Designed for Your Technicians

The DSAM family models provide just the right collection of test tools

needed for technicians to do their jobs. The DSAM-2000 provides

installation technicians with a basic digital and analog signal analysis

meter. In addition to quadrature amplitude modulation (QAM) signal

analysis, including average power level, modulation error rate (MER),

and pre- and post-FEC (forward error correction) bit error rate (BER),

the DSAM-2000 measures analog video and audio levels as well as

carrier-to-noise ratio. Technicians can conrm DOCSIS connectivity

with a simple range and registration test that includes upstream

transmit level margin. A manager or supervisor can use StrataSync

to congure an autotest plan with a variety of measurements and

deploy it to a specic group or to all meters. Initiated with just two

button pushes, the autotest performs the same pass/fail test, the

same way, at any location, using the latest channel plan.

Service organizations can perform the same measurements with the

DSAM-2300 and go further by trouble shooting DOCSIS connections

and provisioning issues. With the DSAM-3300, Gigabit Ethernet testing

is included as well as full downstream spectrum mode and a QAM con-

stellation display. Technicians can make FEC BER, errored seconds, and

severely errored seconds measurements on deep-interleave 256 QAM

carriers with all DSAM-2000, -2300, -3300, and -6300 models.

Maintenance organizations use the DSAM-6300, which combines

all the DSAM functions with the for ward- and return-path Stealth

Sweep™ technology (patent No. 5585842) used in the JDSU Stealth

Digital Analyzer (SDA) products.

With powerful Stealth Sweep technology, the DSAM-6300 works with

existing SDA rack-mounted sweep gear (SDA-5500 and SDA-5510)

located at headend and hub sites. Additionally, the DSAM-6300 meters

can sweep side-by-side with SDA-5000 meters. Major network modi-

cations are not required.
