Evaluate the Keysight 34470A 71/2 digit, Performance Truevolt/DMM and the Texas Instruments DAC8734EVM!
About the Keysight 34470A and BenchVue
The Keysight 34470A 7½ digit, Performance Truevolt DMM offer higher levels of accuracy, speed and resolution. Get more
insight quickly with Truevolt DMM's graphical capabilities such as trend and histogram charts, a data logging mode for easier trend analysis and a digitizing mode for capturing transients. Now, make measurements on your very low-power devices from an affordable DMM with a very low current range at 1 µA with pA resolution. The 34470A also has auto calibration to compensate for temperature drift so you can maintain measurement accuracy throughout your workday.
For PC or mobile device control, use the 34470A with the Keysight BV0001A BenchVue DMM Pro application. This software displays single measurements, charts, tables, or histograms from a single instrument or multiple DMMs simultaneously to correlate trends you might otherwise miss. Record measurements and export results in a few clicks, or access and control tests on your DMM remotely with the companion BenchVue Mobile app to monitor and respond to long-running tests from anywhere.
Basic application: instrument configuration, data visualization, 1 hour data logging, exporting data/screenshots
Pro application: in addition to basic features, adds histograms, digitizing and unrestricted data logging with limit checking and alerts
Supports 34401A, 34405A, 34410A, 34411A, 34450A, 34460A, 34461A, 34465A, 34470A

About the DAC8734EVM
The DAC8734EVM features the DAC8734 digital to analog converter. The EVM module provides a quick and easy way to evaluate the
functionality and performance of this high resolution serial input Digital to Analog Converter (DAC). The DAC8734EVM is designed to work by default for bipolar output range, but it can also be configured for unipolar output range by a simple switch change. The EVM provides the serial interface header to easily attach to any host microprocessor or TI DSP base system. Installed precision reference voltages of +5 VDC and +2.5VDC are selectable using onboard switches S2 and S3. REF5050 (+5.0 VDC source) and REF5025 (+2.5VDC) are pin compatible with the REF50xx family allowing a wide variety of reference values.
Terms & Conditions
For whome ever the lucky winners may be, I have been working on software for the DAC8734 Quad DACfrom TI and it is available for the Raspberry PI, Arduino and Launchpads (Ive tested it on a few). There…
Thanks for everyone who applied. We anticipate announcing the RoadTesters in the next few weeks. Given the complexity of this particular RoadTest, it will take a little bit longer to make the selections…
I will have a couple of blog posts that will follow the review (which I'm writing at the same time), that do go into depth more. One of the things I have been doing is comparing the sampling models of the 34470A against the older 34461A, which has involved the DAC being controlled by a raspberry pi, with both of the multimeters also being controlled by the pi via python scripts.
As far as data acquisition goes, I have used (and will show) both the data logging and digitising features - which are really nice and very useful.
Hopefully you will not be disappointed with my review - I will hopefully be uploading it very soon. I reviewed the 34461A as part of that RoadTest and I'm trying to top that review. Unfortunately, it is taking longer to write than I had hoped - 2 months is not a lot of time to review a piece of equipment like this (the 34461A review time was 3 months and the 34470A has more features, as well as the DAC and the BenchVue software).
Well you gave away 4 very nice meters and more than 2 months later you've had one provisional review and one that could best be described as perfunctory.
Whoa!!! Very cool!!! Time to start cleaning up one of the benches in my lab for this project. I intend to be fair and very thorough in my evaluations.
For those that didn't win, it looks like Dave is just getting started, and there appear to be some surprises that will be revealed next week, so stay tuned!
I'm going to go and have a celebratory beverage. Have a great weekend everyone!
