EIP Microwave 545 Overview

The 545 Microwave Frequency Counter is an exceptional counter. Frequency in the range of 10Hz to 18.0GHz is read directly from a 12-digit LED display which is sectionalized into GHz, MHz, kHz and Hz making it easy for even unskilled operators to make measurements quickly and accurately. Three input bands are standard: Band 1 is from 10Hz to 100MHz (sensitivity of 25 mV rms) with 1 Mohm impedance (BNC); Band 2 is from 10MHz to 1.0GHz (sensitivity of -20 dBm) with 50-ohms impedance (BNC); Band 3 is from 1.0GHz to 18.0GHz (sensitivity: -30 dBm from 1.0GHz to 12.4GHz; -25 dBm from 12.4GHz to 18.0GHz) with 50-ohms impedance (TYPE N). Time base crystal frequency is 10MHz with an aging rate of <3x10E-7 / month, 10MHz square wave (1 V p-p minimum into 50-ohms) output is available. Overall accuracy is (1 count + time base error). Other features include: Test function (allows for front-panel diagnostics), Sample Rate control (variable from 100 ms to 10 sec) and a Reset control.
