A customer needs capture incoming satellite communication signals at a ground-based receiver. After analog demodulation and amplification, the signal is digitized by two 12 bit ADC chips clocked at a rate of 47.3 MHz. One ADC is used to scale a high-voltage input signal that has a mean value of 25.85 V. The second ADC chip is used to get better accuracy on the same signal, using a proprietary signal-scaling technique. The first ADC scales the full input voltage so that the second ADC only sees a small 50 mV signal around the mean 25.85 V. In this way, the combined system can achieve up to 22 bits of effective resolution. All ADC digital outputs are Transistor-Transistor-Logic (TTL). Products & Services
Analog-to-digital converter (ADC) chips transform information from analog to digital form.
Sample-and-hold amplifiers freeze analog voltage instantly. During this process the HOLD command is issued and analog voltage is available for an extended period.
Specialty data acquisition and converter chips condition signals or transform data (information) from one format to another, such from analog to digital.
Analog-to-digital converters (ADC) sample an analog signal and convert it to a series of digital values to represent the signal to a computer processor.
IndustryPack® modules are computer boards that interface with the IndustryPack (IP) mezzanine bus, a device used to provide input/output (I/O) capabilities in general-purpose computer systems. IndustryPack is a registered trademark of GreenSpring computers and a specification maintained by the VITA standards organization (VSO) of the American National Standards Institute (ANSI).
