Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 53220A #9134174 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 53220A Single-Channel Frequency Counter is a general-purpose frequency counter capable of measuring frequencies up to 50 MHz with a resolution of 8 digits. HP 53220A is equipped with a dual-channel Schmitt trigger input and is designed to accurately measure low frequency waveforms. AGILENT 53220A features a large 5.7 inch LCD display with backlighting for easy viewing in dimly-lit environments and a user-friendly, easy to understand menu interface for convenient operation. The display area shows three separate parts: the first part is the waveform being measured, the second part is the meter character format, and the third part is the reading portion. KEYSIGHT 53220A has eight active AC/DC ranges that can be changed with a rotary switch. A pushbutton can be used to deactivate the particular range, to pause the current measurement, or to reset the device. 53220A can measure a variety of waveforms, including sine waves, square waves, triangular waves, and pulse waves. It also has a built-in measurement noise filter which helps reduce measurement noise and a frequency divider that allows for frequency division measurements. Additionally, HEWLETT-PACKARD 53220A is equipped with an external gate input which can be used to trigger a specific frequency measurement. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 53220A also features an internal clock and timer which allows the user to measure frequencies over preset time intervals. A data hold function is included which allows the user to store the current frequency measurement in memory and a comparison mode which can be used to compare the frequency accuracy of two different waveforms. In terms of accuracy, HP 53220A offers a range of 0.025Hz to 50MHz with a resolution of 8 digits. It has a basic accuracy of 0.5 ppm, as well as a 5ppm frequency stability over 32 to 77 degrees Celsius for a full year. AGILENT 53220A is powered by a 120 VAC wall plug and a 9 VDC internal battery and is rated for use in hazardous environments as it meets safety standards such as Class 1 - Division 2. In conclusion, KEYSIGHT 53220A Frequency Counter is an advanced, multi-functional frequency counter capable of measuring frequencies from 0.025Hz to 50MHz with a resolution of 8 digits. It is powered by 120 VAC power and offers a 5ppm frequency stability over 32 to 77 degrees Celsius for a full year. Equipped with advanced features such as its dual-channel Schmitt trigger input and external gate input, 53220A is a great choice for accurately measuring low frequency waveforms in hazardous environments.
