M2p.59xx digitizer series now available with four different speeds
Spectrum Instrumentation has announced the addition of five new models to its general purpose M2p.59xx series of PCIe 16-bit digitizer cards. Now, this digitizer family offers 18 product variations with the sampling rates of 20 MS/s, 40MS/s, 80 MS/s and finally 125 MS/s. The new cards are ideal for use in applications where signals in the DC to 50 MHz frequency range need to be acquired and analyzed with speed and accuracy.

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.
