Operation manual
140
CME Command Error, bit 5. This event bit indicates that an incorrectly formed command or
query has been detected by the instrument.
EXE Execution Error, bit 4. This event bit indicates that the received command cannot be
executed, owing to the device state or the command parameter being out of limits.
DDE Device Dependent Error, bit 3. This event bit indicates that an error has occurred which is
neither a Command Error, a Query Error, nor an Execution Error. A Device-specific Error
is any executed device operation that did not properly complete due to some condition,
such as overload.
QYE Query Error, bit 2. The bit is set if the calibrator is addressed as talker and output queue is
empty or if control unit did not pick up response before sending next query.
OPC Operation Complete, bit 0. This event bit is generated in response to the *OPC command.
It indicates that the device has completed all selected pending operations.
ESE Event Status Enable Register
The Event Status Enable Register allows one or more events in the Event Status Register to be
reflected in the ESB summary-message bit. This register is defined for 8 bits, each corresponding
to the bits in the Event Status Register. The Event Status Enable Register is read with the common
query *ESE?. Data is returned as a binary-weighted value. The Event Status Enable Register is
written to by the common command, *ESE. Sending the *ESE common command followed by a
zero clears the ESE. The Event Status Enable Register is cleared upon power-on.
It suppresses or allows bits in ESR register. Value „0“ of a bit of ESE register suppresses influence
of appropriate bit of ESR register on value of sum bit of ESB status register. Setting of any
unmask bit of ESR register results in setting of ESB status register. ESE register value can be
modified by command *ESE followed by value of mask register (integer in range 0 –255).
Reading of the register can be performed with command *ESE?. The register is automatically reset
after switching on. The register is not reset with *CLS command.
Operation Status Register
Not used in the calibrator.
Questionable Status Register
Not used in the calibrator.
Output Queue
The Output Queue stores response messages until they are read from control unit. If there is at
minimum one sign in the output queue, MAV register (message available) is set. The Output
Queue is cleared upon power-on and after reading all signs from output queue.
