The Status Model
Agilent 8163A Lightwave Multimeter, Agilent 8164A Lightwave Measurement System, & Agilent 8166A Lightwave Multichannel
System, Third Edition
The Operational/Questionable Status Event Summary Register
(OSESR/QSESR) summarizes the status of every module slot of your
instrument. If, for any slot, any bit of the QSSER goes from 0 → 1 AND
the corresponding bit of the QSSEM is 1at the same time, the QSESR bit
representing that slot is set to 1.
The Operational/Questionable Status Enable Summary Mask
(OSESM/QSESM) allows you to choose the module slots that may affect
the OSB/QSB of the Status Byte. If any bit of the QSESR goes from 0 → 1
AND the corresponding bit of the QSESM is 1at the same time, the QSB
of the Status Byte is set to 1. If you set a bit of the OSESM/QSESM to
zero, the corresponding module slot cannot affect the OSB/QSB. The
default is for all the bits of the OSESM/QSESM to be set to 0.
The Operational/Questionable Status Enable Summary Mask for the
Agilent 8163A Lightwave Multimeter and the Agilent 8164A Lightwave
Measurement System consists of one level. These are described in
"Status System for 8163A & 8164A" on page 30.
As the Agilent 8166A Lightwave Multichannel System has 17 module
slots, the Operational/Questionable Status Enable Summary Mask
consists of two levels. This is described in "Status System for 8166A" on
page 30.
