Appendix B - 2221 Operators
Q : What
is the
default number of
acquisitions in
ACCPEAK mode ?
A : No.
The
preamble
does not
indicate if
the
curve data
was taken at an A or a B SEC / DIV setting , just what
the SEC / DIV setting is for that curve data .
A : The number of sweeps that may be accumulated can
be set for a default of continuous ( ACQ NUM : ) or
any number
between 1
through 2047.
With each
new
acquisition , the most - positive and most - negative
values are added to the existing display . When set to
a
specified
number
, the
acquisition stops when
the
limit is reached , and the waveform is held displayed .
Q : Are the
intensified zones seen
in a 2230
BOTH
Horizontal Mode acquisition stored in SAVE mode or
in
SAVE
REF
memory ?
A : Yes
, they are
saved
in both
SAVE and
in
SAVE REF .

Q : What is the
envelope
sampling rate in
Peak Detect
and
Accumulated Peak
Detect ?
Q : What waveform data is sent by a 2230 if the
waveform
acquired
in
BOTH Horizontal
Mode
is
requested ?
A : 20
megasamples
per
second .
A : The A Sweep waveform is sent .
Q : Can the 2230 and 2221 cursor positions be addressed
over
the
communications
interface ?
Q : Can a
waveform be sent
to a
controller from the front
panel of the
oscilloscope
?
A : Yes . The cursors may be targeted to the acquisition
or a Save Reference waveform and positioned within
the waveform record . Their voltage difference and
time difference may be queried to determine the
readout values .
A : No , but the waveform may be sent to plotter or
printer . With
Option 10 , the
oscilloscope
must be in
Talk Only mode . With either option , the
PARAMETERS switch must be set to output the
correct format for the printer or plotter being used .
See Section 7 of the Operators Manual and the
Printer / Plotter Operation text in this Appendix for
information .
Q : Is delay time
included
in
the 2230
waveform
preambie ?
