The reference design includes the device data capture via the JESD204B serial interface and the SPI interface. For more information on synchronization please refer to A Test Method for Synchronizing Multiple GSPS Converters. The design of the board is specifically tailored to synchronizing multiple AD-FMCADC4-EBZ boards together. ADI provides complete source (HDL and software) to re-create those projects (minus the IP provided by the FPGA vendors, which we use), but may not provide enough info to port this to your custom platform. This board is targeted to use the ADI reference designs that work with Xilinx development systems. If you want a commercial, ready to integrate product, please refer to one of the many FMC manufacturers and the FMC specification (ANSI/VITA 57.1). Although this board does meet most of the FMC specifications, it’s not meant as a commercial off the shelf (COTS) board. The board meets most of the FMC specifications in terms of mechanical size, mounting hole locations, and more. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the AD9680 is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications, such as radar and jamming/anti-jamming measures. This product is designed for sampling wide bandwidth analog signals up to the second Nyquist zone. All clocking and channel synchronization is support on-board using the AD9528clock generator. The FMC form factor supports the JESD204B high speed serial interface. The AD-1 sells for $2,799.99 and can be purchased from D’Amore Engineering or with a 4-6 week lead time for delivery.The AD-FMCADC4-EBZ is a high speed 4-channel data acquisition board featuring two AD9680 dual channel ADC at 1000 MSPS and four ADA4961 low distortion, 3.2 GHz, RF DGA driving each converter. The AD-1 allows your staff to quickly dispel misinformation and educate consumers on the spot utilizing the equipment in their own vehicle! In addition, the AD-1 will quickly prove to be the most valuable tool in your installation bay by allowing your installation staff to quickly and easily outline the correct course of action to get any audio system performing to its peak. This is particularly useful when used in conjunction with a sine wave generator, like the hand-held IM-SG, to analyze the frequency response of any audio system. Meters Mode – the AD-1 can be used as an AC voltmeter that measures in dBV (decibel Volts). In addition, this prevents the end user from over-driving their system and damaging equipment. Measured power approximates the clean “RMS” power the amplifier is capable of delivering on music peaks.ĭD-1+ Mode – The AD-1 can be used to setup a system’s gain structure allowing the user to precisely set amplifier gain overlap, thereby delivering the best compromise between the noise floor and dynamic range capability of the audio system. Measured power is clean “RMS” power.ĭynamic Power Mode – The AD-1 uses industry standard tone bursts and captures the power generated during these bursts.

This is useful for amplifier designs that are inherently noisy, like inexpensive Class D offerings and head units.

Uncertified Mode – The AD-1 uses patent pending technology that ignores harmonic distortions and noise and detects clipping that approximates 1.0% distortion. The AD-1 Amplifier Dyno has five modes of operation:Ĭertified Mode – The AD-1 utilizes the patented DD-1 Distortion Detection System to measure the maximum power at 1.0% harmonic distortion. The AD-1 is simple to operate via its menu driven control panel.
