Integrals come in handy in measuring power consumption when that consumption is intermittent or corresponds to a dissipation vs. time function that is irregularly shaped. The classic example is that of a controller that wakes up every second or so. You can, of course, use single-shot capture to get the current waveform when the controller […]
Automotive Ethernet test software covers BroadR-Reach, 100Base-T1 and 1000Base-T1 formats

Newark element14 to handle E36300 Series triple output power supplies from Keysight
Newark element14 is now stocking the E36300 Series Triple Output Power Supplies, the latest product from Keysight’s general purpose bench power supplies range. The E36300 Series is said to be one of the quietest power supplies on the market with low output ripple/noise and accurate voltage/current measurement. Key features include an easy-to use front panel […]
Proof-of-parameter test leads experts to formally request NB-IoT standard revision for transceivers
While designing a narrowband internet of things (NB-IoT) terminal transceiver, experts from Hong Kong Applied Science and Technology Research Institute (ASTRI) discovered an improper definition in the NB-IoT standard’s receiver wideband intermodulation requirement. The requirement was more stringently specified than that in the LTE standard, which runs counter to the promise of offering low-cost/low-power NB-IoT […]
The modern economics of renting test instruments
The development of online instrument exchanges puts a new wrinkle into how to get the optimum use of test gear. LEE TESCHLER EXECUTIVE EDITOR When a project comes up that involves expensive test gear like gigahertz-range signal analysis, statistics from the Equipment Leasing & Finance Foundation show this kind of instrumentation is increasingly acquired through […]
Photo gallery: Here’s what happens during Keysight’s Test-drive 2017
Instrument maker Keysight is conducting what it calls a North American test-drive tour at 30 cities in the U.S. and Canada this spring. We sat in during the stop in Cleveland, Ohio. Here’s what we saw.
MIL-STD 1553 bus: Making measurements and connections
MIL-STD-1553 was first used by the US Air Force in 1973 to define a serial data bus for military aircraft, notably the F-16 Fighter. It soon began to be a means of moving data in many other US military jets, as well as in domestic and foreign avionics, showing up even in the Russian MIG-35. […]
Measuring the Universal Serial Bus (USB)
The average person on the street, computer literate since childhood, is familiar with the look and feel of a USB cable and is generally aware of the difference between types A and B plugs that go into host and peripheral ports respectively. It is also common knowledge that specialized cables with mini and micro plugs […]
Channel emulator tests LTE-LAA and HetNet small cell instrumentation
Highlights: New capabilities in Propsim F32 channel emulator enable efficient performance testing of devices and network equipment with LTE-LAA and HetNet small cell technology support The enhanced Propsim F32 allow users to assess all existing, as well as planned, LTE-LAA Carrier Aggregation and Wi-Fi-offloading field deployment scenarios Keysight has developed new LTE-Hi test scenarios, in […]
Calibration Services handle PXI gear from multiple vendors
Instrument maker Keysight Technologies, Inc. says it will now handle equipment from other instrument vendors at its One-Stop Calibration Services. Keysight says the reason for the move is that modern test systems often integrate instruments of different form factors from multiple vendors, including PXI and AXIe instruments used with traditional benchtop instruments. These instruments are […]
