Interface the StealthTrak to a PC with a Stealth-to-PC cable, P/N
1217-50-0158. The Stealth-to-Stealth interface cable is P/N 1217-50-
0149. The Stealth-to-Printer interface cable is P/N 1217-50-0159.
These three cables are different. Pin-outs and connector types are
available by calling Factory Support.

SYSTEM MODES OF OPERATION
The SAM 4040D Sweep System has the following modes of
operation:
Level Measurement
SAM 4040D offers several different level displays optimized to many
of the day-to-day tasks in maintaining your cable system:
•
SCAN mode displays a graph of the level of all channels in the
current channel plan, either with or without audio and digital
carriers. This mode is very useful when first connecting to a test
point. It allows a technician to quickly get a general idea of what
may be ‘going on’ with signal levels.
•
TILT mode provides the information needed to set the
equalization in an amplifier. Up to nine selected ‘tilt channels’
are measured and displayed at the same time. These can be
the pilot carriers or channels. The meter automatically calculates
tilt across these channels and displays their level.
•
LEVEL mode presents a detailed display about a single channel.
Video and audio levels are displayed both in bar graph and in
numeric form. The delta between audio and video level is also
computed. When a digital channel is measured, digiCheck
power measurement algorithms are used to accurately read
continuous digital carrier levels across the entire channel
selected.
Chapter 4 outlines level measurements in more detail.
