This unit
The Keysight E3242A Charge/Voltage Breakout Box is a four-channel signal conditioning accessory engineered for integration with Keysight E1432A and E1433A VXI digitizer modules. It enables direct connection of charge mode accelerometers, voltage signals, and 4 mA constant current-powered accelerometers, eliminating the need for external transducer conditioning hardware in VXI measurement systems. Each channel provides dual input connector types
BNC for voltage and constant current input, and Microdot for charge mode accelerometers - supporting both acoustic and mechanical test applications. The E3242A implements programmable signal conditioning with a three-stage selectable gain charge amplifier, switchable 2 kHz low-pass filter, and software-controlled float/ground selection for input connector shells. The integrated 4 mA IEPE current source operates under program control with active status indication. All four channels deliver buffered BNC outputs for signal monitoring or external recording. Remote programmability via I2C control allows real-time adjustment of gain, filter engagement, current source activation, and grounding configuration through application software.
