Agilent E1418A 8/16-Channel D/A Converter
Data Sheet
Features
* 1-Slot, C-size, register based * 8/16 independent channels, flexible and configurable * Individual isolation per channel * 16-bit resolution D/A per channel * Programmable selectable voltage/current modes * Software controlled calibration
Description
The Agilent E1418A 8/16-Channel D/A Converter is a C-size, 1-slot, register-based VXI module. It consists of 8 or 16 fully independent, isolated or non-isolated, 16-bit D/As. Each channel can be set to voltage or current mode with local or remote sensing on voltage outputs. All outputs can be updated with registerlevel programming to allow fast backplane access. Each channel can be updated individually, or by using the internal data buffer, synchronized so that all channels change simultaneously. The channel output mode is set with jumpers in the terminal block for each channel or by register programming. Each D/A converter can be calibrated without removal through software commands and use of the terminal block CALBUS in conjunction with a 5.5-digit multimeter. The on/off terminal block has standard screw terminals for field wiring. Refer to the Agilent Technologies Website for instrument driver availability and downloading instructions, as well as for recent product updates, if applicable.
Fast Updates
All outputs can be updated with register-level programming to allow fast backplane access. Rates are limited by controller speed and analog settling time. Each channel can be updated individually, or by using the internal data buffer, synchronized so that all channels change at the same time. The channel output mode is set with jumpers in the terminal block for each channel or by register programming.

In-place Calibration
Each D/A converter can be calibrated without removal through software commands and use of the terminal block CALBUS in conjunction with a 5.5-digit multimeter. In addition, a built-in self-test command provides a high level of confidence that the module is operating properly.
AC Output
Choice of Connectors
The easy-to-use on/off terminal block, a feature of QUIC, comes with standard screw terminals for field wiring. Optional crimp and insert or ribbon cable connectors are available. Each channel contains a programmable output disconnect relay to open or close the channel.

General Characteristics
Settling time: Isolation: Synchronization: 300 s (+ full scale to - full scale step, single channel, to rated accuracy) 42 Vdc/ac peak (channel-to-chassis or channel-to-channel) Software commands, external trigger inputs, or TTL backplane trigger lines provide a choice of synchronizing event. Each individual channel can be updated by software command or all channels can be updated at the same time based upon a software or hardware trigger.
