Appendix B: Specification
Since all information just listed is read out on screen, it appears on all hard
copies made by the oscilloscope. Therefore, hard copies of waveform plots
will also document the setup and measurement information associated with
the waveform.
Measurement Features
You can measure voltage or time on both NON-STORE (analog) and
STORE (digital) waveforms using the graticule. For STORE mode wave
forms, you can also measure voltage and time using CURSORS. (Wave
forms can be current acquisitions or SAVE REF acquisitions.)
The cursors are toggled to any displayed waveform of interest and then
positioned using the CURSORS knob to any two points of interest on the
waveform. The AV and AT readouts indicate the voltage difference and
timing difference between the positions of the cursors.
For 4 K acquisition records, the CURSORS knob also scrolls the record
back and forth horizontally, so any 1 K portion can be viewed on screen.
(The screen can oniy display 1 K record points.)
Options and
Accessories
For part numbers and information about both standard and optional acces
sories, refer to Options and Accessories which begins on page A-1 of this
manual. Your Tektronix representative, local Tektronix Field Office, or Tektro
nix products catalog can also provide additional accessories information.
Performance
Conditions
The following electrical characteristics (Table A-4) are valid when the instru
ment has been adjusted at an ambient temperature between +20° C and
+30° C (+68° F and 86° F), has had a warm-up period of at least 20 min
utes, and is operating at an ambient temperature between 0° C and +50° C
(32° F and 122° F), unless otherwise noted.
