Description
The Agilent E1418A is a C-size, 1-slot, register-based VXIbus module that provides 8 or 16 fully independent, isolated or non-isolated 16-bit digital-to-analog (D/A) conversion channels. It generates precise analog voltage and current signals for automated test equipment (ATE) and multi-channel instrumentation racks.

Integration and Field Deployment Notes
When integrating the E1418A into legacy VXI mainframes (such as the Agilent E8403A or E8404A), ensure the chassis power supply budget accounts for the module’s power draw, which scales up to approximately 49 W in 16-channel isolated configurations.
The module supports register-level programming for fast backplane execution rates. Output mode configuration (voltage versus current) is established via physical jumpers on the terminal block or through register commands. For in-situ calibration, use the built-in CALBUS terminal in conjunction with an external 5.5-digit multimeter via software commands, eliminating the need to physically pull the module from the VXI rack.
Frequently Asked Questions
Can the channel count be upgraded in the field?
Yes. Modules can be expanded using hardware option kits such as the E1524A (8-channel non-isolated expansion kit) or E1525A (8-channel isolated expansion kit), provided physical slot and cooling capacity are available in your VXI chassis.
What interface options are available for field wiring?
The module accepts a standard screw-terminal block, with optional crimp-and-insert or ribbon cable connector kits available depending on the specific ordering option (e.g., E1418A-A3E or E1418A-A3H).
Is this module compliant with current environmental regulations?
No. The E1418A has reached end-of-life (EOL) status with the manufacturer and is restricted from sale or import in regions enforcing strict RoHS directives (such as the EU). It remains widely supportable in legacy defense, aerospace, and industrial test environments via secondary markets.
