HP ESA Status Registers
Using the Analyzer Status Registers
command :STATus:OPERation:NTRansition <num> (negative
transition) or :STATus:OPERation:PTRansition <num> (positive
transition) where <num> is the sum of the decimal values of the bits you
want to enable.
The Operation Status Event Register latches transition events from
the condition register as specified by the transition filters. Event
registers are destructive read-only. Reading data from an event register
will clear the content of that register. To query the event register, send
the command :STATus:OPERation[:EVENt]?
Figure 2-4.
The Operation Status event enable register lets you choose which bits
will set the Operation Status Summary bit (bit 7) of the Status Byte
Register to 1. Send the command :STATus:OPERation:ENABle <num>
where <num> is the sum of the decimal values of the bits you want to
enable. For example, to enable bit 9 and bit 3 so that whenever either of
those bits is set to 1, the operation status summary bit of the Status
Byte Register will be set to 1, send the command
:STATus:OPERation:ENABle 520 (512 + 8). The command
:STATus:OPERation:ENABle? returns the decimal value of the sum of
the bits previously enabled with the :STATus:OPERation:ENABle
<num> command.
