Learn What An Oscilloscope Is, How To Choose The Correct One, & Properly Take Care Of It

Oscilloscopes test, measure and display voltage signals. Signals are plotted on a graph to demonstrate how the signal changes over time. Oscilloscopes provide reliable results over an extensive period of time and are used in a variety of industries ranging from healthcare to automotive. Health care workers use oscilloscopes to monitor a patient’s heartbeat and to observe brain waves. Physicists and other research scientists use oscilloscopes to track tiny particles and to analyze the impact of various signals such as mobile or television. Engineers and electronic technicians use them the most out of any occupation. Electronic and electrical engineers rely on them for designing electrical equipment. Sound engineers use oscilloscopes to observe vibrations in engines and computer design engineers use them to determine processor speed and frequency. Even automobiles advance to incorporate more electronic equipment each year and need oscilloscopes to troubleshoot automotive issues. There are many oscilloscopes to choose from. To choose the best option for the application, consider the bandwidth, input channels, sample rate, record length, vertical resolution, and other various features. The bandwidth needs to capture all frequency components of the signal. A good rule of thumb is the bandwidth should be greater than 5x the highest signal frequency. More input channels increase awareness around what’s going on in the design. Mixed signal oscilloscopes offer both digital and analog channels to increase visibility. The faster the sample rate, the greater the wavelength resolution. This helps ensure critical information isn’t lost. It is recommended that the sample rate is greater than 5x the highest frequency component to capture all signal details. Record length is the number of samples stored in a single acquisition. Due to storing a limited number of samples, the waveform duration is inversely proportional to the sample rate. A longer record length allows for a longer duration to be captured at high resolution. Vertical resolution is greatly important when converting a signal from analog to digital. Higher bit converters capture and measure more detail. Taking into consideration the different features of an oscilloscope compared to what needs to be measured should lead to the right choice. Due to the extreme sensitivity of an oscilloscope and the importance of reliable results, professional calibration services are imperative to the quality of the equipment. When purchasing an oscilloscope, most of the time it comes calibrated and ready to use. After about a year it is time to have it professionally calibrated. This assures the user, the measurements recorded are accurate and within specification limits. Equipment may need to be tested regularly to be in compliance with specific standards. An oscilloscope that is out of tolerance will result in false information when a product is measured. Your oscilloscope may need to be calibrated more or less than a year. Calibration intervals should take into account the accuracy of the instrument, the impact an out of tolerance oscilloscope would have on the process and the instruments performance history. Analyzing the calibration reports should give insight into this information. Grand Rapids Metrology would be happy to help you determine which oscilloscope best meets your application, and we’ll care for it every year after your purchase. We work with the purpose to uphold quality standards and want to ensure your measurements are accurate. SOURCES: Oscilloscope Functions Oscilloscope Industries Oscilloscope Calibration

Customer Service From Our Technician’s Perspective

Recently, a Senior Service Technician at Grand Rapids Metrology, Shayn Wyman, shared a message with his fellow employees. It was so powerful and explained the company’s ideals so well, we decided to share it with you!

Written by Shayn Wyman –

Customer service is defined as “The assistance and advice  provided  by a company to those people who buy or use its products or services.”

With that being said, each and every one of us has the ability to impact the relationships we have with our current and potential customers on a daily basis.

Whether it is a face-to-face sales encounter, a technician showing up to a customer site, or simply answering a phone call – we all have an obligation to make each and every customer feel like they are the most important person we service. It should be that way because, without our customers, we wouldn’t go very far in this or any other industry.

We all have to be passionate when it comes to customer service. Have you ever had a bad day and brought it with you to work? Sure, we’re all guilty of that from time to time. But how will that frame your performance and our company to a customer? Even on a bad day we still need to strive to be enthusiastic, take pride in our work, demonstrate a drive to succeed, all the while hold ourselves accountable for our performance in front of others.

We must also exhibit integrity to show our customers the loyalty and reliability of GRM employees. We must conduct ourselves in a moral, ethical, and trustworthy manner to prove to our customers that we are a driven, disciplined and proactive organization in all that we do.

Sometimes in order to be a team player, we have to make a conscious decision to serve the greater good of the company, fellow employees, and our customers – even when those actions don’t serve our own personal best interests.

Always be respectful and optimistic, skillful in our positions, and level-headed in our decision making, while being properly presentable even when it may be a difficult decision.

Customer service is what keeps our customers coming back. Don’t give someone reason not to want to continue doing business with GRM.

Here’s to servicing our customer to the best of our ability each and every day at Grand Rapids Metrology!
