About TekScope Anywhere
Measurement differences
between TekScope
Anywhere and
Oscilloscope
This section provides details about differences in measurement results or
behavior between the TekScope Anywhere application and prior oscilloscope
measurement systems.
1. Populations per waveform for Cycle-based measurements Cycle Min and
Cycle Max may be lower by one or two in TekScope Anywhere.
■
DPOJET treats each half-cycle separately.
■
TekScope Anywhere makes a measurement only on each full cycle and
will ignore incomplete cycles at the start or end of a waveform.
2. Population per waveform for Cycle Pk-Pk will be half that of DPOJET
(possibly minus 1 or 2 due to boundary conditions).
■
DPOJET advances on a half-cycle after each measurement. So if positive
and negative half cycles are labeled {P1, N1, P2, N2, P3...}, DPOJET for
example would measure pk-pk across {P1, N1}, then across {N1, P2},
then {P2, N2}, then {N2, P3}, and so on.
■
TekScope Anywhere only makes one measurement per cycle, so {P1,
N1}, then {P2, N2}, and so on.
3. The High and Low measurements from DPOJET are named BitHigh and
BitLow in TekScope Anywhere. High-Low is named BitAmplitude for
consistency.
4. The CCPeriod measurement in TekScope Anywhere returns a different
measurement time value for each result than DPOJET's CCPeriod does.
■
This is to make the convention common with all the other CC
measurements in TekScope Anywhere.
5. In DPOJET, the Median and Fixed variants of Constant Clock Recovery
perform an internal classification of Clock versus Data. TekScope Anywhere
uses a single unified method everywhere.
6. The J2 and J9 measurements in DPOJET use a slight approximation of the
desired target BER level of 2.5e-3, whereas TekScope Anywhere uses the
exact value. This leads to a slight result variation.
7. Precision for gating measurements by time has been improved. Due to the
increase in precision, the waveform points selected as being inside the range
may now be different from other products, causing gated measurements to
return a more precise result than they did previously.
8. The reference level algorithms have been improved for consistency. In
DPOJET, different algorithms were used depending on the particular data
type behind the waveform. Now all waveforms use the same algorithm
regardless of data type. Consequently, some variance in calculated reference
levels may be seen compared to results returned by DPOJET and TekScope.
The differences are due primarily to an improvement in how the Automatic
method works. In TekScope, the MinMax method may have been chosen by
TekScope Anywhere™ Help 9
About TekScope Anywhere
the Automatic method while now it will choose Histogram Mode. Check the
method readout to be sure you get the expected ref level method or manually
select the specific method you would like to use.
9. The reference level algorithms between DPOJET and the base TekScope
have been unified in one place. Each product used different names for the
same algorithm, so new names were selected:
TekScope Anywhere TekScope Name DPOJET Name
Absolute Absolute Absolute
Automatic Automatic Auto
Min-Max Min-Max Min-Max
Histogram Mode Histogram Mode Low-High (Full Wfm)
Histogram Mean Histogram Mean N/A
Histogram Eye Center N/A Low-High (Eye Center)
10. Histograms in DPOJET used a left-edge-of-bin convention when identifying
bin positions, but for convergence with scope base measurements this has
been changed to a center-of-bin convention. This may lead to small results
differences for measurements that use histograms internally.
11. Measurement metadata readouts for reference levels, bit rate, pattern length,
RjDj and other items will have been accurate at the time they were calculated
but may not match the current settings until they are refreshed. To get the
most recent results, go to the measurement result table and confirm the
measurement updated. Then go back to the portion of the UI with the readout
to get the latest value. If that particular item is not in use by any
measurement, the readout will not be calculated. For example, if no
measurements are using reference levels, the readout will just say "TBD".
12. For all type II PLLs (including Standard BW, Custom BW and ExplicitClock PLL), DPOJET has a defect that was preventing the velocity variable
inside the PLL loop from dynamically updating. This has been fixed in
TekScope Anywhere.
13. Results for measurements using Explicit Clock Edges and Explicit PLL clock
recovery types will vary compared to DPOJET due to several improvements
to the algorithm.
14. Clock recovery is only run when a specific measurement configuration
requires it to avoid extra calculation overhead. Because of this, display units
have become a requested setting. If clock recovery was run as part of a
measurement calculation, the result will be displayed using the Unit Interval
if requested. If clock recovery was not run, the measurement until will remain
the normal display unit (typically seconds) as if Unit Interval had not been
requested.
15. Units will not be shown across any of the panels when the Loop Bandwidth
is narrow because the width is insufficient to get enough points for the
measurement. Increasing the width of the filter will propagate units
everywhere.

Plots
Histogram plot horizontal axis scaling is wrong in some cases, typically when a
measurement result has an extremely small standard deviation. In this case, the
plot will have a few vertical bars in the center, with mostly blank space on either
side.
Save and recall
1. tr0 format - Only Synopsys and LyncxSpice formats are supported.

General notes
You can share data acquired on an oscilloscope for offline analysis with
TekScope Anywhere. There are features available on an oscilloscope that are not
supported by TekScope Anywhere. The following list provides details about the
behavior of TekScope Anywhere, when recalling a session file saved on a DPO/
DSA/MSO oscilloscope.
■
Digital Sources, Bus, Masks and Limit setting features are not supported by
TekScope Anywhere. If the session file has these features, they are ignored.
■
Hbar and Vbar cursors are not available for analysis on TekScope Anywhere.
If the session file has Hbar and Vbar cursors, they are mapped to Screen
cursors.
■
TekScope Anywhere does not support multiple zooms. If the session file has
multiple zooms, only the Zoom1 settings are recalled on TekScope
Anywhere.
■
Waveforms are recalled at zero position on TekScope Anywhere regardless
of the vertical position set on the oscilloscope.
■
Eye diagram autoscale settings are ignored on TekScope Anywhere.
■
Should the application crash on start up, removing this file may resolve the
issue:
C:\Users\<username>\AppData\Local\Tektronix\TekScope Anywhere
\PowerUpSettings.ini
■
Microsoft Remote Desktop does not support the graphics used by this
software. Alternatives like TightVNC and Team Viewer are known to work.

Placing cursors on a
waveform
Cursors are used to take amplitude and timing measurements between screen
locations (screen cursors) and locations on a waveform (waveform cursors).
Cursors in Time domain view
You can use cursors to read the coordinate where each cursor (line) touches the
waveform and also view the difference (Δ) between the two cursors. Use these
steps to use cursors in a window (for precise measurements, zoom the waveform
in on the area of interest):
1. Turn on the cursors using the icons on the Time Domain view title bar.
2. Select and drag cursor A to the desired part of the waveform. The cursor
readout changes to reflect the cursor position.
3. Move cursor B by dragging the readout.
4. Move the pair by dragging the delta readout.
TIP. You can quickly access cursors by right-clicking on the screen and selecting
cursors from the context menu.
When multiple time domain waveforms are opened, turning the cursor on places
the cursors on the selected waveform. Selecting a waveform badge moves cursors
to the selected waveform (the horizontal or vertical cursor position doesn't
change).

■
Overlay mode draws the displayed waveforms in on top of each other.
Selecting a waveform badge causes that waveform to be drawn on top in the
Overlay mode.
■
Stacked mode shows the open waveforms stacked above each other for easy
horizontal comparison. You can toggle between the two modes based on the
required analysis.
When looking at edge crossings between two data signals, overlay mode may
be preferred. As the number of waveforms grows, stacked mode is typically
preferred.
Each waveform has a waveform handle, that can be used to move the waveform
vertically. Right-clicking the handle also provides easy access for configuring the
