Power Measurement with a Spectrum Analyzer attenuator

Power Measurement with Spectrum Analyzer

Use the Spectrum Analyzer to measure the signal produced by a signal generator. Equipment Required For Power Measurement Signal Generator Spectrum Analyzer Variable Attenuator Couple Of Cables For Interconnection Safety precaution Before starting remember that overloading a device like the power meter may become cause of damages.  Always estimate the power you are going to […]

Decreasing the Frequency Span Around the Signal 1

Decreasing the Frequency Span Around the Signal Using Spectrum Analyzer

Using the Spectrum Analyzer signal track function, you can quickly decrease the span while keeping the signal at center frequency. This is a rapid way to take the closer look at the area around the signal to identify signals that would otherwise not be resolved. This procedure uses signal tracking and span zoom to view […]

Reducing Input Attenuation On Spectrum Analyzer

The ability to measure a low-level signal is limited by internally generated noise in the spectrum analyzer. The measurement setup can be changed in several ways to improve the analyzer sensitivity. The input attenuator affects the level of a signal passing through the instrument. If a signal is very close to the noise floor, reducing input […]

Resolving Small Signals Hidden by Large Signals On Spectrum Analyzer

In this method uses narrow resolution bandwidths to resolve two input signals with the frequency separation of 155 kHz and the amplitude difference is of 60 dB. Step 1.   Connect two Signal Generators as sources to the Spectrum Analyzer Step 2.   Set one Signal Generator to 300 MHz at −10 dBm Press Frequency, […]

Resolving Signals of Equal Amplitude on Spectrum Analyzer

A decrease in resolution bandwidth is used in the combination with the decrease in video bandwidth to resolve the two signals of equal amplitude with the frequency separation of 100 kHz. Observe that the final RBW selection to resolve the signals is the similar width as the signal separation, while the VBW is a little […]

Comparing Signals Not On Same Screen Of Spectrum Analyzer Using Marker Delta

Comparing Signals Not On Same Screen Of Spectrum Analyzer Using Marker Delta

You can measure the frequency and amplitude difference between two signals that do not appear on the screen at one time using Spectrum Analyzer. This technique is useful for harmonic distortion measurements tests when narrow span and narrow bandwidth are required to measure the low level harmonics. In this method the spectrum analyzer used 10 […]

Comparing Signals On Spectrum Analyzer Using Marker Delta Pair

Using the Spectrum Analyzer you can used to measure 10 MHz signal, frequency and amplitude differences between two signals on the same screen using the analyzer delta pair marker function. (First 3 steps are the same a in “Comparing Signals On Spectrum Analyzer Using Marker Delta“procedure) Step 1.Preset the analyzer: Press Preset button or Factory […]

Comparing Signals On Spectrum Analyzer Using Marker Delta

Comparing Signals On Spectrum Analyzer Using Marker Delta

Using the Spectrum Analyzer you can easily compare frequency and amplitude differences between the signals. The analyzer delta marker function allows you to compare two signals when both appear on the spectrum analyzer screen at same time. In this procedure Spectrum Analyzer use 10 MHz signal to measure the frequency and amplitude differences between the […]
