Spectrum Analyzer Probe
Here is a homebrew spectrum analyzer you can build using an old vcr tuner module.
Spectrum analyzer probe. 2 1 1 probe solutions for r s spectrum analyzers a difficulty using active probes with spectrum analyzers is that power needs to be supplied to the probe to drive the built in amplifier. Now we connect a 1 5ghz passive probe rigol rp6150 passive probe to the input of the spectrum analyzer. But the probe i have is a common oscilloscope probe rigol rp1100 which has the common 1x and 10x options. Hi everyone i am using a spectrum analyzer with the input impedance of 50 ohm.
Frequency coverage will be from around 80 mhz to 920 mhz and varies slightly with tuner manufacturer. The primary use is to measure the power of the spectrum of known and unknown signals. And what could be the solution for. The adapter converts the probe plug of an r s active probe to a standard n connector.
It lacks the features that make the expensive ones a delight to use. It will also require an old oscilloscope that is capable of x y mode with dc input and a receiver which can tune around 47 mhz am and can also be modified to tap. This application note provides information on how to use oscilloscope probes in rf measurements using spectrum analyzers and show the results of differential. However spectral compositions of other signals such as acoustic pressure waves and optical light waves.
So would using this probe effect my measurements and how please explain. A sensor coil with a turn or two on it connected to the spectrum analyzer by a meter or two coaxial cable. A new product from smith design looks like a fat scope probe but actually works as a 1 100 mhz spectrum analyzer. From portable usb spectrum analyzers to benchtop real time spectrum analyzers tektronix has the solution to meet your rf analysis.
For use in r d for wireline and wireless communications aerospace and defense industries as well as high speed pcb design and validation work. Using oscilloscope probes is a possibility to perform measurements by connecting to printed circuit board lines and chip contacts where only a minimal area is required to make contact. A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.
The rp6150 is designed to be a 10 1 probe when connected to 50 ohms. Keysight offers an innovative family of rf probes that are engineered for in circuit test measurement that can be used with signal spectrum analyzers signal source analyzers and network analyzers. To connect probes to spectrum analyzers r s offers the probe adapter rt za9. A spectrum analyzer measures the amplitude of an input signal versus frequency within the full frequency range of the instrument.
