Data acquisition

• Record and display fast sweeps of waveform data to disk with up to 400 million data points per sweep with a Power1401-3A or towards 10 million with a Micro1401-4
• Output pulse, sine, ramp and stored waveforms while sampling
• Generate sets of varying stimuli on up to 8 waveform and 16 digital outputs
• Set up multiple output states, each providing differing pulse outputs or stimuli. Sequence the order and repeats of each state cyclically, randomly, semi-randomly, manually or to a predefined protocol. Frames are marked with the state used
• Sample multiple waveform inputs at aggregate rates up to 1MHz
• Easily switch sampling configurations or output protocols
• Capture free-running or triggered sweeps with post or peri-trigger modes
• Gap free option for acquisition of continuous data

• Trigger data capture from external pulse, waveform threshold crossing or internal clock
• Sample variable numbers of points in different sweeps
• Tag frames to indicate state or artefacts for selective review and analysis
• Perform built-in and custom analyses on incoming sampled data
• Configure software controllable amplifiers including the CED1902 low noise isolated pre-amplifier, the Digitimer D360, D360R and D440 isolated patient amplifiers, and the Power1401 gain option
• Automatically adjust channel scaling in response to gain changes detected from either patch clamp amplifier telegraphs or supported software controlled amplifiers
• Simultaneously review earlier frames together with incoming data using duplicate windows
• Easily view last measured values, measured differences, timers and output state flags in scalable windows with large font
• Sample at arbitrary or varying rates with external convert input option
• Sample data from third-party devices using CED Talker software modules

System requirements

For sampling, Signal version 8 requires a CED Micro1401 or Power1401 intelligent laboratory interface and a PC with Windows 7, 8, 10 or 11, or Intel Macintosh running Windows, and supports 64-bit versions of Windows. The computer must be modern enough to support the SSE2 instruction set. We recommend a minimum of 8GB of RAM. Signal dynamic clamping requires a CED Power1401-3, Power1401 mk II or Micro-4 intelligent laboratory interface.

Both 64-bit and 32-bit OS versions are supplied; either version can be used on systems running a 64-bit OS. See the compatibility table. When installed on a 64-bit system the 64-bit version provides a performance increase and access to more memory.
