This blog post is part of a collection, click here for links to the entire set, and a review of the products. Introduction The Agilent N9322C Spectrum Analyzer (SA) has some built-in capabilities to examine modulated signals. The post here examines Frequency Modulation (FM) analysis capabilities. The capabilities are useful for developing, testing and aligning FM systems.   The photo here shows a tone being transmitted using frequency modulation.   To see some more photos of the SA ...
A lot of times in my 20+ years of experience I came to the conclusion that very difficult problems that I worked on eventually narrowed down to just fundamental concepts.  This is the first blog post in a series focussed on fundamental concepts of electronic circuits analysis and design.  I will start with the most basic concept of electric current, after which I will present Ohm’s law from an intuitive perspective.  Following that I will talk about time varying electric cur ...
After playing with the Keysight N9322C for a few days I have garnered sufficient skill to make this full featured instrument reveal just a fraction of its capability.  A far more involved exploration will be posted in the Road Test review section, but for now, here is a quick illustration of just one very cool feature.   The TI CC11XL development kit comes with two TRXEB boards and several radio modules.  The pre-loaded firmware includes a mode that allows one board to send out a ...

Introduction Most test gear comes with remote connectivity options, and the Agilent N9322C Spectrum Analyzer (SA) is no different. It can be connected up via IEE-488 (available as an option) or via USB or Ethernet (available as standard). ...
This blog post is part of a collection, click here for links to the entire set, and a review of the products.   The review Keysight (was Hewlett-Packard, then Agilent, now Keysight) SA arrived today. I didn’t get much of a chance to try it out, but I did power it up and take a few photos (since they say a thousand words), until I examine it further. So this is not a review, just some glamour shots. The 640x480 display has a lot of detail and is nice, sharp, and is viewable from most ...
Dave Young of Young Circuit Designs is publishing a series of articles and videos on element14 every other week to describe his experience in upgrading from his trusty Tektronix TDS2024B to a new Tektronix MDO3104. See his other articles in the series: (a) Tek MDO3104 Scope Upgrade Series #1: The 70% Test with a Tek MDO3000 (b) Tek MDO3104 Scope Upgrade Series #2: Digital Decoding and Triggering for Analog Analysis (c) Tek MDO3104 Scope Upgrade Series #3: Trace Persist and Analog Triggering (d) ...
This tutorial was written along with this review that shows the connectivity features in action.   The Tektronix MDO3104 (and all MDO3000 series) scopes have a USB 'Device Port' and an Ethernet port on the back which allows the user to connect the scope to a computer, printer, or network. The Ethernet connection is very capable, enabling full remote control. The USB connection behaves exactly like the older scope GPIB connections which can be a handy feature in automated environments. Test ...
This tutorial was written along with this review that shows the connectivity features in action.   Tektronix's TDS2024B has a USB 'Device Port' on the back which allows the user to connect the scope to a computer or printer. It can be a handy feature, especially in automated environments. Test equipment is known for having poor user interfaces when it comes to connecting instruments, so this tutorial is intended to help out and encourage new users.   TDS2024B USB Functionality: Capt ...
While waiting for a calibrated microphone to arrive, I thought I'd try some simple audio spectrum tests using an Agilent 33622A and an Android spectrum analyzer app, called Speedy Spectrum, running on an Asus Nexus 7 tablet.  My intent was to play with a basic set up to get a sense of how the equipment I had at hand performed and to see if what I've read about psychoacoutsic mapping could be demonstrated in a simple and measurable way.  What came out of these exploratory tests was inte ...
My recent work with Dave testing Fluke Connect inspired me to take apart the Fluke 3000FC DMM.  I wanted to see the Bluetooth Low Energy (BLE) parts and see how much power BLE consumes in Fluke Connect.  In this post I try to reveal the good and the bad I find under the hood.    The enclosure is held together with just a handful of phillips screws.  There is nothing tricky at all about taking it apart.   Bluetooth and Antenna The Bluetooth Low Energy (BLE) ant ...
