Status Registers

Use Status Registers to Determine the State of Analyzer Events and Conditions

STATus:OPERation Condition and Event Enable Registers

The STATus:OPERation condition register continuously monitors the hardware and firmware status of the analyzer, and is read-only. To query the register, send the :STATus:OPERation:CONDition? command. The response will be the decimal sum of the bits that are set to 1. For example, if bit number 9 and bit number 3 are set to 1, the decimal sum of the 2 bits is 512 plus 8. So the decimal value 520 is returned.

The transition filter specifies which types of bit state changes in the condition register will set corresponding bits in the event register. The changes may be positive (from 0 to 1) or negative (from 1 to 0). Send the

:STATus:OPERation:NTRansition <num> (negative transition) command or the :STATus:OPERation:PTRansition <num> (positive transition) command (where <num> is the sum of the decimal values of the bits you want to enable).

The STATus:OPERation event register latches transition events from the condition register as specified by the transition filters. Event registers are destructive read-only data. Reading data from an event register will clear the content of that register. To query the event register, send the

:STATus:OPERation:[:EVENt]? command.

The STATus:OPERation event enable register lets you choose the bits that will set the operation status summary bit (bit 7) of the status byte register to 1. Send the

:STATus:OPERation:ENABle <num> command 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 bit 9 or 3 is set to 1, the operation status summary bit of the status byte register will be set to 1), send the :STATus:OPERation:ENABle 520 (512 + 8) command. The :STATus:OPERation:ENABle? command returns the decimal value of the sum of the bits previously enabled with the :STATus:OPERation:ENABle <num> command.

STATus:QUEStionable Registers

STATus:QUEStionable registers monitor the overall analyzer condition. They are accessed with the :STATus:OPERation and :STATus:QUEStionable commands in the :STATus command subsystem.

The STATus:QUEStionable registers also monitor the analyzer to see if there are any questionable events that occurred. These registers look for anything that may cause an error or that may induce a faulty measurement. Signs of a faulty measurement include the following:

•hardware problems

•out of calibration situations

•unusual signals
