Connect the RCal’s RF Out to the point in the path where the device under test (DUT) is when you take your actual measurements.

The screen displays type of calibration, frequency range, attenuation range, and number of points.

The Keysight signal analyzer preconfigures the interface.

Connect RCal’s RF Out to RF In of the signal analyzer.

Set the RCal options reference status as EXT (external).

Connect the signal analyzer’s 10 MHz reference signal to the U9361 RCal’s Reference In port.

Connect the RCal to your signal analyzer via a high-power USB port.

Keysight’s U9361 RCal receiver calibrator enables you to perform an accurate and reliable calibration for your spectrum analyzer / signal analyzers using the following steps: Learn more about the different types of spectrum analyzers here. This is because a swept-tuned analyzer uses a single narrow filter that is tuned across a range of frequencies to produce a spectrum display. A swept-tuned spectrum analyzer displays measurement results sequentially, in other words, not in ''real-time''. A real-time spectrum analyzer displays the energy at all frequency components simultaneously. How they process and display this information, however, varies with the specific type of analyzer. Both swept-tuned and real-time spectrum analyzers display amplitude versus frequency. Modern spectrum analyzers use digital signal processing to provide additional measurement capability and let you interpret measurement results much more easily. There are two broad categories of spectrum analyzers: swept-tuned analyzers and real-time analyzers.

WHAT ARE THE MAIN TYPES OF SPECTRUM ANALYZERS? A real-time spectrum analyzer captures transient and fast signals quickly.

WHAT IS REAL-TIME SPECTRUM ANALYZERS (RSA / RTSA)?Ī real-time spectrum analyzer first gathers data in the time domain and then translates it into the frequency domain by means of the Fast Fourier Transform (FFT). For more information refer to this blog: Spectrum Analysis Basics, Part 1 – What is a Spectrum Analyzer? The time-domain still provides useful information, such as the pulse rise and fall times of a signal, but the frequency domain allows you to determine the harmonic content of a signal, such as out-of-band emissions and distortion. Spectrum analysis uncovers sources of interference by displaying the spectral components independently. Without measuring in the frequency domain, the source and frequency of the second harmonic remain unknown. The time-domain measurement shows an impure sine wave. HOW DOES A SPECTRUM ANALYZER WORK?Ī complex signal in the time domain looks vastly different than in the frequency domain. Spectrum analyzers and signal analyzers perform measurements in the frequency domain to measure energy at each particular frequency. In other words, it is possible to transform a time-domain signal into its frequency-domain equivalent. Fourier theory tells us any time-domain electrical phenomenon consists of one or more sine waves of appropriate frequency, amplitude, and phase. In other words, we use the oscilloscope to view the waveform of a signal in the time domain. An oscilloscope enables you to view the instantaneous value of a particular electrical event (or some other event converted to volts through an appropriate transducer) as a function of time. WHAT IS THE DIFFERENCE BETWEEN AN OSCILLOSCOPE AND A SPECTRUM ANALYZER / SIGNAL ANALYZER? Refer to this Spectrum Analyzer and Signal Analyzer technical overview for more information. Signal analyzers measure both the magnitude and phase of an input signal at a single frequency. Spectrum analyzers measure the magnitude of an input signal versus signal frequency. WHAT IS THE DIFFERENCE BETWEEN A SIGNAL ANALYZER AND A SPECTRUM ANALYZER? A signal analyzer combines the superior dynamic range of a swept tuned spectrum analyzer with vector signal analyzer (VSA) capabilities and enables in-channel measurements like error vector magnitude (EVM) that requires both magnitude and phase information. WHAT DOES A SIGNAL ANALYZER DO?Ī signal analyzer measures both the magnitude and phase of an input signal at a single frequency.

For more information, refer to this Spectrum Analysis Basics application note for more information. Spectrum analyzers enable tests like noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance.
