Wavetek SAM 4040D Advanced HFC Signal Analysis Meter
The Wavetek 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 Wavetek 4040D offers a faster spectrum analyzer display, TDMA
measurements, and a new long-life battery.
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 4040Ds fast, sensitive spectrum display makes
finding ingress in the field quicker and easier. Waveteks 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.
Features:
-
See bursty noise, TDMA signals,
transients as short as 5 µs
-
Designed to work with highloss test
points available in todays amplifiers
-
Advanced TDMA digital measurements:
level, signal/noise, time-domain display
-
Five hour continuous use battery life
(battery and charger compatible with older Stealth units)
-
Existing SAM 4040s can be upgraded to
SAM 4040D functionality
