Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7500A #9383199 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7500A spectrometer is a highly advanced and reliable piece of laboratory equipment, ideal for controlling the detailed composition of sample materials. It is used to measure the spectral profile of a sample, determining the emission or absorption of radiation in the sample in response to a given wavelength of light or radiation. It is especially useful for examining samples under different conditions, such as temperature and humidity, or even in space. HP 7500A has a range of features to accurately and precisely measure the spectral response of various samples. It consists of a voltage-controlled oscillator, a photon multiplier tube, monochromator and pre-amplifier. The voltage-controlled oscillator generates a voltage-controlled monochromatic light beam of adjustable wavelength, which is directed to the sample by the monochromator. The photon multiplier tube collects the sample's response in terms of light emission or absorption corresponding to the wavelength of the monochromatic light. Lastly, the pre-amplifier amplifies the signal from the photon multiplier tube to achieve a higher signal-to-noise ratio. AGILENT 7500A is also equipped with sensitive detector electronics for high accuracy in sample testing. It uses linear and non-linear analog-to-digital converters to accurately measure the sample's spectral profile. Additionally, the spectrometer has two analog input ports, including one for high voltage input from the pre-amplifier and one for current input from the photon multiplier tube. HEWLETT-PACKARD 7500A also has a high frequency scan mode that allows for extremely fast scans, up to a maximum scan rate of 50,000 spectra per second. With this scan mode, the spectrometer can collect increases in time resolution, while still achieving excellent spectral resolution. Additionally, the spectrometer has a noise floor of -130 dB/VT and a depth of spectroscopy of 3.2 µm/V. Finally, 7500A is easy to use and operate. It comes with a user-friendly software package that allows for easy measurement setup, setting of parameters for testing, data visualization and analysis. In summary, KEYSIGHT 7500A spectrometer is an excellent and reliable piece of equipment to measure the spectral profile of samples, providing great accuracy and precision.
