High-End ultra-low noise RF Preamplifier up to 6GHz. A "must have" for EMC measurements Extremely low noise Amplification of very weak signals Boosts any antennas gain Compensation of negative antenna gain Works with any brand of Spectrum Analyzers and directly fits any SPECTRAN. Broadband sensitivity increases by up to 30dB. The UBBV 0910 can be used anywhere a high gain, low noise amp is called for; digging out those weak shortwave signals or putting new life into that analyzer. Newly designed microwave chips enable the UBBV 0910 to have to gain up to 10GHz although we only spec the UBBV 0910 to 6GHz. The UBBV 0910 is the ideal general-purpose RF amp with extremely low noise that you'll wonder how you got along without. Another advantage of the UBBV 0910 is the very long battery run-time of up to 25 hours! Enables maximum performance, particularly when measuring extremely weak signals. Highly recommended for EMC and Pre-Compliance tests like EN55011, EN55022, EN50371, etc. A "must have" to get the maximum performance out of any SPECTRAN unit.
