Now that 2014 is two weeks old (not counting New Year's day), test-and-measurement products are beginning to appear. Here are some of the products to come across my desk in the last two weeks. I expect to see many more new products in the coming weeks because DesignCon is coming in just 12 days.
On January 15, Yokogawa announced the PW8000, an oscilloscope dedicated to measuring power. Applications include motor and inverter testing, wind turbine power measurements, reactor-loss measurements on inverter boost circuits, transient responses for motors used in industrial robots, wireless charger power measurements, and measurements in power-distribution networks
Based on Yokogawa's ScopeCorder, the PW8000 accepts up to eight isolated voltage, current, or sensor input modules. That provides measurements on up to three AC mains power lines plus additional modules for other inputs. Sample rates are up to 100Msamples/s with bandwidth to 20 MHz, that's enough to capture transients and to view waveforms in the frequency domain to the 50th harmonic.
