Key Benefits
To achieve service-dierentiating quality and reliability, network maintenance
requires careful and consistent attention. While the broadband frequency response
test in both the forward path (downstream) and the return path (upstream) is a
core requirement of any cable network maintenance plan, maintaining cable networks requires more than sweep. e DSAM-6300 (Digital Services Analysis Meter)
combines best-in-class video, audio, and data test functions with the extremely
popular SDA sweep system’s downstream forward path and upstream return path
sweep functions in a rugged, multi-technology handheld that performs in the harshest environments.
Because it uses powerful Stealth Sweep technology, the DSAM-6300 works with
existing Stealth Digital Analyzer (SDA) rack-mounted sweep gear (SDA-5500 and
SDA-5510) located at headend and hub sites. Additionally, DSAM-6300 meters
can sweep side-by-side with SDA-5000 meters. erefore, major test infrastructure modications are not required when DSAM-6300s are added to a department’s
meter pool.
• Improve workforce efficiency by letting technicians perform
complete maintenance and quality-verification tests on the
spot—one person with one instrument—including sweep,
digital video, analog video, DOCSIS®, VoIP tests, and more
• Streamline operations by managing and displaying sweep
files via the web and by immediately synchronizing data over
DOCSIS RF
• Minimize capital expenses—sweep is compatible with existing
JDSU Stealth Sweep™ systems, assuring non-interfering
forward- and reverse-sweep operations
• Improve technician competency with the Digital Quality
Index™ (DQI), an easy-to-understand, real-time indicator
that shows up to 90 seconds of digital quality history
• Stand up to rain, cold, heat, bumps, drops, and other

DSAM-6300 DigitAl Service AnAlySiS Meter
Features
Signal Level Meter
e DSAM-6300 features extremely accurate JDSU digiCheck™ digital power
level measurements in addition to traditional signal level measurement (SLM)
test functions for analog video and audio levels. In addition to the standard analog
carrier-to-noise (C/N) measurement, a quadrature amplitude modulation (QAM)
ingress option enables viewing noise and ingress within the QAM signal spectrum.
e DSAM-6300 can measure downstream carriers to a full 1 GHz and analyze
64, 128, and 256 QAM including deep interleave (i=128, j=4) modulation. Also
included are modulation error ratio (MER) and pre- and post-FEC bit error rate
(BER), margin, and quality specications.
The level mode on a digital channel measures
the signal level and MER and tracks the BER and
errored seconds.
Miniscan measures signal strength of up to
12 channels simultaneously.
Miniscan and Full Scan Modes
When measuring analog and digital signals, technicians can see high- and lowfrequency channels and verify how much level headroom remains when limits are
activated. In miniscan mode, the DSAM monitors up to 12 channels at a time and in
full scan mode it monitors the entire channel plan—up to 999 channels. e results
of both scans are displayed in either an easy-to-see bar graph or an informative table.
Tilt Mode
Part of the sweep procedure, tilt mode checks forward low- and high-frequency
channel level tilt. Level variances display at the bottom of the DSAM-6300 screen,
and a sampling of carrier levels throughout the spectrum provides a rough indication of frequency-response variation. Based on these results, technicians can choose
an equalizer pad that will provide optimum atness at the end of the line.
MER, BER, and Errored Seconds
When the DSAM 6300 is tuned to a QAM signal in the level mode, it simultaneously
measures MER, BER, and errored and severely errored seconds.
MER is an indicator of transmission quality degradation resulting from noise,
ingress, and composite distortions. An expression of signal-to-noise ratio plus all
other non-transient distortion signals, MER also shows phase and amplitude distortions that may have been passed from the headend. MER is an overall quality
measurement that can be performed on a digital QAM carrier. JDSU has perfected
this valuable measurement by optimizing both custom hardware and proprietary
soware algorithms. e result is accurate readings that far exceed those reported
from customer-premises equipment such as digital set tops.
Tilt mode checks forward low- and high-frequency
channel level tilt.
