+EVAL-CN0588-EBZ 
+===============
+
+DC to 10 kHz MEMS-Based IEPE Vibration Sensor
+""""""""""""""""""""""""""""""""""""""""""""""
+
+Overview
+--------
+
+The :adi:`CN0588` is a MEMS-based IEPE vibration sensor optimized
+for condition-based monitoring (CbM) applications. This solution has a
+constant current supply of 4mA and a DC voltage bias ranging from 
+around 8.75V to 14.75V.

+
+Since Piezoelectric sensors are predominantly used in CbM applications, IEPE
+is the de facto standard in CbM vibration sensing ecosystem. The IEPE
+interface, also commercially known as ICP, is a 2-wire protocol, signal and
+ground. In this protocol a data logger supplies a constant current via the
+signal line to the vibration sensor and the sensor modulates the voltage
+according to the measurand, typically between 10V to 30V. This reference
+design enables a direct IEPE piezoelectric sensor replacement with benefits of
+high bandwidth, temperature stability and ultralow noise MEMS accelerometers.
+This allows customers to easily evaluate an IEPE MEMS accelerometer solution
+for CbM applications on the same ICP piezoelectric sensor platform.

+Hardware Setup
+--------------
+
+Equipment Needed
+~~~~~~~~~~~~~~~~
+
+- EVAL-CN0588-EBZ
+- Current Source (e.g., Keithley 6220), or an IEPE-compatible DAQ such as the
+  :adi:`CN0582`, :adi:`CN0540`, :adi:`CN0579`

+
+Setting up the Hardware
+-----------------------
+
+.. figure:: eval-cn0588-ebz_setup0.png
+
+#. Mount the EVAL-CN0588-EBZ to the vibration shaker.
+#. Connect the SMA cable to the EVAL-CN0588-EBZ.
+#. Connect the other end of the SMA cable to the current source.
+#. Set the output constant current to 4 mA, and controlled voltage to 26V.
+#. Connect the BNC cable to the vibration shaker.
+#. Connect the other end of the BNC cable to the signal generator (output).
+#. Set the frequency settings to your requirement.
+#. The voltage of the current source is the output. Without an external
+   acceleration, the IEPE output should be around 12V.
+
+The EVAL-CN0588-EBZ is ready for experiment.

+#. By using SMA connector, connect the Piezo reference sensor of the vibration
+   shaker to Channel 0.
+#. Attach another SMA connector from the EVAL-CN0588-EBZ going to Channel 1 of
+   the EVAL-CN0582-USBZ.
+#. Power up the EVAL-CN0582-USBZ by connecting the Type C end of the USB cable
+   to the board and the other end to the host PC. 
+
+   .. tip::
+      The RED and GREEN LED should light up, indicating proper power up.
+
+#. Turn on the vibration shaker by plugging in the 19 V power supply.
+#. Ready the shaker by clicking the tune button. Two (2) green LEDs must light
+   up.

+      indicates successful firmware upload.
+
+#. Follow the installation prompts until the main window of the GUI appears.

+#. On the GUI dashboard, navigate to the left and click **‘Vibration Testing’**
+   to launch the window.
+
+#. Toggle ON the current source in the Reference & DUT Sensor Setup Section (5).
+

+   The CN0588’s IEPE interface makes it suitable to be used with different
+   IEPE-compatible data acquisition systems. Analog Devices has various IEPE
+   reference designs that users can readily evaluate and prototype with.
+
+   For CbM applications requiring one channel measurement, the 
+   :adi:`CN0540 24-Bit IEPE data acquisition system <cn0540>` is recommended.
+
+   For applications requiring Arduino form-factor, the :adi:`CN0579 <CN0579>` is
+   the suggested IEPE vibration sensor measurement system to use with the CN0588.
