Signatec has released the SIG-PRG series, a portable high-speed data acquisition and waveform-generation system.
The SIG-PRG series combines the features of oscilloscopes, spectrum analysers and signal generators with high-speed RAID storage to create an advanced turnkey wideband signal test system.
The SIG-PRG system lets users record and play back continuous analogue signals with no break in the signal record at its peak 400MB/s data rate.
It features two analogue signal-recording channels at up to 160MHz sampling rate, two analogue IandQ waveform generation channels at up to 1GHz sampling rate, 16-bit resolution for the A/D and D/A channels and an analogue capture bandwidth from 100KHz to 600MHz.
Signatec's SIG-PRG system allows for multiple terabytes of continuous signal data-capture, enabling optional embedded custom real-time processing and providing high dynamic-range data at up to 16 bits of resolution.
Other benefits include data-analysis software for viewing captured data, as well as client/server capabilities that allow the systems to be easily controlled either directly from the embedded computer or from an existing user's network computer.
The SIG-PRG provides a complete, intact signal data record for all narrow-band channels within the greater captured spectrum.
Signatec's SIG-PRG is ideal for IF signal data-capture and operates by grabbing a single large band of data at up to 80MHz bandwidth for 16-bit data.
The standard SIG-PRG operating mode for spectrum analysis can record all raw-signal data, perform periodic snapshot FFT processing and display the processed results.
Signatec also offers options for real-time processing to perform digital down conversion (DDC) on selectable frequency bands in the greater spectrum as well as fast Fourier transform (FFT) on all captured data, with both raw and FFT data results recorded.
Options also exist for users to program custom processing routines into the embedded FPGA onboard the SIG-PRG's signal recording module.
Signatec's SIG-PRG waveform-generation module can play simple and repetitive waveforms.
It also has more advanced arbitrary waveform-generation capabilities for creating unique waveforms for terabytes of data samples.
This signal-generation component is especially useful for playing back into analogue from previously digitised analogue signals from the SIG-PRG's signal-recording module.
