HP-Agilent/Keysight 5384A

The Agilent 5384A Frequency Counter utilizes interpolar-enhanced reciprocal counting to provide outstanding performance at a low cost. Frequency coverage allows measurements from 10 Hz to 225 MHz, with resolution of 9 digits per second. The 5384A incorporates a programmable alphanumeric display, accessible remotely via either HP-IB (standard) or HP-IL (optional). The liquid crystal display (LCD) reduces component count, is easy to read (indoors or out), and improves counter reliability and serviceability. – High input sensitivity extends applications. – Extensive input conditioning improves accuracy. – Variable display digits improve readability. – External dc operation extends portability. – Proven reliability. – For complete details, click on the Data Sheet link. – High Input Sensitivity. – At least 15 mV rms sensitivity reduces the need for preamps and improves low-level signal measurement accuracy. – Extensive Input Conditioning. – A low pass filter, automatic or manual attenuator and trigger level control features provide versatile signal-to-noise conditioning for optimum accuracy. – Variable Display Digits. – View only readable digits from stable signals by controlling the number of display digits. Use as few as 3 or as many as 11 digits. – External dc Operation. – Wide range (9-15V) external dc input power allows use of sources such as 12V automobile power to keep the timebase warm, or charge the battery option while in transit to remote sites.
