The Spectrum mode has the speed and versatility to effectively
troubleshoot difficult system problems
Constellation display with MER and pre/post FEC BER
JDSU single-instrument solutions
The SDA-4040D Stealth Digital Analyzer delivers a single-instrument, “One-Box”
solution to help deploy and maintain quality video and data services in the HFC
network. With the same durability and measurement accuracy as its proven SAM
predecessor, the SDA-4040D is designed with the speed, spectrum, and advanced
QAM analysis to test both traditional analog video and the latest digital formats.
The versatile combination of standard features and available options enables the
meter to be customized, or upgraded to the SDA-5000, to meet virtually any
system requirements.

return path cable modem signals (DOCSIS, EuroDOC-
SIS, EuroModem)
Zero span/time domain expert mode, showing the
TDMA bursty return path cable modem power ramp

Advanced digital testing
– digiCheck average power
– QAM View digital analysis option with modulation error ratio (MER),
pre/post FEC BER, constellation, and exclusive noise/ingress under the carrier
measurement
Preparing the network for digital services
For measurement and analysis of digital TV and forward modem signals, the new
QAM View option provides a full complement of digital quality measurements.
Included is a 64/256 QAM constellation display with zoom, average digital power
level, bit error rate (BER), 21 to 35 dB modulation error ratio (MER) and noise
margin “cliff effect” parameter. An equalizer display shows equalizer stress and
distance to fault.
In addition, an exclusive QAM Ingress Noise mode enables technicians to
see ingress/noise under an active digital carrier. This tool is invaluable
for detecting forward path ingress otherwise hidden by conventional spectrum
views.
