Upcoming software release unleashes the N7900 APS’s potential without any programming

Our N7900A Advanced Power System (APS) is well named, being the most advanced power product we’ve introduced to date. In many ways it is based on our N6700 series modular DC power system and N6705B DC power analyzer, incorporating their capabilities, including:

• High precision programming and measurement
• Seamless measurement ranging
• High speed measurement digitization of voltage, current, and power
• Long term data logging of voltage, current, and power
• Output ARB and List capabilities
• And quite a bit more

In addition the N7900A APS brings quite a few new and unique capabilities as well, including:

• Much greater output power
• Logic-configurable expression signal routing for advanced custom triggering and control
• Optional external dissipater unit for full two quadrant operation
• Optional black box recorder for post-test diagnostics when needed
• And quite a bit more

To take advantage of these advance capabilities does require a bit of programming, which is to generally be expected for an automated test environment, but in low volume design validation and R&D this can slow down the desired quick time-to-result. The N6705B DC Power Analyzer, in Figure 1, has a full-featured front panel menu and graphical display that lets design validation and R&D users quickly configure and run complex power-related tests on their devices. In comparison, the N6700 series, pictured in Figure 2, does not have all the front panel capabilities of the N6705B and can be looked on as the ATE version of this product platform, requiring programming to take advantage of its advanced capabilities. The N6705B shares all the same DC power modules that the N6700 series uses.

The N7900A APS is very similar in form and function to the N6700 series, not having all the advanced front panel capabilities that the N6705B has for bench-friendly use of its advanced features. I am really pleased to be able to share with you that this is now changing! While we are not creating a bench version of the N7900 APS, we are upgrading our 14585A Control and Analysis software, which emulates the front panel of an N6705B and more, to work with the N7900 APS as well. The 14585A will soon let you quickly and easily create and configure complex power-related tests based on using the N7900 APS.  I am fortunate enough to be working with a beta version of the software. Some examples of things I was able to do in just a few minutes were to capture the inrush current of an automotive headlight, shown in Figure 3, and superimpose an AC sine wave disturbance on top of the DC output, shown in Figure 4.

The updated release of the 14585A Control and Analysis software is just a few weeks away. More about the 14585A software can be found by clicking on the following link <14585A>. With the 14585A being a great way to implement ideas and tests quickly, using the N7900 APS, look for me and others coming up with some interesting applications in future posts here on “Watt’s Up?”!

Keysight Technologies – What’s in a name, anyway?

This is an exciting time for us! Yesterday, January 7, 2014, we learned what our new company name will be: Keysight Technologies. Here is a link to the official press release: 

http://www.agilent.com/about/newsroom/presrel/2014/07jan-gp14001.html

If you have not heard by now, back in September of 2013, Agilent Technologies announced it would split into two companies by the end of 2014. Since I started in 1980, 33+ years ago, I have worked for and will continue to work for the electronic measurement side of the business. For my first 19 years with the company, we were Hewlett-Packard, a company that formed in 1939 as a test and measurement company and eventually birthed Silicon Valley. It is this electronic measurement side of the business that is getting the new name, just as we did in 1999 when we became Agilent from Hewlett-Packard. The other part of Agilent, the life sciences, diagnostics, and applied markets side will continue to operate under the Agilent name. Note that the electronic measurement side will still have the same great people designing and supporting the same great products and services….just a new name: Keysight Technologies.

So let’s take a closer look at the new name, logo, and tagline for Agilent’s electronic measurement business:

The name combines the words “key”, meaning essential, and “insight” meaning intuitive perception. Essential intuitive perception. Seeing what others cannot. A key can also be used to unlock something; we will continue to unlock measurement insights, as our tagline says. And we have been doing this for 75 years - since the day that Bill Hewlett and Dave Packard released their first electronic test instrument, an audio oscillator, in 1939. By the way, it is purely a coincidence that the Watt’s Up? authors, Ed, Matt, and I have combined experience of more than 75 years as stated in our blog header, although I’d like to think that the three of us have been unlocking measurement insights in the AC and DC power field for a combined total of 75 years! In fact, we now have a total of more than 80 years’ experience between the three of us and I will update the header later this year when we officially begin using the Keysight name. But I digress...

The logo symbol is derived from one of the most fundamental wave shapes there is: a sine wave – a wave shape from which all other wave shapes can be built. This is very appropriate for our 100% focus on electronic measurement, not to mention a tribute to our original founders, Bill and Dave, for their audio oscillator. And the power products and topics that you read about here in Watt’s Up? are equally represented by the logo symbol, especially our AC sources! If you really think about it, Keysight will be doing what Hewlett-Packard originally set out to do and Agilent continued to do for decades: build the world’s leading test and measurement company.

So what’s in a name? Essential intuitive perception is in our name. A clear focus on electronic measurement is in our name. Our strong and deep heritage is in our name. And when we begin to fully operate as Keysight Technologies later this year, what you will find behind our name will be the same high quality products and people that you have come to know. That’s what’s in the name Keysight Technologies!
