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 some
models, the limit is on +5dBm, some others are ok up to +10dBm but only 6G, 6G Combo, and the RF SMA
connector on the right side in a 3G Combo are protected up to +30dBm. See the table in page 41 for more
details.
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.
