simultaneously. These are delta measurements; that is, measurements based on
the difference between two cursors.
Both H Bar and V Bar cursors can also be used to make absolute measurements.
For the H Bars, either cursor can be selected to read out its voltage with respect
to any channel’s ground reference level. For the V Bars, the cursors measure time
with respect to the trigger point (event) of the acquisition. The cursors can also
control the portion of the waveform on which automatic measurements are made.
For time measurements, units can be either seconds or hertz (for 1/time).
With the video trigger option installed (Option 05), you can measure the video
line number using the vertical cursors. You can measure IRE amplitude (NTSC)
using the horizontal cursors with or without the video trigger option installed.
Measure can automatically extract parameters from the signal input to the
Digitizing Oscilloscope. Any four out of the 25 parameters available can be
displayed to the screen. The waveform parameters are measured continuously
with the results updated on-screen as the Digitizing Oscilloscope continues
to acquire waveforms.
An important component of the multiprocessor architecture of this Digitizing
Oscilloscope is Tektronix’s proprietary digital signal processor, the DSP. This
dedicated processor supports advanced analysis of your waveforms when doing
such compute-intensive tasks as interpolation, waveform math, and signal
averaging. It also teams with a custom display system to deliver specialized
display modes (See Display, later in this description.)
Storage
Acquired waveforms may be saved in any of four nonvolatile REF (reference)
memories or on a 3.5 inch, DOS 3.3-or-later compatible disk. Any or all of the
saved waveforms may be displayed for comparison with the waveforms being
currently acquired.
The source and destination of waveforms to be saved may be chosen. You can
save any of the four channels to any REF memory or move a stored reference
from one REF memory to another. Reference waveforms may also be written
into a REF memory location via the GPIB interface.
I/O
The oscilloscope is fully controllable and capable of sending and receiving
waveforms over the GPIB interface (IEEE Std 488.1–1987/IEEE Std 488.2–1987
standard). This feature makes the instrument ideal for making automated
