Probe aids high-voltage scope measurements
Test & Measurement World Staff - September 17, 2012
Yokogawa’s Model 701927 high-speed differential probe allows high-voltage floating signal measurements using the company’s DLM2000 series of mixed-signal oscilloscopes and other instruments equipped with a Yokogawa probe interface. The Model 701927 has a 3-dB bandwidth of DC to 150 MHz and measures differential or common-mode voltages up to ±1400 V DC plus AC peak or 1000 V RMS.
To simplify use, the probe features automatic attenuation detection and obtains its power through the Yokogawa probe interface. Input attention ratio is switchable between 50:1 and 500:1. CMRR (common-mode rejection ratio) is –80 dB at 60 Hz and –50 dB at 1 MHz.
The Model 701927 can be used in the mechatronics, automotive, and power electronics sectors for testing such devices as motors, power supplies, and inverters. A 1-m-long extension cable supplied with the probe allows it to be used in thermostatic chambers or for measurements on large or hot devices.
