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

SAM 4040D
