What is pulse generator

Pulse Generator Basics

Pulse generators are used to provide the pulses for use in the variety of electronic applications. Typically pulse generators will provide a number of functions and capabilities: Rectangular Wave Generation As the name implies the pulse generator is designed to produce pulses that are rectangular in nature, often capable of driving logic circuitry, although they […]

Multichannel Pulse Generators

Multichannel Pulse Generators

Some of the later pulse generators are what are termed multichannel pulse generators. These multichannel pulse generators can produce several channels of pulses with independent pulse widths and delays with independent outputs and even independent polarities. These pulse generators are often used for synchronizing, delaying, gating and triggering multiple devices often with respect to a […]

Multimeter Safety Precautions | Electrical Safety

Most tests using a multimeter involve low voltage and resistance, both of which can’t hurt you much. But sometimes you may need to test high voltages, such as the input to an AC-operated power supply. In a case such as this, careless use of the multimeter can cause serious bodily harm. Even when you’re not […]

volt-ohm Multimeter What is VOM

volt-ohm Multimeter | What is VOM?

The multimeter, also called a volt-ohm meter (or VOM), is the basic tool for anyone working in electronics. You use a multimeter to take a variety of electrical measurements hence the term “multi.” With this one tool, you can You Can Measure From Multimeters Measure AC voltages Measure DC voltages Measure resistance Measure current going […]

5000 Series Oscilloscopes

What is an Oscilloscope?

Oscilloscope is a basic electronic test instrument that is used to observe the electronic signal in graphical shape, typically voltage with respect of time. that is why Oscilloscope is time domain instrument. In other words it is a voltage versus time plotter. Oscilloscopes has two basic types, older one is analogue and now latest versions are in digital. Oscilloscope support various features […]

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 […]

Decreasing the Frequency Span Around the Signal 1

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 […]

Signal Generator to the Spectrum Analyzer

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 […]
