The Agilent 34461A has several connectivity options - LAN and USB, by default, with GPIB available as an option. This blog post will detail my experience with using both LAN and USB. Unfortunately, I do not have any equipment that uses GPIB, however, the use of GPIB is decreasing, partly due to the cost of the equipment and cables, and partly because both LAN and USB are much more readily available. For example, it is much easier to connect two devices to a LAN than run GPIB cables in between th ...
The Agilent 34461A provides many different connectivity options, USB, LAN and GPIB (as an optional extra), which means that it should easily fit into a modern lab or test system. For test systems, it is likely that custom software will be written to control the entire system, however, for a lab this is often not the case, relying on the manufacturers software. Agilent provide two connectivity utilities to do this, the first is meant for Windows computers and the second is meant for the Apple iPa ...
I was originally planning to show the use of the multimeter in a tutorial style, however, the multimeter is very easy to use and I feel that a tutorial approach is likely to seem, and be, patronising. So this blog post is just going to focus on practical measurements that can be done with the 34461A. Microcontroller current consumption The power consumption of modern microcontrollers can vary quite a lot, with many of them stating that they have very low power modes. I thought that it would be ...
The Agilent 34461A is a 6.5 digit multimeter designed as a replacement for the 34401A. It improves on the specifications of the 34401A and, most noticeably, includes a 4.3 inch display instead of the 34401A’s vacuum fluorescent display (VFD). Specifications Rather than copying the datasheet (which can be found at http://cp.literature.agilent.com/litweb/pdf/5991-1983EN.pdf), I will provide a quick summary: DC/AC voltage - 100 mV to 1000 V DC/AC current - 10 uA to 10 A Resistance - 100 Ω ...
