RF Explorer User Manual page 9
The RF Explorer Standard models includes 7 functional buttons in the front side. The unit also includes at
least one RF connector 50 ohm impedance standard SMA format.
All models have a SMA left connector installed and, optionally, some models have a second SMA connector at
the right position for extended range and functionality. For more details see the section Expansion Modules in
page 34.
The unit will automatically start running on USB power when a compatible mini-USB cable is connected.
Important: The internal battery power switch must be in the ON position for the battery to charge when the
USB cable is connected. The internal battery will not charge when the power switch is in the OFF position.
Note: There are a number of SMA adapters to easily interface RF Explorer SMA connector to any other
standard RF connector format, including BNC, N, RP-SMA, etc. For more information of adapters available see
section RF Explorer accessories in page 49.
Correctly handling input power levels
RF Explorer is specifically designed to get best results in low power signal detection using antennas. Most
measurements can be performed directly with no extra precautions. For best results, you may need to use
external attenuators if working with powerful signals.
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 43 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 41.
• Damage range: In this range the instrument may get permanent damage and readings may
be incorrect at any time.
RF Explorer models with internal Attenuator and LNA offer added flexibility to work with different input signal
levels.
