When a detailed analysis of signal frequency is needed, ATEC offers a wide array of spectrum analyzer rentals at affordable rates from top manufacturers like Keysight, Rohde & Schwarz, Anritsu, and Tektronix.
What is a Spectrum Analyzer?
A spectrum analyzer is an electrical device that measures the amplitude or strength of a signal against the device's full frequency range. The spectrum analyzer provides details of the frequency spectrum and the strength of known and unknown signals.
Every electronic device gives off an electrical signal and a tool is needed to measure those signals without emitting its own noise or frequency. The spectrum analyzer is a passive receiver that collects and displays signal data.
As opposed to an oscilloscope, a spectrum analyzer measures in the frequency domain rather than time. The instrument displays how complex signals work at each frequency level and all related harmonic content. Along with signal strength, which is measured in decibels (dBm), the device tests for the following RF measurements:
- Noise
- Frequency
- Modulation
- Harmonic Spurs
These measurements help reveal the performance or any issues with the RF spectrum. That might include occupied bandwidth, harmonic distortion, output power, third-order intermodulation, signal stability, and many other key details.
How to Choose the Best Spectrum Analyzer Rental
Starting as simple signal analyzers, the spectrum analyzer has improved and branched out with modern technology. But how can an engineer be sure which device is right for the job?
Consider these specifications and options before choosing a spectrum analyzer to rent:
Resolution Bandwidth (RBW)
Some signals require analysis over a wide resolution bandwidth, while others need a smaller RBW for a precise frequency resolution. A smaller resolution bandwidth also increases the sweep time (taking more measurements) to analyze a signal with greater detail.
Frequency Range
While many devices offer a large frequency range, it's key to choose the spectrum analyzer rental that has the ideal top and bottom frequency limit. To properly view any distortions or harmonics, the top limit should be much higher than that of the signal being measured.
Amplitude and Frequency Accuracy
One number or percentage can't detail the accuracy of a spectrum analyzer. Instead, frequency readout accuracy covers specifications like span error and RBW center-frequency error.
Amplitude accuracy also plays a vital role in spectrum analyzer performance. Both absolute and relative measurements of the amplitude rely on limited uncertainty. The ideal spectrum analyzer rental will often require a compromise between display fidelity errors and IF-gain uncertainties.
Swept-tuned or Real-time?
The swept-tuned or superheterodyne spectrum analyzer is the traditional model. True to the name, these analyzers downconvert the signal and sweep it throughout a frequency range. These models do offer a wide bandwidth and frequency range but are unable to measure phase.
The real-time spectrum analyzer (RTSA) is a modern development that works more like an oscilloscope. These instruments collect signal data in the time domain, then use the Fast Fourier Transform (FFT) to convert info to the frequency domain. An RTSA constantly observes the frequency spectrum, measuring phase, and better finding the small or hidden interferences.
Spectrum Analyzer Rental Rates
Considerations like frequency range, size, functionality, and many other factors can contribute to pricing, but in general, buying a reliable spectrum analyzer can cost tens of thousands of dollars.
So, how much does it cost to rent a spectrum analyzer? Whether at a biweekly, monthly, or even 6-month rate, rental is a fraction of the purchase price. And no need to worry about calibration—before shipping out any equipment, ATEC ensures all devices are properly calibrated and ready for use upon arrival.
