DiViSi DV 7633
Measurement calibration
Measurement calibration significantly reduces measurement uncertainty due to errors caused by transmission and reflection frequency response, source and load match, system directivity, and crosstalk.
For greater accuracy, especially for test setups with significant loss or reflection, user calibrations should be performed. For reflection measurement, one-port calibration is available . For transmission measurements,normalization calibration is available.
Normalization
Provides simultaneous magnitude and phase correction of transmission frequency response errors. Requires a through connection. Does not support calibration interpolation.
One-port calibration
Compensates for frequency response, directivity, and source match errors. Requires short, open, and load standards.
Application in devices production
DV7633/DV7631 deliver the best combination of speed, accuracy, productivity features, and low cost. These analyzers help reduce tune and test times, increase throughput, and lower your overall cost per component. They offer all the critical performance and features needed to test typical RF components such as: Filters, Amplifiers, Antennas, Cables, CATV taps and splitters.
Amplifier Measurement
With high precision receiver and accurate signal level from signal source, DV7633B/DV7631B can perform quality measurement, such as working frequency range, gain, flatness, AGC feature, return loss and isolation, and gain compression of amplifier. Also, power sweep is available to catch 1dB compression point of amplifier. DV7633/DV7631 provides various test and display modes to support high accuracy testing, especially for reflection strictly requested in bi-direction digital HFC network.
