Description
The Hioki U8975 4CH Analog Unit is a high-speed, isolated input module designed to capture and analyze high-speed phenomena with precision. Featuring a sampling rate of 5 MS/s and 16-bit A/D resolution, this 4-channel unit delivers accurate, high-resolution measurements. With a maximum rated voltage to ground of 300 V AC/DC (CAT II), the U8975 ensures safety and reliability in demanding testing environments.
Compatible with Hioki’s Memory HiCorder MR6000 and MR8740T, the U8975 is ideal for capturing transient signals and high-speed events across multiple channels. Its isolated input design enhances measurement accuracy and versatility, making it indispensable for research, development, and diagnostics.
Simultaneous measurement of multiple channels
The MR6000 can simultaneously measure up to 32 channels, while the MR8740T can measure up to 108 channels at a time.
The U8975 accepts direct input of up to 200 V DC across 4 channels. With a sampling rate of 5 MHz (across a frequency band of 2 MHz), high speed, and 16-bit resolution, it can perform multi-channel, high-speed, and high-resolution measurement.
Comparison Table
This is a comparison table against the discontinued 8946 4-channel analog unit. Please refer to this table when you consider replacement.
*The 8946 cannot be used with current memory HiCoders (MR6000 series, MR8847A series, MR8827, MR8740/41, and MR8740T).
