in generating the sweep.

Duration of bias level in milliseconds

Upon
power-up,
or
after receiving a DCL
or
SOC
command, the instrument defaults
to the last programmed selections. All items
in
the sweep buffer are preserved.
A
JOX
command restores factory default values of
IV

for level/start,
IOV

/lmAforstep,llV
/lOmAforrange,Omsecfordelay,lOfor
count/pulses,
10 log points
per
decade,
and
lOOmsec
for
toN/toFF.
All items in the
sweep buffer are cleared.
The
Q
command creates
or
appends a sweep list
by
defining the parameters of a se-
lected sweep type. The sweep types include: fixed level, linear stair, logarithmic
stair, fixed level pulsed, linear stair pulsed,
and
logarithmic stair pulsed.
