7GHz differential probe matches Rigol’s top-end Oscilloscopes
https://www.electronics-lab.com/7ghz-differential-probe-matches-rigols-top-end-oscilloscopes/
Rigol has created a 7GHz differential probe to go with the 5GHz DS70000 oscilloscopes that it announced at the beginning of the year. Called PVA8000, the probe also comes in a 3.5GHz variant, and there are single-ended types. Inside is the same ‘Phoenix’ ASIC that the company designed for the scopes. “As soon as you […]
Robust high-bandwidth passive DIY probes
https://www.electronics-lab.com/robust-high-bandwidth-passive-diy-probes/
Tomi Nihtilä build his own high-bandwidth passive probes to solve some issues with classic oscilloscope probes he describes on the article. He writes: Before presenting this great tip I must admit I did not come up with this idea. This type of measurement probe is presented in the book High Speed Digital Design – A […]
IkaScope – a new wireless oscilloscope probe
https://www.electronics-lab.com/ikascope-new-wireless-oscilloscope-probe/
ikalogic.com launched “IkaScope” a new wireless oscilloscope probe that is able to make measurements directly on your mobile phone or your laptop. IkaScope transfers measured signals over high speed wifi connection and it will remember your home or office access points. It will work with iOS, Android and Windows devices (OSx will also be supported). […]
High-performance scope probes top out at 20 GHz

Tektronix, Inc., the world’s leading manufacturer of oscilloscopes, introduced the P7700 series of TriMode™ probes for use with Tektronix performance oscilloscopes. Offering up to 20 GHz bandwidth, the new probes ease the challenges designers face when debugging circuits found in the latest mobile and enterprise designs by minimizing probe loading, improving access to smaller, more-densely […]
An almost-GHz active differential oscilloscope probe
https://www.electronics-lab.com/an-almost-ghz-active-differential-oscilloscope-probe/
Christer wanted to see how a 500MHz differential clock was behaving so he decided to build an active probe. To simulate the circuit he used TINA spice software and documented the process in three parts on his website. What I really wanted was an active differential probe which should be able to look at […]
Building a simple Circuit Probe
https://www.electronics-lab.com/building-a-simple-circuit-probe/
Vicente Jiménez has published a new project. It’s a circuit probe that gives an indication when a node is floating or driven logic high or logic low and can also be used as a continuity tester. He writes: Sometimes you need to check one circuit and test some of its nodes. Usually a tester in […]
RF Probe

m0xpd @ m0xpd.blogspot.com has build a RF probe on a little PCB board. Today I finally got round to building a nice little RF probe kit from Rex, w1rex, the Tuna King over at QRPme. RF Probe – [Link]
Teardown & analysis of a Keysight InfiniMax III N2802A 25GHz active probe
https://www.electronics-lab.com/teardown-analysis-of-a-keysight-infinimax-iii-n2802a-25ghz-active-probe-2/
A teardown & analysis of a Keysight InfiniMax III N2802A 25GHz active probe from TheSignal Path: In this episode Shahriar takes a close look at one of Keysight (Agilent) InfiniMax III active probes. The model N2802A offers 25GHz of analog bandwidth, 17.5pS of rise time and a total differential input capacitance of 32fF at 10k-Ohm […]
Compensation of Oscilloscope Probes
https://www.electronics-lab.com/compensation-of-oscilloscope-probes/
by Maurizio @ dev.emcelettronica.com: Using simple wires to measure signals with the oscilloscope would result in unreadable plots on the scope, the main reason being the noise coupled onto the “probe” itself. The first line of defense against that would be to use a coaxial cable as a probe, which would prevent external noise coupling. An unwanted […]
