rf signal generator

All accuracy measurements are specified in terms of parts per million (PPM). This is the level of noise in a 1 Hertz bandwidth relative to the level of the carrier. These need to be added statistically to gain the overall "accuracy" for the radio frequency signal generator. RF Signal Generators have maximum frequencies that vary per model, but generally accepted maximum is 6 GHz, which overlaps with Microwave Generators that start in the MHz range up to 20 GHz maximum. It is necessary to work out what is needed, and what will be needed to enable the best option to be chosen. Today a variety of modulation formats may be available in a signal generator. Rent Signal Generator.

Tektronix signal generators cover a wide range of applications, from replicating sensor signals to creating RF and the fastest high speed serial data signals. Often the performance is reflected in the price, and in view of the technology used in RF signal generators, they are often not cheap. With most RF signal generators using frequency synthesizers, this means that the frequency accuracy is determined by the frequency standard used within the generator. RF signal generators vary considerably in performance. The actual levels may be given at several points in a specification, and sometimes a plot of the phase noise may be given.Phase noise levels are measured in terms of dBc / Hz. These may be will outside the operating frequency range of the unit under test, and the signal generator will need to accommodate these and any other requirements.All signal generators produce some level of spurious signals. The frequency coverage required for the signal generator may not be just that of the unit under test.

The accuracy of the attenuator then provides the relative accuracy of the individual steps while the maintained level of the amplifier provides the absolute level accuracy.

However there are elements including temperature stability, line voltage stability, ageing (i.e. In this way real signals can be more fully simulated and the required tests undertaken. Next, we will consider RF signal generators in which the RFsource is a frequency synthesiser, and also communications service monitors.The latter are combination instruments embodying the functions of an RFgenerator, an audio generator, a test receiver and a modulation meter. Many signal generators today are able to operate well into the microwave region as this is an area of growing interest.When choosing the band required for a signal generator it is necessary to consider all the testing that will be needed. Each versatile signal generator can create a virtually unlimited number of signals - analog or digital, ideal or distorted, standard or custom. Often the performance is reflected in the price, and in view of the technology used in RF signal generators, they are often not cheap. Frequency is a measure of how fast a repetitive signal repeats per unit time and commonly measured in Hz (cycles per second). When making general noise measurements of a system, the phase noise of a signal generator used may affect the measurements. The importance arises because many signal generators are fall into the category of a synthesized signal generator. The design is based on two lCs only, and uses ready-made inductors in the frequency determining sections.

It is necessary to ensure that the radio frequency signal generator being considered is able to offer the required modulation formats.The calibration interval for any item of test equipment is important, and this is the case for any signal generator, whether it is new or a used signal generator. For example, when testing radio receivers it is necessary to test their susceptibility to out of band signals at image and other frequencies. As a result it is necessary to check the signal generator specifications to ensure that it has the required capabilities.Originally many signal generators had the capability to have amplitude modulation, AM , and frequency modulation, FM applied.
