 +The measurement time is dependent on a number of factors. Command transmission time, configured delays, source setup time, ADC acquisition time, count setting, averages, etc. Some factors, like the ADC acquisition time, are dependent on the frequency since the ADC needs to capture a minimum of three cycles of the waveform. Above 10 kHz, the acquisition time is constant. A typical single point measurement at 10 kHz with no averaging and delays disabled will take around 23 ms from ''z'' command being sent to the result being fully written back in the terminal. Each average will add around 4 ms. Each count will add about 13 ms.

 +----
 +==== Calibration Over Frequency ====
 +Starting in firmware version 1.2.2, calibration over frequency support is implemented. This means that all 16 gain settings can be fully calibrated at multiple frequency points. The process for calibrating over frequency is the same as single point calibration, except after running ''calibrate commit'' for the final gain setting at a given frequency, the user can then change the frequency and repeat the process. 
 +
 +When calibration is enabled, taking a measurement with ''z'' will automatically load the calibration coefficients with the nearest frequency from memory. After taking the measurement, running the command ''calibrate'' with no arguments will report the frequency of the coefficients that were used. For instance, if calibration was performed at 1 kHz and at 100 kHz, a measurement at 55 kHz would use the coefficients saved for 100 kHz.
 +
 +There are no restrictions on what frequencies the user can calibrate at. However, there are two hardware revisions of the ADMX2001B module; one has EEPROM for the nonvolatile memory (older) and the other has flash memory. Modules with the EEPROM can store 25 calibration sets at different frequency points before new sets start to overwrite the oldest ones. Modules with the flash can store up to 450 calibration sets. The command ''selftest run'' will report whether the module has EEPROM or flash installed.
 +
 +New commands have been added to facilitate calibration over frequency:\\
 +''resetcal'' (unchanged) will erase only the currently loaded calibration set from RAM.\\
 +''calibrate reload'' will load the nearest frequency calibration coefficients from the nonvolatile memory and store them in the RAM (taking a measurement implicitly runs ''calibrate reload'').\\
 +''calibrate erase'' will permanently delete all saved calibration sets from memory, restoring to the default configuration. This requires the password (default is Analog123) and cannot be undone!\\
 +''calibrate list'' will report all frequencies that have any calibration data saved (at least one gain setting).\\
 +''calibrate list <freq>'' will report what gain settings at a given frequency have been calibrated.\\
 +
 +The commands for reading and writing calibration coefficients detailed in [[eval-admx2001ebz#reading_and_writing_calibration_coefficients|Reading and Writing Calibration Coefficients]] apply to the currently selected frequency.
 +
 +==== Preloaded Calibration Sets ====
 +Version 1.2.2 also adds support for ADMX2001B modules to ship with a set of calibration coefficients intended to help with evaluating the board. Although the firmware supports it, boards that are currently shipping will not have calibration coefficients preloaded. This will be a future development. 
 +
 +Preloaded coefficients may not apply to a given test setup and their accuracy is not guaranteed. If the board came with them pre-loaded, then the below new commands apply:\\
 +''calibrate switch <evalkit/default>'' choosing evalkit will apply the preloaded coefficients. Choosing default will apply user generated coefficients. Generating calibration coefficients will automatically change the active set to default.\\
 +''calibrate'' with no arguments will report the active set.\\
 +The evalkit set cannot be modified or erased. Only the default (user) set should be modified or erased.

 +==== Trigger Input / Output Ports ====
 +The EVAL-ADMX2001EBZ has SMA terminals for the trigger input and output ports. These can be used to synchronize multiple modules or control measurement timing with an external instrument. To use the trigger input, the module must be configured to external trigger mode using the command ''trig_mode <internal/external>''. By default, the board is in internal trigger mode, and ignores pulses on the TRIG_IN port. Next, set the trigger count with ''tcount <count>''. This controls how many external triggers the module will respond to before exiting the WAIT_FOR_TRIGGER state. Now, type the command ''initiate''. The module will enter the WAIT_FOR_TRIGGER state. Most commands are disabled in this state. The module will automatically return to the IDLE state after receiving ''tcount'' triggers, or immediately if it receives the ''abort'' command. While in the WAIT_FOR_TRIGGER state, a software trigger can be provided with the command ''trigger'', in both internal or external trigger modes. If the trigger mode is external, then a 3.3V 15μs pulse (min) to the TRIG_IN port will be registered as a trigger. 
 +
 +When a measurement is initiated from the WAIT_FOR_TRIGGER state, either by an external trigger or software trigger, it will generate a 3.3V 15μs pulse on the TRIG_OUT port. 
 +
 +==== Digital Output Pins ====
 +The ADMX2001B features eight general purpose digital output pins, intended for controlling external MUXes or other peripherals. Support was added in version 1.2.2. The outputs can be accessed on pins 9-10 of P6, and pins 1-6 of P7. They can be set with the command ''gpio_ctrl <N>'' where N is a decimal from 0-255, and each of the 8 inputs are controlled by the respective bit for that position. Digital output 0 corresponds to the LSB. For instance, configuring ''gpio_ctrl 133'' (1000 0101 in binary) will set high P6 pin 9, and P7 pins 1 and 6.

 +**Board Programming Setup**
 +  - Connect the USB Blaster to the computer over USB and verify the driver installation
 +  - Plug the ADMX2001B module into EVAL-ADMX2001EBZ board
 +  - Connect the USB blaster to the port labeled "P8 JTAG" on the EVAL-ADMX2001EBZ
 +  - Connect the EVAL-ADMX2001EBZ to a 9V DC supply
 +  - Open the Quartus Prime Programmer
 +  - If the USB blaster is not selected in the upper hardware setup field (it will say No Hardware) then click "Hardware Setup..." and select the USB blaster. If it does not show up, then most likely there is an issue with the driver installation
 +  - Close the "Hardware Setup" window if it was opened, and verify the programming mode is set to "JTAG"
 +**Program the *.pof file**
 +  - On the left side of the main window of the Quartus Prime Programmer, click on "Add File"
 +  - Navigate to the location of the *.pof file. If it was downloaded using the installer from Analog.com, then the default folder will be ''C:\Analog Devices\Admx2001Firmware-Rel*.*.*\Firmware''
 +  - **See the image above carefully.** Check only the CFM0 and UFM boxes under "Program/Configure"
 +    - <wrap important> **IMPORTANT :** Do not check the top/parent box. If this box is checked, the board will not boot and will have to be returned/swapped </wrap>
 +  - Verify that the checked boxes match the screenshot above before proceeding
 +  - Click on the "Start" button
 +    - This operation takes several seconds to complete
 +    - Ensure the operation is successful by looking at the progress bar in the top right, and the messsages window at the bottom
 +    - Then, unplug the USB blaster, the firmware update is complete!
