What is CRO and its function?
INTRODUCTION: The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies. Its reliability, stability, and ease of operation make it suitable as a general purpose laboratory instrument.
What is a vector signal generator used for?
Vector signal generators are commonly used for receiver sensitivity testing. These generators typically can operate as arbitrary waveform generators for baseband signal generation or accept the AWG/AFG signals as inputs.
What are the sources of error in an oscilloscope?
Errors from nominal or variation with frequency of either the source output impedance or load impedance will have an effect on the signal level developed across the load – in this case the scope input.
What is the output of a function generator?
The function generator is made by BK Precision and is labeled as a 5MHz generator. (Model: 4011). The scope is a Tektronix 465B that is rated to handle at least 5MHz. The function generator has a TR and TF <= 120ps. Obviously the output is nowhere close to a square wave.
How are function generators used in SPECI abletime?
Function generators are signal sources which provide a speci ablevoltage applied over a speci abletime, suchas a \\sine wave” or\riangle wave” signal. These signals are used to control other apparatus to, for example, vary a magnetic eld (superconductivity and NMR experiments) send a radioactive source back and forth (M ossbauer
How are impedance mismatches affect an oscilloscope?
The design of dedicated oscilloscope calibration solutions minimise the effect of impedance mismatches, but calibration technicians and metrologists should be aware of their impact: The effect of scope input VSWR can easily be assessed and included as an uncertainty contribution when making bandwidth tests.
