SDA-5500/SDA-5510 Sweep Configuration: Forward Sweep Configuration (SDA-5500)

279

Single Carrier - Can be used for an FM or data carrier or CW.

Sweep Insertion Point - Used to insert sweep points into vacant

spectrum areas.

Digital Carrier - Can be used for digital carrier power

measurement. Only supported in the Level, Sweep, and

Spectrum measurement modes. An RMS detection mode is

used when measuring the level of a digital channel.

• Frequency: The frequency of the carrier (for TV and DUAL types, this is

the frequency of the video carrier, for Digital it's center) Enter frequency

by using the numeric entry keys or the arrow keys.

• Channel Number: The channel number of the carrier. Enter channel

number by using the numeric entry keys or the arrow keys.

• Label: The label is provided to associate a channel's number with it's

programming. Using the alpha keys, label the channel with a desired

name (up to four characters). "Special" characters can be selected using

the up/down arrow keys. The label will appear to the left of the channel

number on most screens.

• Sweep Channel: Y/N - Designates that the channel will be used for

Sweep measurements.

NOTE: Adding sweep points at increments other than 250

kHz will increase the dwell time by 15 msecs per non-250

kHz increment.

• Measurement Bandwidth Adjustments: To edit the bandwidth, cursor

to the Measurement BW selection. The bandwidth can be adjusted by

using the up and down arrow keys or by entering a value using the

numeric keypad and then pressing the Enter key. The FCC specification

for C/N measurements is a bandwidth of 4.200 MHz. CATV

organizations outside of the United States may have different

requirements.

• Noise Offset Frequency Adjustments: The frequency at which the

noise level is measured is the Carrier frequency plus the noise offset. To

adjust the noise offset, cursor to the Noise Offset selection. The offset

can be adjusted by using the up and down arrow keys or by entering a

value using the numeric keypad and then pressing the Enter key.

• Tilt Channel: Designates which channels are used for the Tilt mode. Up

to nine channels can be designated as Tilt channels.
