+ | ====== CN0178 Evaluation Board Guide ====== | ||
+ | ===== Overview ===== | ||
+ | [[ADI> | ||
+ | |||
+ | The [[ADI> | ||
+ | |||
+ | The [[ADI> | ||
+ | |||
+ | The EVAL-CN0178-SDPZ board connects to ADI’s System Demonstration Platform (SDP) and is powered by a +6 V supply or +6 V “wall wart”. | ||
+ | {{ : | ||

+ | ===== Required Equipment ===== | ||
+ | * [[adi> | ||
+ | * [[adi> | ||
+ | * [[ftp:// | ||
+ | * 6 V or 6 V Wall wart | ||
+ | * //Agilent E3631A power supply// | ||
+ | * PC with the following //Minimum Requirements// | ||
+ | * Windows 7 (32-bit), Windows Vista (32-bit) or Windows XP | ||
+ | * USB interface | ||
+ | * RF signal source | ||
+ | * //Rohde & Schwarz SMT-03 RF signal source// | ||
+ | * Coaxial RF cable with SMA connectors | ||
+ | |||
+ | ---- | ||
+ | ===== General Setup ===== | ||
+ | ==== Block assignments ==== | ||
+ | {{ : | ||
+ | * The [[adi> | ||
+ | * The [[adi> | ||
+ | * Terminal block **J1** is the +6 V power supply | ||
+ | * Terminal block **J2** is the +6 V barrel connector for wall wart supply input | ||
+ | * Terminal block **J3** is the SMA connector for RF input | ||
+ | |||
+ | \\ | ||
+ | ==== Test setup ==== | ||
+ | {{ : | ||
+ | - Connect the 120-pin connector on the [[adi> | ||
+ | - Connect the RF signal source to the [[adi> | ||
+ | - With power to the supply off, connect a +6 V power supply to the pins marked “+6V” and “GND” on the board | ||
+ | *//If available, a +6 V "wall wart" can be connected to the barrel connector on the board and used in place of the +6 V power supply// | ||
+ | - Connect the USB cable supplied with the SDP board to the USB port on the PC | ||
+ | - Apply power to the +6 V supply (or “wall wart”) connected to [[adi> | ||
+ | - Launch the evaluation software | ||
+ | - Connect the USB cable from the PC to the USB mini connector on the SDP board | ||
+ | \\ | ||
+ | <WRAP center round important 60%> | ||
+ | Do **not** connect the USB cable to the Mini-USB connector on the SDP board before turning on the dc power supply for the **EVAL-CN0178-SDPZ**. | ||
+ | </ | ||
+ | \\ | ||
+ | |||
+ | ==== Calibration ==== | ||
+ | Because the slope and intercept of the system vary from device to device, a system level calibration is **required**. For this board, a 4-point calibration is used to correct for some non-linearity in the RF detector' | ||
+ | - Apply four known signal levels to ADL5902. Note that it should be well within the linear operating range of the device {{ : | ||
+ | - Measure the corresponding output codes from the ADC | ||
+ | - Calculate SLOPE_ADC and INTERCEPT calibration coefficients using the following equations: | ||
+ | * **SLOPE_1** = (CODE_1 - CODE_2)/ | ||
+ | * **INTERCEPT1** = CODE_1/ | ||
+ | - This calculation is repeated using CODE2/CODE3 and CODE3/CODE4 to calculate SLOPE2/ | ||
+ | - These will be used to calculate the unknown input power level, PIN, when operation in the field using the equation | ||
+ | * **PIN** = (CODE/ | ||
+ | - The observed code from the ADC will be compared to the calibration coefficient codes in order to retrieve the appropriate SLOPE and INTERCEPT calibration coefficients. | ||
+ | * Example: If CODE from ADC is between CODE1 and CODE2, then SLOPE1/ | ||
