DI-1120 Data Acquisition Starter Kit

Description

DI-1120 USB Data Acquisition starter kit with Windaq software. Features 4 differential analog input channels, 14-bit measurement resolution, and a full scale range of ±2V to ±100V.

Model DI-1120 delivers premium analog performance at a surprisingly affordable price. Four analog input channels provide differential measurement flexibility and programmable ranges per channel of ±2, ±5, ±10, ±20, ±50, and ±100 V full scale. The differential input configuration provides noise rejection, easily adapts to single-ended signal sources, and is protected to 120 V rms so that inevitable measurement mishaps will not harm the instrument. The front end feeds a variable resolution, 14-bit ADC that ranges from 12 to 14 bits as a function of sampling rate. Lower sampling rates deliver higher resolution readings. The maximum sampling throughput rate of the DI-1120 is 160 kHz, providing 12 bits of resolution. Below 40 kHz the instrument provides 14-bit measurement resolution. Rounding off the analog subsystem are low-pass filters per channel with automatic corner frequency selection as a function of sampling rate. All these features combine to provide pure data acquisition power at an unmatched price point.

The DI-1120 provides 7 digital ports, each configurable as an input or a switch. Input protection is provided to 25 V. When activated as inputs two ports allow dual functionality as discrete inputs, or can be programmed as a counter or rate input respectively. The rate input features a 50 kHz maximum measurement, allocated over twelve programmable measurement ranges (10 Hz to 50 kHz full scale.) The counter input provides 16-bit resolution and a terminal count value of 65,535. The discrete, counter, and rate inputs are members of the same internal scan list used by the analog input channels. This means that all enabled elements are acquired synchronously, which allows meaningful comparisons between analog and digital channels. For example, the rate input measuring engine speed allows rpm data to be acquired in lock-step with analog data. Configured as a switch a digital port can be used to control external loads up to 25 V @ 100 mA, and the switch can be controlled asynchronously during scanning.
