Agilent / HP / Keysight 5384A
5384A Frequency Counter
Description
This counter utilizes interpolar enhanced reciprocal counting to provide outstanding performance at a low cost.
Frequency coverage allows measurements from 10Hz to 225MHz, with resolution of 9 digits per second.
It 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 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.
Key Points
High input sensitivity extends applications
Extensive input conditioning improves accuracy
Variable display digits improve readability
External DC operation extends portability
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.
