The step size may also be changed during a scan.
The new step size will be in effect at the end of the
next count period. The scan is not reset or paused.
T DISC LVL = -10.0 mV
: -11.0 mV
The threshold level of T discriminator may be
adjusted from -300 mV to + 300 mV. This level is
the fixed threshold when T DISC is FIXED and
the starting level when T DISC is SCANned.
When the T DISC mode is SCAN and a scan is in
progress, this line displays the current position of
the T DISC level. The cursor is inactive and
replaced by a ':'. The spin knob cannot adjust the
threshold while it is scanning. When the mode is
SCAN, the starting level may only be adjusted
when the counters are in reset.
PORT1= FIXED
SCAN ∆=+0.100 V
The level of the rear panel PORT1 output may be
FIXED or SCANned. If the level is scanned, then
the right hand parameter is the step size. At the
end of each count period in a scan, the level is
incremented by one step size. The step size can be
varied from -0.500 V to +0.500 V. The range of a
scan is N PERIODS times the step size. The
starting level is set in the next menu line.
The scan mode may be changed during a scan. If it
is changed to SCAN, the level begins scanning
from the start value on the next count period. If it
is changed to FIXED, the level returns to the start
level immediately.
The step size may also be changed during a scan.
The new step size will be in effect at the end of the
next count period. The scan is not reset or paused.
PORT1 = +0.500 V
: +0.600 V
The level of the rear panel PORT1 output may be
adjusted from -10 V to +10 V. This level is the
fixed output when PORT1 is FIXED and the
starting level when PORT1 is SCANned.
When the PORT1 mode is SCAN and a scan is in
progress, this line displays the current position of
the PORT1 level. The cursor is inactive and
replaced by a ':'. The spin knob cannot adjust the
level while it is scanning. When the mode is
SCAN, the starting level may only be adjusted
when the counters are in reset.
PORT2= FIXED
SCAN ∆=+0.100 V
The level of the rear panel PORT2 output may be
FIXED or SCANned. If the level is scanned, then
the right hand parameter is the step size. At the
end of each count period in a scan, the level is
incremented by one step size. The step size can be
varied from -0.500 V to +0.500 V. The range of a
scan is N PERIODS times the step size. The
starting level is set in the next menu line.
The scan mode may be changed during a scan. If it
is changed to SCAN, the level begins scanning
from the start value on the next count period. If it
is changed to FIXED, the level returns to the start
level immediately.
The step size may also be changed during a scan.
The new step size will be in effect at the end of the
next count period. The scan is not reset or paused.
PORT2 = +0.500 V
: +0.600 V
The level of the rear panel PORT2 output may be
adjusted from -10 V to +10 V. This level is the
fixed output when PORT2 is FIXED and the
starting level when PORT2 is SCANned.
When the PORT2 mode is SCAN and a scan is in
progress, this line displays the current position of
the PORT2 level. The cursor is inactive and
replaced by a ':'. The spin knob cannot adjust the
level while it is scanning. When the mode is
SCAN, the starting level may only be adjusted
when the counters are in reset.
