    Getting Started The 3026 Realtime Spectrum Analyzer has a GPIB interface. Almost all menu-controlled and front-panel controlled functions can be performed through the GPIB interface using the programming command set (described in Command Syntax). The GPIB interface conforms to ANSI/IEEE Std 488.1-1987, which specifies the hardware interface, its basic functional protocol, and a set of interface messages (codes) that control the interface functions.

  • Page 93: Status Registers

    Status and Events The interface in the 3026 Realtime Spectrum Analyzer includes a status and event reporting system that enables the user to monitor crucial events that occur in the instrument. The realtime spectrum analyzer is equipped with four registers and one queue that conform to IEEE Std 488.2-1987.

  • Page 98: Queues

    The event queue is a FIFO queue and stores events as they occur in the instru- ment. If more than 32 events occur, event 32 will be replaced with event code –350 (“Queue Overflow”). The oldest error code and text are retrieved using one of the following queries: H :SYSTem:ERRor? H :STATus:QUEue[:NEXT]? 3026 Programmer Manual...
