Status Reporting System (Option R&S FSV-K91)
The status reporting system stores all information on the current operating state of the
instrument, e.g. information on errors or limit violations which have occurred. This infor-
mation is stored in the status registers and in the error queue. The status registers and
the error queue can be queried via IEC bus.
In this section, only the new and altered status registers/bits for the WLAN option
(R&S FSV-K91) are described. Detailed information on the status registers of the base
system is given in the section "Status Reporting System" in chapter 5 of the Operating
Manual on CD. A description of the remote commands required to query them is provi-
ded in "Remote Control – Description of Analyzer Commands" >"STATus:QUEStiona-
ble Subsystem" in the base unit documentation.
Description of the Status Registers
The WLAN option (R&S FSV-K91) uses only status registers provided by the base unit.
However, some registers are used differently, as described in the following sections.