BER quickly detects impulse noise in the system by revealing when information is lost
or corrupted at the bit layer. e DSAM-6300 measures BER by tracking the number of
errored bits (pre-FEC) and the number of bits that cannot be xed by forward error correction (FEC) (post-BER).
e errored seconds measurement is for troubleshooting connections with intermittent bit errors occurring over a period of time. If an error has occurred during any
second of elapsed time, the errored second eld increments by one. One error or multiple errors in the same second is counted as one errored second. If there is more than
1 in 1 million bit errors occurring in the same second, the severely errored second
register increments by one. e errored seconds elds are conveniently included in
the digital level display.

A constellation graph shows impairments on the
network with patterns in the display. By identifying
the pattern, technicians can gure out the probable
cause of the impairment.
DSAM-6300 DigitAl Service AnAlySiS Meter
Constellation Mode
Various elements in a network can compromise video quality. e DSAM-6300 constellation mode displays patterns of data points on a graph for easy interpretation,
letting technicians detect and quickly diagnose sources of digital video problems.
Digital Quality Index (DQI) Mode
DQI is an indicator of the overall health of a QAM stream. is JDSU exclusive
measurement is extremely eective in tracking intermittent problems. QAM signal
health is represented by an easy to understand index rating from “0” to “10” with
10 being the highest quality. DQI also catches errors sometimes missed by BER and
errored seconds measurements. To help troubleshoot intermittent issues, the index
is plotted on a 180-second graphical history display.
QAM Ingress Mode
Traditionally, detecting the presence of ingress within downstream digital signal
spectrum is nearly impossible without turning o the service. e tightly spaced
QAM carriers hide any visual presence of ingress or intermodulation distortions. An
MER test will indicate that an issue exists, but with the DSAM-6300 and the patented
QAM Ingress mode, technicians can inspect what is actually going on beneath the
digital “haystack” without interrupting service.
DQI displays intermittent, short-duration impairments that MER and BER miss as well as steady-state
issues that MER and BER typically capture.
The QAM Ingress test lets technicians see spectrum
underneath a live digital carrier which is usually not
viewable due to the presence of the “haystack.”
Field View™ Option
Field View provides the communication between JDSU PathTrak™ return-path
monitoring systems and eld meters such as the DSAM-6300. A JDSU HSM-1000
sends spectrum measurements from PathTrak to the eld meter, where the results
are displayed on the DSAM screen. By comparing local spectrum measurements
to those from PathTrak, eld technicians can quickly resolve return-path ingress
problems.
The optional Field View capability greatly improves
the success rate and eciency in locating return-path
ingress. Field technicians can view the return spectrum that the JDSU PathTrak Return Path Monitoring
System receives. Both the remote spectrum and the
local spectrum view can be compared on the meter.

The Field View QAM dashboard shows a variety
of measurements for the represented carrier, and
results that are outside of user-designated limits are
indicated by color. From the dashboard, technicians
can select a measurement parameter to view more
closely and switch directly to a full-screen display of
that measurement.
DSAM-6300 DigitAl Service AnAlySiS Meter
Field View QAM™ Option
e unique Field View QAM option lets technicians see upstream impairments that
are invisible to spectrum analyzers and sweep tools. Observing a clean spectrum
with traditional spectrum-analysis tools may indicate a pristine return path;
however, the overall node health reported by the cable modem termination system
(CMTS) and other reporting tools can show a low health score, even aer teams
of technicians have been working on the node cleaning up noise issues for several
weeks. With Field View QAM, technicians can quickly identify micro-reections,
in-band frequency response, and group-delay issues. Armed with the DSAM in
conjunction with MACTrak™ technology in PathTrak, technicians can easily verify
the overall health of return-path carriers.
WiFi Option
e WiFi option enables a USB WiFi adapter to verify WiFi network strength and
connectivity, or to communicate test data to JDSU TechComplete™ Test Productivity
Pack (TPP).
The optical power measurement option enables
connecting a USB power meter (JDSU MP60A or
MP80A) for verifying or troubleshooting node light
levels.

