Wavetek MS1300 Manual de usuario descargar pdf (Pagina 4)

A display of the spectrum with clear

pre-set limits allows the installer to easily

identify ingress. All intermittent ingress is

detected through flexible dwell-time setup

(MS1400).

digiCheck Digital

Signal Measurement

Making accurate digital average power and

performance measurements are addressed

with the digiCheck™ measurement func-

tion (MS1400). The digiCheck™ average

power measurement takes small slices of

the integrated RF-energy, summing them

together to provide one total power read-

ing. It takes into account the channel flat-

ness of the digital carrier itself.

▲ Digital-TV and forward cable

modem signal.

The digiCheck™ method of measuring

the total integrated RF-power under the

haystack is very reliable and accurate. All

level readings are fully compensated for by

the correct occupied bandwidth.

• Single Channel Display

and Six Channel Scan

have Pass/Fail indicators

for quick performance

• Installation Check -

Ensures FCC and CENELEC

compliance, reducing

subscriber call-backs

• Scan Mode - Shows all

channel levels at once,

graphically identifying

problems quickly and

easily.

• Channel Plans - can be

stored, built, edited

• Ingress Scan Mode -

allows users to find for-

ward and reverse ingress

problems from the tap to

the drop

• digiCheck™ Digital

Signal Measurement -

Measures DVB, Digital

TV, Cable Modem,

Internet, and Telephony

on-cable services

• International Languages

- Available on the LCD

screen allowing the user

to learn and read the

meter in their local lan-

guage:

“Small-band” digital

signals are like cable

telephone carriers.

"Small-band" digital carriers, like cable

telephony require a different measurement

technique. For that purpose, the

digiCheck™ feature offers a time average

as well. Even in this case, all level readings

are fully compensated for by the correct

occupied bandwidth.

Digital & Analog Limits

Cable networks have analog and dig-

ital carriers. The levels of analog and digital

signal measurements are different according

to standards and regulations. Digital signals

are typically 6-14 dB below analog signals.

Users can enter minimum and maximum

digital channel level limits separately from

analog limits. Scan Mode, Installation Check,

and Auto Test will accurately measure both

digital and analog signals. This allows easy

identification of the pass/fail condition of

both channel limits sets.

The MS1400 has a limit set for analog

channels and a limit set for digital channels.
