| Calibrate the gain setting (0, 1) at 100kHz with a resistor of value 1k Ohms. The true resistance Rt from the E4980A at 100kHz was measured as 1000.019 Ohms, and the true reactance Xt was 0.822 Ohms. | Calibrate the gain setting (0, 1) at 100kHz with a resistor of value 1k Ohms.

| Calibration coefficients for each gain can be read to the terminal, and written back to the device. This allows the user to save coefficients for multiple different test setups, conditions, or frequencies. | Calibration coefficients for each gain can be read to the terminal, and written back to the device.

| 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, | Starting in firmware version 1.2.2, calibration over frequency support is implemented.

| - | === Preloaded Calibration Sets === | + | ==== 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. | 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.