DSAM-6300 DigitAl Service AnAlySiS Meter
Applications
Comprehensive Forward Path Analog and Digital Testing
With analog and digital testing combined in a single user interface, technicians
can select any specic channel or a scan of channels without having to dierentiate
between analog or digital video, high-speed data, or voice. e active channel plan
functions as a meter conguration le as well as a channel lineup. An extensive selection of conguration elements establishes the type of tests that can be performed on a
particular channel for each channel in the plan. Channel plans also include Autotest
congurations for analog, digital, and DOCSIS services. Congurations are entered
either directly into the meter or through the JDSU TPP client/server application soware that manages channel plans and measurement les for a collection of DSAM
meters. Congurations can also be conveniently cloned from meter to meter.
Networks with a history of multiple ownership transitions and/or diverse hardware
architectures are not a problem for the DSAM-6300. Supervisors can create multiple channel plans for a specied group of meters or one channel plan for the whole
network. e channel plans can be deployed with the ability to edit plan parameters
locked when needed. Specic plans are easily selected from Congure mode, or in
many cases, directly from within a measurement mode. Aer selecting an active plan,
technicians can check the top of the measurement screen to conrm that it is using
the correct plan. e channel plan name is included with any saved measurement le
for reference. Because Autotests are congured within a channel plan, multiple tests
can be run in a short period of time with only two button presses.
Summary view quickly identies overall
performance.
Test throughput to full DOCSIS 3.0 range.
Return- and Forward-Path Testing and Maintenance
e cable plant is a two-way communication path. As a vital link between customer
premises equipment (CPE) and the CMTS, the return path must be aligned and kept
free of ingress and noise. With digital services, limiting noise and ingress becomes
even more important as service degradation moves quickly from tiling or bit errors to
catastrophic failure.
e DSAM-6300 is designed to test and maintain both forward and return paths.
With its ability to sweep, conduct signal level and quality measurements, as well as
analyze ingress and noise, it provides the optimal approach to maintaining a hybrid
ber/coax (HFC) network.
DOCSIS Service Testing
As service providers face increasing competition, it is important to maintain a competitive lead in data service throughput. e ability to oer higher data rates is a
dierentiating advantage and improves a provider’s position as a preferred residential
or business data service operator. is advantage, along with the more-eective use of
valuable return-path spectrum, motivates service providers to migrate to DOCSIS 3.0
or to put this migration in their plans. To bolster the service provider’s reputation, it is
very important that new service oerings are of high quality and reliability, and testing
during installation and for system maintenance and troubleshooting is essential. e
DSAM DOCSIS 3.0 option lets technicians quickly and eciently test bonded channel
performance, signal levels, MER (including headroom), BER, and throughput to full
range—eight downstream by four upstream channels. Other IP-related tests include
packet loss and ping. e DSAM-6300 has a built-in cable modem capable of performing quick and accurate DOCSIS 3.0 RF and IP testing, eliminating the need for a test
modem to verify cable modem connectivity or a computer to test the CPE connection.

The VoIPCheck voice-quality verication test runs
over the DSAM’s cable-modem DOCSIS connection. It allows for segmentation between HFC and
IP issues by showing at which side of the CMTS
data impairments are present.
DSAM-6300 DigitAl Service AnAlySiS Meter
Voice over IP (VoIP) Testing
e DSAM-6300 VoIPCheck option enables service validation over a DOCSIS connection. With VoIPCheck, the DSAM-6300 can test VoIP services independently of
the VoIP specication being used. VoIPCheck can segment RF issues from IP issues,
helping to eliminate organizational nger pointing. e DSAM-6300 measures packet
statistics, including packet loss, jitter, and delay, as well as call-quality results such as
R-value and MOS. With its in-depth results analysis capability, the DSAM-6300 can
determine the source of call-quality problems, expediting the troubleshooting process.
