When I hear someone say this and I ask “why,” the answer is nearly always “I need to measure how much power this thing is using”.  Based on this experience I have come to consider current probe use as synonymous with power measurements. Usually someone is trying to figure out how much power they are using or determine if the supply they have… (Show more)

In urban slang, signal-to-noise ratio (SNR) is a simple enough concept: the ratio of useful to useless information. We all know people whose SNR is not as high as we might hope. Unfortunately there’s no technology yet available to boost their SNR. So engineers can be happy that’s not true for RF signals. We can now extend SNR in wideband… (Show more)

Many oscilloscope users measure current flowing through a circuit by measuring the voltage drop across the current sense resistor. But if you’re lucky enough to have a Keysight N2820A high-sensitivity current probe, it is even more than that. While the N2820A (and N2821A) is designed to measure low level current signals with high sensitivity,… (Show more)

Do you want to accurately measure signals with minimal effects from your oscilloscope probe? The oscilloscope probe is a critical link in the quest for accurate signal measurements. The probe is more than just a connection between the circuit under test and the oscilloscope. It can affect both your measurement results and the circuit under test.… (Show more)

Performing parametric measurements on digital modulation is often required to ensure reliable wireless transfer of data, such as secured financial transfers. One example gaining acceptance in today’s mobile technology industry is Near Field Communication (NFC). Most of today’s newer smart phones come standard with NFC technology. It won’t be long… (Show more)

Previously, I wrote about the hardware comparison between the Keysight S-Series oscilloscopes and the Rohde & Schwarz RTO2000 oscilloscopes. In that review, we saw that the S-Series offered better hardware with much higher ENOB and lower noise, you can read the full article here.  Excellent hardware is nice, but you are probably also looking at… (Show more)

What is USB Type-C? USB Type-C is a USB specification for a small 24-pin reversible-plug connector for USB devices and USB cabling.  It supports 10 Gbps data rates, with a path to 40 Gbps, and can source or sink up to 100 Watts (5 Amps at 20 Volts).  In ALT mode it supports DisplayPort, HDMI, MHL, Thunderbolt, and it is possible to support other… (Show more)

Check Back Daily for Scope Giveaways and Special Offers! It’s November, and many of you know what that means – we are getting close to the largest online shopping day of the year, Cyber Monday. But what would be better than Cyber Monday?  We didn’t want to limit great offers to just one day, so we have been hard at work developing Keysight’s… (Show more)

In today’s world, it is hard to buy a really bad oscilloscope. But how do you choose the very best oscilloscope, especially when messaging and datasheet specs look so similar between different vendors? I’m here to give you an insider view on the differences between the Keysight S-Series oscilloscopes and the Rohde & Schwarz RTO2000 oscilloscopes. … (Show more)

By Rachel Beddor The surge in low-speed serial buses in the consumer market has brought about the need for accurate protocol decoders. Traditionally, decoding a serial bus would mean a trip back to your introductory engineering class— lots of counting 1s and 0s. This method is tedious and prone to errors, so a better option is to use technology to… (Show more)
