Sampling rate increased to 125 MS/s for General Purpose Digitizers | Spectrum
Based on the latest 16-bit analog to digital (ADC) technology, the new M2p-596x series includes models that provide 1, 2, 4 or 8 input channels. Multi-channel models each have their own ADC and signal conditioning circuitry to allow fully synchronous acquisitions on all the inputs. Importantly, the high-resolution 16-bit ADCs deliver sixteen times more resolution than digitizers using older 12-bit technology and 256 times more resolution than what is available from digital scopes that commonly use 8-bit ADCs. The extra resolution translates directly into improved measurement capabilities and superior dynamic performance. It delivers a higher Signal-to-Noise Ratio (SNR), better Spurious Free Dynamic Range (SFDR) and less distortion than 12- or 14-bit products.
Oliver Rovini, CTO at Spectrum, said: “We’re delighted to expand our mid-range digitizer lineup with these new 125 MS/s, 16-bit models. They offer a great combination of speed, accuracy and performance, all at a very affordable price. We expect they will be very popular in a diverse number of applications such as Ultrasound, Laser, Lidar, Radar, Power, Automotive, Medical Science and even big Physics experiments.”
The complete product has been packed into a half-length PCIe card, yet it still offers a full set of digitizer features. Each channel has its own programmable input amplifier with ranges between ±200 mV and ±10 V, programmable input offset for unipolar measurements, programmable input termination of 50 Ω and 1 MΩ and an integrated calibration circuit. Models are available with up to 8 single-ended and up to 4 differential channels.
To match nearly every application requirement, the units come with a variety of signal triggering techniques, an impressive on-board memory of 1 GByte and a number of intelligent acquisition modes, such as multiple recording, gated sampling or ABA (the combination of fast and slow continuous acquisitions). At just 167 mm long, these multi-function digitizers fit into much smaller PC systems – making them perfect for compact OEM solutions.
