Atec Wavetek-JDSU-SAM-4040D - Manual

◆ See bursty noise, TDMA
signals, transients as short
as 5 µs
◆ Designed to work with high-
loss test points available in
today’s amplifiers
◆ Advanced TDMA digital mea-
surements: level, signal/noise,
time-domain display
◆ Five hour continuous use bat-
tery life (battery and charger
compatible with older
Stealth units)
◆ Existing SAM 4040s can be
upgraded to SAM 4040D
functionality
The new SAM 4040D includes all of the
same test capabilities of the Wavetek SAM
4040, but now more features are packed into
the same lightweight, durable package. The
new 4040D offers a faster spectrum analyzer
display, TDMA measurements, and a new
long-life battery.
Find Ingress Fast
One of the biggest problems with two-
way networks is ingress. Even though a
network may meet leakage guidelines,
lower frequency RF signals can still leak
into the cable; this is ingress. The portable,
durable SAM 4040D’s fast, sensitive spec-
trum display makes finding ingress in the
field quicker and easier.
Wavetek’s SAM 4040D is equipped with
a new impulse noise detector and more
powerful spectrum analysis modes. These
allow technicians to see noise spikes as fast
as 5 µs and track them down.
Measure TDMA or Continuous
Digital Signals
Wavetek’s SAM 4040D also offers a com-
plete set of digital signal measurements:
1)
Power level measurements can be made
on TDMA (‘bursted’) channels (cable
modems and most return path signals), as well
as continuous carrier channels (digital video
and most forward path signals).
2) Time-domain displays give more infor-
mation about TDMA channels. Packets of
data from a cable modem can be seen and
examined. Users can verify that all modems
are being received at the same level, see
‘collisions’, or get a quick idea of network
traffic levels from any point in the field.
3)
In-service in-channel D/U (desired/unde-
sired) measurements for TDMA signals. Now,
without taking modems out of service, users
can measure the level of interference in the
