14.4 Extended Event Register
The extended event register receives information about changes in the condition register, which
indicates the instrument's internal condition. The information is the result of edge detection performed
by the transition filter.

The condition register bits are described below.
Bit 0 EOS
(End of Sweep)
Set to 1 during a sweep operation.
EOS changing from 1 to 0 indicates that sweeping has
been completed (held).
Bit 1 OUT
(Output ON)
Set to 1 during output.
Bit 3 SCG
(Source Change)
When the output value is changed, this bit is 1 until the
output reaches 90% of the value.
Bit 5 EMR1
(FAN Stop)
Set to 1 when the cooling fan stops.
Bit 6 EMR2
(Temprature Error)
Set to 1 when an abnormal temperature is detected
inside the 2558A.
Bit 7 EMR3
(Amplitude Temprature Error)
Set to 1 when an abnormal amplifier temperature is
detected inside the 2558A.
Bit 8 EMR4
(Internal Power Error)
Set to 1 when an internal power supply error is detected
in side the 2558A.
Bit 10 FBE
(Feedback Error)
Set to 1 when a feedback correction error is detected.
Bit 11 OSC
(Oscillating)
Set to 1 when an amplifier oscillation error is detected.
Bit 12 LMT
(Limting)
Set to 1 when an overload is detected.
The transition filter parameters detect changes in the specified condition register bits (numeric suffixes
1 to 16) and overwrite the extended event register in the following ways.
RISE The specified extended event register bit is set to 0 when the corresponding condition
register bit changes from 0 to 1.
FALL The specified extended event register bit is set to 1 when the corresponding condition
register bit changes from 1 to 0.
BOTH The specified extended event register bit is set to 1 when the corresponding condition
register bit changes from 0 to 1 or from 1 to 0.
NEVer Always zero.
