Precision Frequency Counter

Precision Frequency Counter Description

KEY STRENGTHS: VC-3165 is a high-resolution multifunction intelligent frequency counter based on microprocessor. Equipped with frequency, period and equal-precision measurement as well as with 3-step function selection, work state, unit and 8-digit LED display. All functions depend on a single CPU. The crystal controlled temperature cicuit provides constant compensation for temperature change which reduces the measurement errors typically caused by temperature drift. The channel B (CH.B) input provides an attenuator (x1, x20) and an AC/DC coupling for a low-pass filter. It can measure and show the frequency in between 0.01Hz - 2.5GHz on the LCD display. It also has a gate time that is continuously variable from 100ms to 10s and a maximum power consumption of only 5W. This versatile equipment produces high performance stability and function at a low cost without compromising its quality. STANDARDIZATIONS: We constantly keep in mind that the safety of the user should always comes first. We made sure that it passes the necessary testing of TÜV ISO9001:2000 to meet the quality management system conformity to have the acknowledged sign of safety and quality.