Enhanced Downstream Spectrum
Technicians must be able to see how the network is behaving and troubleshoot spectrum-related problems. Most technicians do not require a fully featured and expensive
spectrum analyzer, and the DSAM’s enhanced downstream spectrum mode equips
them with an “everyday” spectrum analyzer. It lets users choose between two resolution bandwidth (RBW) settings, 330 kHz or 30 kHz, and modify the amount of time
spent measuring each frequency step, or dwell time of the analyzer, to a setting from
1 to 25 milliseconds. It also lets users see from 4 MHz to 1 GHz in 10 or 50 MHz spans.
Furthermore, if viewing return-path frequencies, technicians can activate an internal
low-pass lter to eliminate intermodulation distortion caused by relatively high-level
higher frequencies on the meter input, providing a cleaner upstream view.
Sweep
Service quality depends on transmitting signals with the highest carrier-to-composite
noise and the lowest intermodulation distortion. e majority of all transmission errors
can be detected by measuring the frequency response of the network. A sweep trace
reveals every physical error in the network that inuences transmitted signals. Also,
since sweep results are independent of transmission methods and formats, it is the most
eective and ecient method for technicians to set up the right gain versus frequency.
The DSAM’s enhanced downstream spectrum
mode equips technicians with an “everyday”
spectrum analyzer.

Sweepless Sweep provides a quick method to
check cable system integrity using active channels
to sweep the forward path. Sweep points do not
need to be added and no forward-path headend
gear is required.
DSAM-6300 DigitAl Service AnAlySiS Meter
Sweepless Sweep® Mode
For fundamental forward-distribution network alignment, the Sweepless Sweep
mode provides an economical solution. is mode scans the entire forward spectrum, displaying all levels across all frequencies (as dened by meter conguration).
Technicians can adjust the reception of the node amplier with this scan and then
normalize the display by saving a reference. e resultant display is a at zero-level
trace. When the measurement point is moved to the output of the RF amplier, any
changes due to the amplier will show as deviations (deltas) from the reference display. Because the cable network is designed on the unity gain principle, the same
reference is used as technicians test downstream ampliers to compensate for the
eects of each cable segment. To isolate the eects of headend changes in levels, or
to align portions of the spectrum where there are no active carriers to reference, the
forward sweep option should be considered.
Forward Sweep Option
e Forward Sweep option continuously references existing carriers to ensure an
accurate measurement result. e DSAM-6300 oers a fast forward sweep especially in systems with numerous digital channels. By referencing 64, 128, and 256
QAM signal types, the DSAM-6300 removes any worries about subscriber interference because there is no need to inject sweep carriers in the guard bands. Referencing
active carriers, instead of transmitting sweep signals over active carriers, lets the
DSAM-6300 sweep without degrading service quality.
Forward sweep uses a unique referencing
method to accurately reveal any problems in the
system without interfering with any of the analog
or digital carriers.
Tight reverse sweep points in the sweep plan display the entire return path with better resolution
and help to nd mismatches or other problems in
the upstream transmission path.
e SDA-5500 headend transceiver inserts sweep points in unoccupied spectrum
to test frequency response. To remove the eects of headend level dri, the instrument monitors levels and transmits new reference information with every sweep.
is means that if signal levels change in the headend, they will not aect the sweep
response measurement.
Reverse Sweep Option
Because the return path can be problematic, it should be tended to at least as oen as
the forward path; and, any impairments should promptly be xed. One of the best
procedures for preserving a clean return path is to establish an active reverse-sweep
maintenance plan. A reverse sweep can uncover mismatch problems, revealed as
standing waves, or diplex lter roll-os that can severely degrade the quality of services carried in the reverse band. e DSAM-6300 built-in reverse sweep transmitter
eliminates the need for a separate, cumbersome carrier generator.
Headend Sweep Equipment
With the DSAM-6300, one person can perform forward- and reverse-path alignment simultaneously. For reverse testing with more than one eld technician, the
rack-mounted SDA-5510 Headend Reverse Sweep Manager can perform reverse
sweep on the same cluster of nodes for up to 10 dierent technicians. e SDA-5500
transceiver used in conjunction with the SDA-5510 receiver provides a full forwardand reverse-sweep alignment solution. e SDA-5510 can also stand alone in remote
hub sites for dedicated reverse-alignment applications.
