GaGe Intros High Speed, Multi-Channel Digitizers
Single-slot multi-channel PCI digitizing card.
Lockport, IL — GaGe has introduced The Razor
family of high-speed, high-resolution, multi-channel digitizers. The Razor CompuScope 16XX family provides up to 4 channels in a single-slot PCI card with up to 200MS/s sampling per channel, and up to 4GB of on-board acquisition memory.
The company also recently introduced a 16-bit version of the Octopus
digitizers that provide up to 8 channels in a single PCI card and sampling speeds up to 25MS/s,
In tandem with its 16-bit nominal resolution, the Razor provides extremely high signal fidelity with an Effective Number of Bits (ENOB) of 12. The ENOB is the universally accepted measure of a digitizer's combined noise and distortion performance. The instrument provides an ultra-low Total Harmonic Distortion (THD) of less than -80dB. In many applications, low-distortion is far more important than low-noise since noise may often be reduced through signal processing techniques, such as that provided by the company's eXpert
Signal Averaging or FIR Filtering FPGA technology. By contrast, there is virtually no practical way of removing signal distortion through signal processing, so that the ultra-low distortion that is characteristic of the Razor provides a huge benefit.
In addition, ENOB performance is optimized on the 100MS/s and 200MS/s Razor models through the use of separate ADC chips on each model. The Razor also includes a high voltage input of ±50V. This input voltage is suitable for interacting with the 42V batteries being introduced by the mil/aero and automotive industries. The ±50V input range is the highest input range available in a digitizer on the market today. Typically, such high input voltages are found in oscilloscopes, but not digitizers.
The Razor also provides an automatic high-voltage trip feature that protects the card against damage for voltages of up to ±75V on most input ranges. Gage's, now perfected automatic calibration mechanism, provides 1/2 percent DC accuracy on all Razor input ranges.
With true Master/Slave multi-card synchronization, the Razor enables up to 8 cards, or 32 channels, to be simultaneously sampled in a single chassis. The system automatically performs on-board timing calibration that ensures simultaneous sampling on all channels within 200 picoseconds.
Drivers are supplied for Microsoft Windows
Vista, XP and 2000, as well as a free Lite Edition of the company's powerful GageScope
PC Oscilloscope software. SDKs for LabVIEW, MATLAB, and C/C# are also available.
