产品名称：频率计数器

The Agilent HP 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.

The half-rack width 5384A instrument is portable, rackable, and stackable for use in the field, at a workbench, or as part of an ATE system. Options include a four-hour-capacity battery pack, and a high-stability oven oscillator for higher accuracy.
 

   * High input sensitivity extends applications

   * Extensive input conditioning improves accuracy

   * Variable display digits improve readability

   * External dc operation extends portability

   * Proven reliability

   * 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.
