Processing Overview and Capabilities
GSA 6000 provides various options for signal processing: FPGA, GPU, and CPU-based processing.
FPGA-based Processing
At the heart of the GSA 6000 are four industry-leading Altera StratixTM IV FPGA’s. These core processing elements combined with Guzik’s implementation of customer-specified measurement algorithms provide end users with a truly tailored measurement solution where speed and throughput count. Once processed, results can be streamed via the GSA’s PCI Express interface to a host computer at sustained data rates up to 8.8 Gbyte/sec. 
The FPGA-based processor combined with Guzik’s custom engineering capabilities provides you with the possibility to perform digital signal processing directly in GSA prior to sending waveform data out to computer. Many applications may require only processed results to be sent to the host computer rather than raw waveform data. Guzik will work directly with customers to implement custom processing capabilities drawing from years of experience in waveform analysis. Channel equalization, filtering, FFT, DFT, min/max, averaging, and parameter calculations among others are all available along with applications-specific requests. Guzik can provide custom services after a technical consultation regarding the specific application and required processing.
The combined FPGA processing resources are listed in the table below:
| Processing Block | Number | Notes |
| Logic Cells | 562,400 | 1 LUT and 1 flip-flop |
| Block RAM |
3,800 80 |
9-Kbit blocks 144-Kbit blocks |
| Multipliers | 3680 | 18-bit x 18-bit multipliers |
Table 2. FPGA Resources
Information about the GSA 6000 available options:
| Firmware Option | Description |
|
ADC_BASE (Digitizer Base License) |
Base license for one segment simultaneous acquisition and readout of data to the host computer, with patented4 digital Time-Interleaved ADC mismatch, frequency response and phase equalization. See white paper Equalization of Multiple Interleaved Analog-to-Digital Converters (ADCs) |
|
ADC_SM (Segmented Memory Acquisition) |
Multi segment acquisitions in the Guzik digitizers use a circular acquisition buffer with minimum inter-segment dead-time of 300ns. This allows, for example, to capture up to 64 million repetitive signals with relatively large repetition intervals and better utilize the already large acquisition memory by discarding dead-time in between signals. Down to femtosecond resolution time-tagging allows to know the precise time between each captured waveform segment. Please refer to GSA SDK User’s Guide section 5.1.2 Acquisition Format Specification |
|
ADC_BB (Low-pass filtering and decimation) |
Digital low-pass filter (LPF) is used to reduce the analog bandwidth of the digitizer. It has an adjustable bandwidth of 6.5 GHz and down to 125 MHz. If the input signal bandwidth is lower than the digitizer’s analog bandwidth, then a filter with a lower cutoff frequency can be applied to improve SNR and ENOB. Since the cutoff frequency is lowered, decimation by powers of 2 is performed. Decimation reduces sampling rate, therefore reduces the data speed to store data to the onboard memory and to transfer data to the host computer. It also extends the acquisition time proportional to the decimation factor. |
|
ADC_BBRT1 (Real-Time 10 GSa/s Baseband Filtering) |
To increase acquisition time for longer signals, which have smaller analog bandwidth than the digitizer, the Real-time 10 GSa/s baseband digital filtering and decimation option can be used to reduce acquisition data and increase ENOB before storing it to the memory. This option enables triggered streaming and recording of up to aggregated 1.25 GSa/s or 500MHz of baseband with the GSA6044 across all channels together with the segmented memory option. Trigger/gate resampled at 250 MHz. Please refer to GSA SDK User’s Guide section 5.7 Performing Data Streaming |
|
ADC_DDC (Digital Down Converting) |
In Guzik digitizers the Digital Down Conversion DDC is implemented using FPGAs. The data from ADC is transferred to the memory and from memory through digital equalizer to DDC. The down conversion is implemented by two multipliers with Sin/Cos LO signals. Down converted signals are connected through LPF/decimator to I/Q memory and transferred to PC. Keysight 89600 VSA software can be used to tune each digitizer channel center frequency independently and can perform final processing and measurements related to particular transmission standard for measurement channels simultaneously. This method significantly reduces the amount of data transferred to PC and in return increases measurement speeds. Please refer to GSA SDK User’s Guide section 5.8 Performing Digital Down Conversion |
|
ADC_DDCRT1 (Real-Time 10 GSa/s Digital Down Converting) |
The Real-Time 10 GSa/s Digital Down Conversion option allows to perform the down conversion in real-time in the GSA6044 digitizer FPGAs. Real-time IF Magnitude triggering can be used to decide if data is to be stored to the digitizer I/Q memory or not. This allows to capture and store only signals of interest within the DDC span and reduces the data amount needed to be transferred to the PC for post processing. Keysight 89600 VSA software can be used to tune each digitizer channel center frequency independently and can perform final processing and measurements related to particular transmission standard for measurement channels simultaneously. Please refer to GSA SDK User’s Guide section 5.9 Performing Digital Down Conversion in Real Time |
|
ADC_AVG (High Speed Deep Averaging) |
Averaging for noise reduction is used in measurements when high dynamic range is required. Averaging is done in real-time in FPGAs thousands of times faster compared to other methods. With the 40-bit 640K internal accumulator the accuracy of measurements is greatly increased by allowing up-to 4 billion averaged waveforms. This allows viewing side bands spectral regrowth and other repetitive signals previously hidden in the noise. Please refer to GSA SDK User’s Guide section 5.6 Performing Real Time Accumulation Measurement |
| ADC_AVGS (Bundles ADC_SM and ADC_AVG)(High Speed Deep Segmented Averaging) |
Segmented averaging mode further advances the measurement flexibility by utilizing groups of data of interest into segments. Each segment may either have its own trigger event programmed or just suspend the data accumulation process for specified period of time. Please refer to GSA SDK User’s Guide section 5.6 Performing Real Time Accumulation Measurement |
|
ADC_M128 (128 GByte Acquisition Memory Option) |
Capture the longest time spans at full sample rate with an acquisition memory upgrade to 128 GByte. Longer time capture at full sample rate provides superior acquisitions to hunt down those difficult to find problems in applications with mixed analog and digital signals, serial busses, or various communication signals. Please refer to GSA SDK User’s Guide section 4.4.3.1 Input Resources Configuration |
|
ADC_SYNC1 (Multi-Module Synchronization Capability) |
Multi-module synchronization capability, allows to increase the total number of digitizer channels by combining multiple modules into one instrument. The new option enables multichannel phase coherent time-tagged input channels to be triggered from common source or independently. Synchronization is performed during digitizer initialization and channel-to-channel skew is restored between instrument channels. The digitizers can be setup to follow an external 10 MHz or 50 MHz time base without uncertainty, which is critical for ATE and OEM systems application. Please refer to GSA SDK User’s Guide section 4.5 Synchronization of Several Digitizers and 5.1.17 Synchronous Acquisition |
