Table 3-2. Common Command Summary
The clear common command resets all event registers and removes all errors from the
error queue. It does not clear enable registers and transition filters. It also clears any
pending *WAI, *OPC, and *OPC? actions.
Sets the enable bits of the standard event enable register. This enable register contains a
mask value for the bits to be enabled in the standard event status register. A bit that is set
true in the enable register enables the corresponding bit in the status register. An enabled
bit will set the ESB (Event Status Bit) in the Status Byte Register if the enabled event
occurs. Parameter = NR1
This query command returns the contents of the standard event status register. Reading
the standard event status register clears the register.
This query command gets the manufacturer, model, serial number, and firmware level for
main and GPIB program in an ASCII response data element.
The response is: <Manufacturer>, <Model>, <Serial Number>, <Firmware Level>.
For example: Fluke,52120A,123456,1.00
The operation complete command causes the device to set the operation complete bit in
the standard event status register when all pending selected device operations have
completed.
The operation complete query puts an ASCII character '1' into the device's output queue
when all selected device operations have completed.
This query command gets a list of all the detectable options that are installed in the
Product. Options that are not installed are identified with an ASCII '0'.
There are no options for the 52120A as of this writing.
The reset command resets the instrument state. It is the third level of reset in the IEEE 488
3-level reset strategy. It has an effect only on the Product's functions and not the IEEE 488
bus.
The service request enable register contains a mask value for the bits to be enabled in the
status byte register. A bit that is set true in the enable register enables the related bit in the
status byte register to set a service request (SRQ). Parameter = NR1
This query command returns the value of the status byte. Bit 6 reports the master
summary status bit (MSS). The MSS is set if the instrument has one or more causes for a
service request.
The self-test query causes an internal self-test. The response is always 0 (pass).
The wait-to-continue command holds all commands to be done until all commands and
queries that are in process are completed.
