Keysight-Agilent 5330B

The 5330B Preset Counter offers normalized measurements using a preset (variable) time base. Thumbwheel switches allow the user to convert traditional counter measurements to read directly in engineering units such as RPM, GPM or PSI. The four operating modes provide the following measurements: rate (frequency), time (period), ratio, and F/MN (frequency division). Maximum input rate is 10MHz. The unit also has upper and lower limit testing capability.
