the keysight 538 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 538 incorporates a programmable alphanumeric display, accessible remoy 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 538 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.
