The Yokogawa 701936 Deskew Correction Signal Source generates time-synchronized voltage and current signals for calibrating and eliminating skew in oscilloscope-based measurements. This precision instrument is essential for validating signal integrity in high-speed switching applications, including switched-mode power supplies (SMPS), miniaturized power supplies, and inverters. By providing accurate deskewing capability, it enhances the precision of switching-loss measurements and critical timing analyses.

– Key Features
Current Probe Support
Accommodates through-type CTs from AEM, LEM, and non-split core Hitec via removable wire loop. Compatible with clamp-on current probes including Yokogawa 701930 and 701931 models. Open design without enclosure allows accommodation of larger jawed clamps.
Voltage Probe Support
Accepts passive and differential probes for voltage measurement.
Deskewing Operation
Connects voltage and current probes to respective 701936 outputs and oscilloscope inputs. Engineers observe falling edges and use the oscilloscope’s deskew function to align signal start times, correcting propagation delay differences between channels.
– Compatibility & Integration
Oscilloscope Integration
Designed for Yokogawa oscilloscopes with Auto Deskew functionality:
• DLM2000 (firmware version 1.60 or later)
• DL6000/DLM6000 (firmware version 1.22 or later)
Probe Compatibility
Voltage probes (passive or differential) and clamp-on current probes connect to dedicated output terminals.
