Multichannel digitisers

27 November 2025 Test & Measurement

Spectrum Instrumentation has released new flagship digitisers with 12-bit resolution and a maximum of 6 channels at 10 GS/s or 12 channels at 5 GS/s acquisition speed. The new DN6.33x digitisers belong to the company’s Netbox series, an easy-to-use instrument line that requires only an Ethernet cable to be controlled from any PC, laptop, or network.

A comprehensive software package combined with hardware features make them ideal for automated testing applications, capturing signals on multiple, perfectly synchronised inputs. With 15 new variants, Spectrum now offers a total of 94 different digitiser Netboxes, ranging from 5 MS/s to an ultrafast 10 GS/s sampling speed.

Each channel of the new DN6.33x digitisers features a 12-bit ADC with sampling rates of 3,2 GS/s, 6,4 GS/s, or 10 GS/s, and related analogue bandwidths of 1, 2, or 3 GHz. Models are available with 4, 6, 8, 10, or 12 channels, providing flexibility to users. The smaller DN2.33x series is also available if only 1 or 2 channels are required.

The units feature four independent programmable input ranges (±200 mV to ±2,5 V) per channel with programmable offset, on-board calibration, and precise timing alignment. The standard memory allows 200 ms capture duration at full speed, expandable to 800 ms.

Flexible acquisition modes like transient, multiple, and optional block averaging, combine with advanced trigger capabilities to allow the precise capture of rare or complex events. Each trigger has its own timestamp, making it possible to time between acquisitions that may be separated by hours, or just fractions of a microsecond.

These digitisers are ideal for use in communications or radar, aerospace, scientific research, photo-voltaic analysis, and semiconductor analysis.
