Power Limiters
-
Keysight's power limiters provide the best broadband input protection from excess RF power, DC transients and ESD, for a variety of RF and microwave instruments and components. For example, the input circuitry of spectrum analyzers, network analyzers, frequency counters or amplifiers can be protected from unintentional inputs up to 5 watts average power. At even greater power levels, failure mode for the limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage.

Attenuators And Pulse Limiters
-
A bidirectional attenuator, i.e. the attenuation and power capability specification is valid for both directions. There is a large variety of applications for this attenuator: The measuring range of a spectrum analyzer can be increased. Any kind of meter can be protected against overload; it can be used to control the linearity of a meter reading. It can minimize measurement uncertainty caused by mismatched impedances. During an EMI receiver calibration an attenuator directly at the pulse generator output is inevitable.

Handheld spectrum analyzer/Signal analyzer
-
Recently, a lot of equipment have taken the high frequency or microwave technology according to the advancement and the spread of the telecommunication equipment. As a result, the handheld spectrum analyzer to analyze the signal by the frequency domain is necessaries now. The handheld spectrum analyzer is roughly classified into a heterodyne method and a Fourier transform method. The heterodyne method is also called the swept frequency method and makes it possible to measure up to tens of GHz though only for the steady signal. On the other hand, the Fourier transform method is also called the real time method and can handle an unsteady signal though the low measuring frequency range up to tens of MHz. As for our spectrum analyzer or signal analyzer, the MSA300/400 series adopts the swept frequency method, and the MSA500 series adopts both the swept frequency method and the Fourier transform method.

The two in the set included micro probes are used to measure low-frequency magnetic fields up to 1 GHz, e.g. at signal conductors (150µm), SMD componets (0603-0201) or IC pins. The MFA micro probes are guided by hand. An amplifier stage is integrated into the probe head. The amplifier stage (9V, 100mA) is powered via the BT 706 Bias tee. It has an impedance of 50 Ohm. The micro probes are connected via the Bias tee to a spectrum analyzer or an oscilloscope. The MFA 02 set delivery of Langer EMV-Technik GmbH includes correction lines. With the help of the correction lines the probe output voltage is converted either into the respective magnetic field or to the current which is running through the conductor.
