Product Overview

The HM8123.02 from Rohde & Schwarz is a 3GHz programmable universal counter. The counter does measurement functions such as frequency A/B/C, period duration A, width A, totalize A, RPM A, frequency ratio A:B, time interval A:B, time interval A:B (average), phase A to B, duty cycle A, burst measurements. It has an 83mm x 21mm LCD display, power supply of 115V/230V ±10%, 45Hz to 60Hz, CAT II and consumes power of 20W approximately. This counter operate at temperature range of +5°C to +40°C and relative humidity ranging from 5% to 80% (non condensing).
