    Status Byte Status Byte 6 ESB MAV EES EAV 1 Bits 0, 1, and 7 Not used (always 0) Bit 2 EAV (Error Available) Set to 1 when the error queue is not empty. In other words, this bit is set to 1 when an error occurs.
  • Page 98 6.2 Status Byte Operation of the Status Byte A service request is issued when bit 6 of the status byte becomes 1. Bit 6 is set to 1 when any of the other bits becomes a 1 (when the corresponding bit of the service request enable register is also set to 1).For example, if an event occurs and any of the bits of the logical AND of the standard event register and the corresponding enable register becomes a 1, then bit 5 (ESB) is set to 1.

    Output Queue and Error Queue Output Queue The output queue is provided to store response messages to queries. For example, if you send the WAVeform:SEND? command, which requests the output of acquired data, the data is stored in the output queue until it is read. As shown below, data are stored in order and read from the oldest ones first.
