Berkeley Nucleonics is introducing the fastest sampling transient recorder available. The Model 1134 Transient Recorder features a 14-Bit design with blazing sample rates. Each 1U Rack Mount unit provides 4 channels of sampling at rates up to 2GHz. The signal bandwidth may be up to 300 MHz.

Data acquisition at high speeds is parsed into 3 phases:

1) Data Acquisition – Here the analog input signal is continuously sampled at a preset sampling frequency. The settings are stored safely in analog memory. A single trigger signal initiates a memory condition whereby the sampling is paused and memory is stored. At this point in time, the previous 2520 data samples are stored in memory.

2) Digitize and Store – When Data Acquisition stops, the samples stored in an analog memory in the Model 1134 are read out rapidly and translated to digital data over 14 bits. The data is then stored in event RAM. The end of the conversion to digital triggers is recognized by the system and a flagged in an internal register.

3) Read Out – The data from the RAM may be read out via the acquisition system. This operation lasts a few mS for the full readout of a 4-channel recorder. The fast readout speeds allow acquisition frequency close to 100 Hz for readouts of 2520 points for each active channel.

BNC-Flex Software

BNC-Flex is a flexible interface for your PC to address the Model 1134. The software package is included at no charge with the instrument and allows remote or automated testing. Development of test routines may be simplified with the use of scripts to manage BNC-Flex.

BNC-Flex includes “Scope”, a friendly Oscilloscope-Display mode with fast refresh rates and four simultaneous channels.

“Scope” is an efficient way to view a simultaneous display of the entire waveform and, if horizontal zoom is enabled, a selected segment of the acquired waveform at the same time. This allows detailed analysis and review. The zooming ratio is defined with the horizontal cursor.

AutoSave is a mode for monitoring events and automatically storing them to disc in ASCII on set triggers. Time and Date stamps are included in the data log.

BNC-Flex Advanced Modes
  • Average & Infinite - To ‘persistence modes’ useful for long term acquisitions and long periods of data monitoring. This is a valuable tool for glitch monitoring or other extended analysis.
  • Digital Filtering – An update on recent installations, this mode gives users additional filter options. Low-Pass, High-Pass, Band-Pass and Band-Stop Filters are all included in the current BNC-Flex release.
