RFM 150 Instruction Manual 1–1
Product Description
The RFM 150 SignalScout is a high-performance RF signal meter
designed for cable television applications. It provides level
measurement capabilities and other features necessary to install and
maintain a cable television system. In-service carrier-to-noise and
hum measurements are provided, as well as a spectral display, an FM
detector, and a speaker.
Compatibility
The RFM 150 is designed to be compatible with NTSC, PAL, and
SECAM cable television systems. Channel tables for most countries
are built in, and you can load additional tables from a computer
(using the companion CSS150 software) or from another RFM 150.
The RFM 150 can measure the levels of dual-carrier sound systems,
including NICAM, analog dual carrier, and Korean dual carrier. It
can also measure the average level of digitally modulated carriers.
Level Measurement Modes
The RFM 150 supports the following measurement modes.
1 Channel Mode.
This mode displays visual carrier level (in dBmV or
dBuV), aural carrier difference (in dBc), channel number, and
frequency.
Pilots Mode. This mode simultaneously displays the levels of two
channels.
5 Channel Mode. This mode simultaneously displays the levels of five
channels.
Meter Mode. This is a general purpose level measurement mode
which you can use for peaking and/or nulling adjustments. The
results are displayed on a simulated analog meter.
