What information is typically stored in a signal level meter's
(SLM) channel plan?
The SLM channel plan typically includes the channel number,
center frequency, channel bandwidth, modulation type, and
symbol rate.
What advantages are there to performing automated
measurements with an SLM?
Automated measurements help ensure consistent measurement
practices among different technicians.

What parameters of the RF carrier should be measured when
diagnosing or qualifying a digital TV (DTV) service?
To diagnose or qualify a DTV service, measurements such as
power levels, modulation error ratio (MER), bit error rate (BER),
etc. should be taken using a digital signal analyzer.
When connected directly to the broadband cable network, what
must be done to the digital television set for it determine each
channel's modulation and encoding scheme?
When connected directly to the broadband cable network, the
DTV must be instructed to "scan" all of the incoming channels
and store each channel's modulation and encoding scheme into
memory.
Which customers were originally targeted to use digital terminal
adapters (DTA)?
The DTA was originally targeted to those customers with analog
TVs that subscribed to basic-only service.

What technology enables individual digital set-top boxes (STB) to
receive authorization to access-encrypted program content via a
subscriber management system (SMS), aka billing system?
Addressable technology enables individual digital STBs to
receive authorization to access-encrypted program content via
an SMS.
What device is being deployed as the next evolutionary step for
the STB?
The cable gateway is being deployed as the next evolutionary
step for the STB.
What was a practical limitation of the integrated entertainment
system cabinet?
The size of the picture tube was limited to what could be installed
in the integrated entertainment system cabinet.

Why did the digital versatile disc (DVD) player/recorder replace
the videocassette recorder (VCR) in many entertainment
systems?
The VCR was replaced in many entertainment systems because
of the DVD's compact size, excellent video and audio quality, and
the player's ease of use.
What could happen if system components are stacked on top of
processor-intensive components such as a set-top box (STB)?
Stacking components on top of processor-intensive components
such as an STB can restrict the air flow that dissipates heat,
which can cause the STB to malfunction or fail.
What functionality has been added to many signal level meters
(SLM) to measure specific parameters of a digital modulation
carrier containing digital television and DOCSIS signals?
Digital signal analyzer functionality
