The 701262 ScopeCorder module enables synchronous measurement of voltage and temperature for applications requiring correlated electrical and thermal analysis.

The module features isolated universal voltage input with 16-bit resolution and supports signals up to 42 V peak (DC + AC). Voltage waveforms can be captured at up to 100 kS/s, allowing observation of transient and switching behavior. The anti-aliasing filter prevents high-frequency components from distorting the measured waveform during sampling, improving measurement accuracy.

Temperature measurement is supported at up to 500 S/s, with compatibility across a wide range of thermocouple types.

By acquiring voltage and temperature data on a common time base, the 701262 simplifies evaluation of system behavior in power electronics, battery testing, and design validation applications.
