Bit Value Description
B7
status.standard.POWER_ON
status.standard.PON
Set bit indicates that the instrument has been
turned off and turned back on since the last
time this register has been read.
Bit B7 decimal value: 128
B8-B15 Not used Not applicable
As an example, to set bit B0 the standard event status enable register, set
status.standard.enable =
status.standard.OPC
.
In addition to the above constants,
standardRegister
can be set to the numeric equivalent of the bit to set. To
set more than one bit of the register, set
standardRegister
to the sum of their decimal weights. For example,
to set bits B0 and B4, set
standardRegister
to 17 (which is the sum of 1 + 16).

Example 1
standardRegister = status.standard.OPC
+ status.standard.EXE
status.standard.enable = standardRegister
Sets the OPC and EXE bits of the
standard event status enable register
using constants.
Example 2
-- decimal 17 = binary 0001 0001
standardRegister = 17
status.standard.enable = standardRegister
Sets the OPC and EXE bits of the
standard event status enable register
using a decimal value.
