Agilent / Hewlett Packard 5385A
  USED  

The Agilent 5385A Frequency Counter utilizes interpolar-enhanced reciprocal counting
to provide outstanding performance at a low cost.
Frequency coverage allows measurements from 10 Hz to 1 GHz, with resolution of 9 digits per second.
The 5385A 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 5385A 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 ovenized oscillator for higher accuracy.

Features
High input sensitivity extends applications
Extensive input conditioning improves accuracy
Variable display digits improve readability
External DC operation extends portability
Standard TCXO timebase
Proven reliability
High Input Sensitivity
Sensitivity of at least 15 mV rms 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.
