1. Full signal (10V) at Nyquist frequency resolves to 12 bits at 1.25 (1.00) MHz input, 2.8 (2.0) MHz output, and to 16 bits at 650 kHz input, 500 kHz output [() refers to multi-channel rate]. Measured max small-signal rate = 1.5 MHz input/output. Multi-channel crosstalk = 11 bits at 1.33 MHz.

2. Input operates at 500 kHz at all signal levels. Output operates at 200 kHz for +/-10 V signals and 500 kHz for +/-100 mV signals.

3. Software licenses are single-computer licenses, and permit operation on one computer system at a time.

4. Multiple software licenses receive a 25% discount on 2nd and additional licenses for all products except direct-to-disk I/O.

5. I/O boards provide a maximum analysis bandwidth equal to 50% of the board's sample rate.

6. Except where noted, I/O boards can sample multiple channels at a per-channel sample rate = (total sample rate) / (number of channels). Thus a 500-kHz board can acquire 2 channels at 250 kHz per channel.

7. I/O boards do not contain anti-alias filters (AAF's), except where noted. AAF's may be necessary during acquisition or playback, depending on signal bandwidth and sample rate.

8. I/O panels with 8 input channels are available by special order.

9. The PCMCIA desktop adapter card allows PCMCIA analog I/O cards to be operated in a desktop and requires one PCI slot.

10. RTS 5 provides scrolling, measurement and editing of unlimited-length sound files and can exchange measurements and signals with SIGNAL. Live scrolling sound acquisition and playback will be added to the RTS in the future.

5. First generation (1996 or earlier) Dart PCMCIA I/O cards may require a hardware upgrade for compatibility with Windows 2000/XP. Contact Engineering Design to determine if your card requires an upgrade.

6. For security key upgrade: 1) Contact Engineering Design and request a quote. 2) International shipments will include an additional charge to cover customs paperwork. 3) Payment is by credit card via PayPal only. 4) New key will be sent via USPS or other secure means. 5) Standard turnaround is 2 weeks or sooner by arrangement.


Software requirements


SIGNAL and RTS support Windows 98, 2000, XP Pro, Vista and Windows 7. Built-in I/O support is currently available only for 32-bit versions of Windows Vista and 7. Contact Engineering Design re 64-bit support and support for other Windows versions.


Hardware requirements


SIGNAL and RTS run on desktop and notebook computers. The same program version is used for both platforms.

SIGNAL and RTS will run native on a Windows computer or a Macintosh with VirtualPC, Parallels or other PC emulator software.

Computer Requirements describes required and recommended Windows version, memory, disk, monitor, etc. for SIGNAL.

Data Translation DT2821-family ISA analog I/O boards provided with SIGNAL 3 are not supported by SIGNAL 4 and later because Data Translation discontinued support for Windows 98 and later.

Event Detector and Event Analyzer require no special hardware.

Experiment Maker requires National Instruments I/O boards to support all features. The 16-bit 1000 Hz / 2000 Hz desktop board shown above is highly recommended.
