Name Description
Hum Rejection
7
(Option 05 Video Trigger)
NTSC and PAL: –20 dB without any trigger spec deterioration. Triggering will continue
down to 0 dB with some performance deterioration.
1
The trigger position errors are typically less than the values given here. These values are for triggering signals having a
slew rate at the trigger point of
±
0.5 division/ns.
2
The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the
characteristics Sample Rate Range and Equivalent Time or Interpolated Waveform Rate on page 2–4 and Net Offset on
page 2–10.
3
The minimum pulse width and rearm width required for logic-type triggering or events delaying to occur.
4
The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on
the selected slope. The trigger point must not switch between opposite slopes on the waveform, and the display must not
“roll” across the screen on successive acquisitions. The TRIG’D LED stays constantly lighted when the SEC/DIV setting
is 2 ms or faster but may flash when the SEC/DIV setting is 10 ms or slower.
5
See the characteristic Sensitivity, Edge-Type Trigger, DC Coupled in Table 2–9, which begins on page 2–11.
6
The minimum signal levels required for stable logic or pulse triggering of an acquisition or for stable counting of a
DC-coupled events delay signal. Also, see the footnote for Sensitivity, Edge-Type Trigger, DC Coupled in this table.
(Stable counting of events is counting that misses no events or produces no extra events.)
7
The input signal is clamped at the bottom of the sync for the trigger path only. To remove the hum from the display, use a
Tektronix Video Display Clamp.

The time that reference waveforms, stored setups, and calibration constants are retained when there is no power to the
oscilloscope.

Data is maintained by small lithium-thionyl-chloride batteries internal to the memory ICs. The amount of lithium is so
small in these ICs that they can typically be safely disposed of with ordinary garbage in a sanitary landfill.
