Section 4 – Trace Memory and Cable Lists
Introduction
This section of the operator manual covers operations in the Memory menu
which includes:
•
Saving Traces
•
Recalling traces
•
Deleting Traces
•
Recalling traces to use as instrument setups
•
Editing the Cable List on the TDR
For information on using ETDR PC Vision for uploading traces to the PC or
uploading and down loading Cable Lists, refer to Section 5 ETDR PC Vision.
NOTE: The memories used to save traces and the Cable List are non-volatile
type of memory devices. The loss of battery charge, changing batteries, etc. will
not cause loss of any saved traces or cable types. However, it is prudent to
upload traces and save modified cable lists to a PC as soon as practical to
ensure 100% backup.
Saving and Recalling Traces
General
Traces saved in the TDR’S’s memory can be recalled on the TDR’s display or
uploaded to a PC using ETDR PC Vision software. Once uploaded to a PC, they
can be archived on the PC or other memory media. When a trace is saved it
also saves all the TDR setups for the cable type tested, Range, Z Scale, and
other TDR settings. When any trace is recalled on the TDR it will change the
TDR’s setups to the ones used when that trace was saved. This recalled setup
can be used to continue testing. See Recalling Test Setups later in this section.
