Keysight / Agilent E3243A / E3242A Breakout Box

  • Integrates 4 Channels of Signal Conditioning
  • Applications Include Both Acoustic and Mechanical Measurements
  • Two Input Connector Types Per Channel
  • Reduces the Count of Transducer Conditioning Equipment Needed for Both Small and Large Channel-Count VXI Systems


Agilent E3243A
The Agilent E3243A Microphone/Voltage Breakout Box accessory is specifically designed to interface microphones (as well as voltage and 4 mA constant current power supply accelerometers) to Agilent’s high performance E1432A and E1433A VXI Digitizer modules. It integrates 4 channels of signal conditioning in one box, reducing the count of transducer conditioning equipment needed for both small and large channel-count VXI systems. Applications include both acoustic and mechanical measurements. It has two input connector types per channel to match the intended transducer connection, as well as buffered outputs via BNC connectors for signal monitoring or recording. The E3243A is dedicated for use with the E1432A and E1433A only and is designed for acoustic measurements by providing the conditioning necessary for pressure and free field microphones. It also provides conditioning for mechanical measurements where voltage or 4 mA constant current power supply accelerometers are to be used. Input connections for each channel are via BNC for voltage and 4 mA constant current power supply, and a 7-pin LEMO connector for microphones. The E3243A is remote programmable allowing you to set up each channel’s parameters through your application software. Each channel can be programmed for float or grounded input which connects the BNC shell to chassis ground, or allows for a differential input. Other programmable functions include gain setting and 4 mA constant current power supply on/off control.

Agilent E3242A
The Agilent E3242A charge/voltage breakout box is an accessory for the E1432A and E1433A VXI Modules. This Breakout Box provides both BNC and Microdot connection for each channel of the VXI module. Each breakout box has four BNC and four Microdot connectors for signal input. A 26-pin connector is provided for connection to the VXI module through an extension cable. Each channel has a program controlled float/ground switch to connect the input connector shell to the chassis ground, or to allow a floating input. The charge input has a charge amplifier with three gain settings, and a 2 kHz low-pass filter that can be switched in or out through software control. The BNC input is a direct connection to the VXI module with no amplification. The IEPE current source for powering accelerometer transducers can be switched on or off under program control. A light indicates when the current source is on.

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!
