “UNDEFINED ,0”.
*SRE <NRf> –
PROGRAM STATUS ENABLE REGISTER
A set bit in the STATUS ENABLE register allows its corresponding event to set the RQS (request for service) in the STATUS
BYTE register. <NRf> is an ASCII string representing an integer mask. For instance, a value of 45 decimal is the same as
binary 00101101, thus setting bits 5, 3, 2 and 0 in the enable register.
*SRE? –
STATUS ENABLE REGISTER QUERY returns the contents of the STATUS ENABLE register.
*STB? –
STATUS BYTE QUERY returns the contents of the STATUS BYTE register.
NOTE:
The STATUS BYTE register is not cleared after an *STB? command.
Other registers and buffers must be cleared for the bits in the STATUS BYTE register to be cleared.
