Query Syntax
:OPERegister[:EVENt]?
The :OPERegister[:EVENt]? query reads and clears the integer value contained in
the Operation Status Event Register.
Table 77 Operation Status Event Register
Bit Name Description When Set (1 = High = True), Indicates:
14 IOF IO Operation Failed Event only when something causes the IO
operation to fail, like disconnecting a USB
device or interrupting the operation from the
oscilloscope's front panel.
13 IOC IO Operation Complete Event when any IO operation completes. IO
operations are any remote data request using
any interface (USB, LAN, or GPIB). For example,
if you connect to an oscilloscope using the USB
interface and then request waveform data, the
IOC bit will be set when the IO operation
completes.
12 HWE Hardware Event Event when hardware event occurs.
11 OVLR Overload A 50 Ω input overload has occurred.
