Keysight IO Libraries Suite software. If you have installed other I/O software, refer to the documentation that accompanies the software. 1 After the I/O software has been installed on your PC, connect the 8990B to your PC using a Type A-to-Type B USB cable.
Page 32 Keysight IO Libraries Suite software. If you have installed other I/O software, refer to the documentation that accompanies the software. 1 Using a standard LAN patch cable, connect both the PC and the 8990B to LAN outlets. 2 Use the Connection Expert utility of the IO Libraries Suite to add the 8990B and verify the connection.
Page 33 – If the 8990B is not detected automatically on the Connection Expert, you can NOTE manually insert a known IP address of the 8990B to detect it. To obtain this IP address, go to the 8990B front panel display and select Tools > Remote Setup.
Page 34: Status Reporting
8990B Remote Operation Status Reporting Status reporting is used to monitor the 8990B to determine when events have occurred. Status reporting is accomplished by configuring and reading status registers. The 8990B has the following main registers: – Status Byte Register –...
Page 35 Condition register The condition register continuously monitors the hardware and firmware status of the 8990B. There is no latching or buffering for this register; it is updated in real time. Condition registers are read-only. Transition filter The transition filter specifies which type of changes to the bit state in the condition register will set corresponding bits in the event register.
Page 36 Consider Case C, where the positive transition filter is set to 1 and the negative transition filter is set to 0. This configures the 8990B to set the corresponding bit in the event register whenever the condition bit changes from 0 to 1. The enable register is set to 1 to enable the summary bit to be generated each time there is a change in the event register.
Page 37 Consider Case D, where the positive and negative transition filters are set to 1. This configures the 8990B to set the corresponding bit in the event register whenever there are changes to the condition bit. The enable register is set to 0 to disable the summary bit to be generated.

Page 39 Status Byte summary register The Status Byte summary register reports conditions from other status registers. Query data waiting in the 8990B output buffer is immediately reported through the “Message Available” bit (bit 4). Clearing an event register clears the corresponding bits in the Status Byte summary register.
Page 40 (status byte query) is similar to a serial poll except that it is processed like any other 8990B command. The *STB? query returns the same result as an IEEE-488 serial poll except that the request service bit (bit 6) is not cleared if a serial poll has occurred.
Page 41 Questionable Status register The Questionable Status register set provides information on the quality of the 8990B measurement results. Any or all of these conditions can be reported in the questionable data summary bit through the enable register. You must write a value using the STATus:QUEStionable:ENABle command to set the enable register mask.
