The Keysight (Agilent) 5386A Frequency Counter measures frequencies from 10Hz to 3GHz using advanced GaAs prescaler and attenuator technology. It achieves -23.5 dBm sensitivity, 30.5 dB dynamic range, and +25 dBm damage level. Featuring a 12-character LCD readable in direct sunlight, the unit supports HP-IB control, reciprocal counting, interpolation, and optional high-stability ovenized oscillator (Option 004). The design minimizes switching, using only two input ports for full frequency coverage.
Its compact half-rack size and portability make it ideal for both lab setups and on-site calibration. The flexible display and unit control options ensure usability in dynamic test environments requiring clear visibility and precision.
Testwall can supply the used Keysight (Agilent) 5386A, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality.
