Microtest TSB-67 - 568A Annex E Scanner User Manual


 
While in Automatic Increment mode, you can manually increment the last character by pressing the
Scanner’s ENTER key. In addition, you can use the
Ï and Ð keys to move to any character in
the Circuit ID, and you can use the
Ñ key to manually increment (or the Ò key to decrement)
the character at the cursor.
Note: When in Inc mode, pressing F3 will allow you use the arrow keys to move the cursor from
the Circuit ID field to the Save Sweep Data field.
If your Scanner does not have an alphanumeric overlay, press Edit (F2) to display the edit screen.
After editing, press Save (F1) to store your changes and exit or press the ESCAPE key to return
to the AUTOTEST RESULTS screen.
Save Sweep Data
When the Save Sweep Data field is selected in the SAVE TEST screen, several choices are
available:
When None is selected, Sweep data is not saved
When Attn is selected, all measured Attenuation points are saved with the Autotest
When NEXT is selected, all measured NEXT points are saved with the Autotest
When Both is selected, both Attenuation and NEXT are saved with the Autotest
When None is selected, no sweep data is saved. The worst case NEXT data point for each pair is
preserved in the saved Autotest. If you choose to save the NEXT sweep data, then every measured
next point is preserved. This permits you to view and print the graphs while viewing an Autotest
from memory. If this data is not saved, then the graphical information is not available except
immediately after the Autotest has been run, or in Measure Cable Performance.
Normally, 500 Autotests can be saved. However, saving full NEXT sweep and Attenuation sweep
data drastically reduces the number of Autotests, which can be saved. When saving Attenuation
data and both near and far end NEXT sweep data, perhaps only 40 tests can be saved. The specific
number of tests that can be saved is indeterminate, since the information is highly compressed prior
to saving. A cable, which has a smooth NEXT reading, will compress better than a cable with
jumpy NEXT. Also, some Autotests (such as a Category 3) specify the NEXT sweep range to be
smaller than a Category 5 Autotest; and fewer Autotests may be stored if the Autotest uses 100
kHz NEXT step size rather than TIA or 200 or 500 kHz steps.
