TTi distributes Gage's Razor digitiser cards

The recently released Razor family of high-speed, high-performance digitiser cards from Gage Applied is now available in the UK via TTi Instrument Distribution.

The multi-channel 16-bit digitisers feature up to four channels, 100MS/s or 200MS/s of maximum sampling per channel, up to 2GS of onboard memory and 65MHz or 125MHz bandwidths.

With its 16-bit nominal resolution, the Razor provides high signal fidelity with an effective number of bits (ENOB) of 12.

The ENOB is the universally accepted measure of a digitiser's combined noise and distortion performance.

The Razor also 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 signal averaging or filtering.

By contrast, there is no way of removing signal distortion, so the ultra-low distortion introduced by the Razor is said to provide a huge benefit.

In addition, ENOB performance is optimised on the 100MS/s and 200MS/s Razor models through the use of separate ADC chips on each model.

The Razor includes a high-voltage input of +/-50V, making it suitable for interacting with the 42V batteries soon to be introduced by emerging technologies in the military, aerospace and automotive industries.

It also provides an automatic high-voltage trip feature that protects the card against damage for voltages of up to +/-75V on most input ranges.

The Gage automatic calibration mechanism provides 0.5 per cent DC accuracy on all Razor input ranges.

True master/slave multi-card synchronisation allows up to eight cards to be simultaneously sampled in a single chassis.

A master/slave Razor system automatically performs an onboard timing calibration that ensures simultaneous sampling on all channels within 200ps.
