Keysight / Agilent E1330A / E1330B Quad 8-bit Digital Input / Output Module

  • 1-Slot, B-size, VXI Module
  • Quad 8-bit Input or Output Data Ports
  • Wide Variety of Output Data Types


The Agilent E1330A and E1330B Quad 8-bit Digital Input/Output module are B-size, 1-slot, register-based VXI devices. They have a four-port digital input/output module intended for data communication and digital control.

Each 8-bit port is identical consisting of data and handshake/control lines. Each 8-bit port can be configured for output or input and positive or negative true logic. Ports can be combined allowing data transmission using bytes, words (16-bit), and long words (32-bit). Bit data transmissions are also allowed. Three handshake and control lines are provided for each port when using SCPI programming. The flag line from each of the individual ports can be used independently, or they can be combined when using word or long-word data transmission.

Notes from the Agilent website:

What is the difference between an E1330A and an E1330B?
NOTE from E1330A/B Operator Manual: The interrupt circuitry for the E1330B is implemented as release on interrupt acknowledge (ROAK). The Digital I/O modules will de-assert (or release) the interrupt request line during an interrupt acknowledge cycle.

The interrupt circuitry on the E1330A was implemented as release on register access (RORA). The E1330A digital I/O module would continue to assert the interrupt request line until the Port Control/status register on the digital I/O module is accessed.

The E1330A is the only (RORA) VXI card that Agilent Technologies created. The reason that the E1330B changed to (ROAK) was so that it would be the same as all other Agilent Technologies VXI cards.

Both the E1330A and E1330B may be used with command modules E1300A/E1301A,E1306A and with the E1405A/B and E1406A. The commands are the same for both the E1330A and E1330B.

Direct backplane control using C-SCPI, ISCPI in SICL, and plug and play drivers do not work with the E1330A. C-SCPI, ISCPI in SICL, and plug and play drivers all require ROAK thus only the E1330B is supported when using these drivers.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
