RF Explorer Power Limiter
The RF Explorer Power Limiter is a custom device designed from scratch to be the perfect protection against
strong RF fields.
All RF Explorer models have some power ranges for input signal beyond which can be damaged. For most
models, the limit is on +5dBm, some others are ok up to +10dBm but only WSUB3G (as well as the RF SMA
connector on the right side in a 3G Combo) is protected up to +30dBm.
The RF Explorer Power Limiter will allow any RF Explorer model to be
protected with external signals up to +30dBm (1 Watt), so you get
the same level of protection as in the WSUB3G. Furthermore, the
power limiter includes additional functionality inside that will
otherwise require external devices increasing cost and size:
Power limiter: protection up to +30dBm, for any frequency range
between DC-3000Mhz
DC block: You can connect any external DC source up to 16V with no
risk of damaging your RF Explorer or interfering in your
measurement.
Attenuator: Includes an internal 6dB attenuator to help you extend
the range of power signal measurements. 6dB attenuation means
only ¼ of the input power is received by the unit. To compensate for
this extra attenuation you should indicate OffsetDB: +006 in the
ATTENUATOR MENU of your RF Explorer.
