AIN A/C FREQUENCY Sets the analyzer firmware for the frequency of the line power
supplied to the instrument (changing this requires the A/D to be
recalibrated (see below).
6.6.3.1
AIN CALIBRATED
Initiates a calibration of the D-to-A Converter circuit located on the
Mother Board.
6.6.3.2
AOUT CALIBRATED
Initiates a calibration of the
A1
,
A2
and
A3
analog output channels
that determines the slope and offset inherent in the circuitry of
each output. These values are stored in the and applied to the
output signals by the CPU automatically.
6.6.3.3
CONC_OUT_1
Sets the basic electronic configuration of the
A1
output. There are
three options:
RANGE: Selects the signal type and level of the output.
REC OFS: Allows them input of a DC Voltage to let the user
manually offset the output level.
CALIBRATED: Performs the same calibration as AOUT
CALIBRATED, but on this one channel only.
NOTE: Any change to RANGE or
A1
OFS requires recalibration of
this output.

CONC_OUT_2
Sets the basic electronic configuration of the
A2
output. There are
three options:
RANGE: Selects the signal type and level of the output.
REC OFS: Allows them input of a DC Voltage to let the user
manually offset the output level.
CALIBRATED: Performs the same calibration as AOUT
CALIBRATED, but on this one channel only.
NOTE: Any change to RANGE or
A1
OFS requires recalibration of
this output.

TEST_OUTPUT
Sets the basic electronic configuration of the
A3
output. There are
three options:
RANGE: Selects the signal type and level of the output.
REC OFS: Allows them input of a DC Voltage to let the user
manually offset the output level.
CALIBRATED: Performs the same calibration as AOUT
CALIBRATED, but on this one channel only.
NOTE: Any change to RANGE or
A1
OFS requires recalibration of
this output.
