Tektronix 2230

Appendix B-2230 Operators
Q: What is the default number of acquisitions in
ACCPEAK mode?
A: The number of sweeps that may be accumulated can
be set for a default of continuous (ACQ NUM:0) 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: What is the envelope sampling rate in Peak Detect
and Accumulated Peak Detect?
A: 20 megasamples per second.
Q: Can the 2230 and 2221 cursor positions be addressed
over the communications interface?
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.
Q: Is delay time included in the 2230 waveform
preamble?
B-20
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.
Q: Are the displayed intensified zones seen in a 2230
acquisition stored in either SAVE mode or in SAVE
REF memory?
A: Yes, they are saved in both SAVE and in SAVE REF.
Q: What waveform data is sent by a 2230 if the
waveform acquired in BOTH Horizontal Mode is
requested?
A: The A Sweep waveform is sent.
Q: Can a waveform be sent to a controller from the front
panel of the oscilloscope?
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
