RF EXPLORER
HANDHELD SPECTRUM ANALYZER
What is a spectrum analyzer ?
• A spectrum analyzer is an electronic instrument used to measure the
magnitude of an input signal across a range of frequencies. This device is
fundamental in characterizing and visualizing the frequency spectrum of
electrical signals, revealing the signal’s power distribution and any noise or
distortion present. Unlike oscilloscopes, which display signals in the time
domain, spectrum analyzers operate in the frequency domain, making it
easier to identify individual frequencies within complex signals and diagnose
sources of interference.
• Applications for spectrum analyzers are broad, including radio-frequency
testing, electromagnetic interference (EMI) compliance, and
telecommunications. They help engineers test devices by identifying harmonic
distortions and unwanted emissions that could interfere with other systems.
Introduction to RF Explorer
• RF Explorer is a portable, handheld spectrum analyzer primarily used
for RF (radio frequency) signal analysis.
• Designed for easy use in the field and lab, it is suitable for detecting
signal sources, interference, and noise across various RF bands.
Key Features
• Frequency Range: Covers frequencies from 15 MHz up to 2.7 GHz,
depending on the model.
• Real-Time Scanning: Offers real-time spectral data, allowing users to
monitor and track RF signals instantly.
• User-Friendly Interface: Includes a color display for visualizing signal
strength and frequency with minimal setup.
• Portability: Compact and battery-operated, making it ideal for remote
and on-site analysis.
Applications
• Wireless Network Analysis: Useful for assessing Wi-Fi, Bluetooth, and
cellular signals to detect interference sources.
• Electromagnetic Interference (EMI) Testing: Identifies unwanted
signals in environments requiring strict RF compliance.
• Amateur Radio and Broadcasting: Monitors broadcast bands,
amateur radio bands, and other RF applications

INPUT POWER LEVELS
Measurable input range Recommended external attenuator
Lower than -30dBm / 1 micro Watt No need
-30 to 0dBm / 1 microWatt to 1 milliWatt 30dB external or internal
-30 to 10dBm / 1 microWatt to 10 milliWatt 40dB external
0 to 33dBm / 1 milliWatt to 2 Watt 60dB external
Note there are three different power levels types to know when using spectrum analyzers, from lower to
higher:
Measurable input range: This range includes all levels the analyzer can correctly measure without distortion or
false reading. The above table shows typical levels for RF Explorer, see section External Attenuators in page 49
for recommended accessories to correctly perform any measurement you may need.
Safe but not measurable range: In this range the instrument will not get damage, the measurement will be
distorted and, in most cases, incorrect. Read section Protecting your instrument from damage in page 47.
Damage range: In this range the instrument may get permanent damage and readings may be incorrect at any
time.
