Product Features

4 or 8 Analogue Input Channels
With a fixed ±10 V full scale range.
Differential Analogue Input Configuration
Enhanced noise immunity.
Anti-alias Filter per Analogue Channel
Reduces the risk of acquiring meaningless, aliased data. Corner frequency automatically selected at one-tenth of the sampling rate.
Armoured Inputs Absorb Mistakes
Analogue inputs are protected to ±50 V and digital inputs up to 25 V.
Fast, 220 kHz Sample Throughput Rate
Stand-alone Data Logger Operation
Store data to flash drives at throughput rates up to 160kHz. (Unlock Code required to record all channels to USB thumb drive.)
12- to 16-bit ADC Resolution
Seven Digital Ports
Folds discrete I/O into the measurements process. Each bit is programmable as an input or as a switch.
Rate Measurement Channel
Counter Channel
Pre/Post Tigger Storage to USB Memory
Set trigger levels to record up to 2G (combined) of pre- and post-trigger data (total file size of 4G).
Software Support
Provided with ready-to-run WinDaq software – records up to four channels. (Unlock Code required to record all 8 channels using WinDaq.) Also supplied with documented command protocol for OS-independent use.

Supplied with: a 6-foot USB cable, a screwdriver for signal connections, an NIST-traceable Calibration Certificate, and a 32GB USB flash drive with WinDaq software.
