Sampler

Sampler is an 8-channel, 16-bit ADC EEM.

Sampler is an 8-channel, 16-bit ADC EEM with an update rate of up to 1.5 MSPS (all channels simultaneously, dual EEM mode). It has low-noise differential front end with a digitally programmable gain, providing full scale input ranges between +/-10mV and +/-10V.

General information

• Channel count: 8.
• Resolution: 16-bit.
• Sample rate: up to 1.5 MHz.
• Sustained aggregate data rate in single-EEM mode (8 channel readout): ~700 kHz.
• Sustained per-channel data rate in dual-EEM mode (SU-Servo): ~1 MHz.
• Note that the bandwidth specifications are for the hardware only; ARTIQ kernel and RTIO overhead often make the effective sample rate lower.
• Bandwidth: 200kHz -6dB bandwidth for G = {1, 10, 100}, 90kHz for G=1000.
• Input ranges: +/-10V (G=1), +/-1V (G=10), +/-100mV (G=100), +/-10mV (G=1000).
• ADC:    LTC2320-16.
• PGIA:   AD8253.
• EEM connectors: power and digital communication supplied by one or two EEM connectors.
• A 4HP version with MCX connectors is also available on request.

This module can be used for building control and measurement systems for optical and quantum physics experiments and quantum technologies development. In particular, the Sinara ecosystem is tailored to the needs of working with trapped ions and cold atoms. Compatible with ARTIQ software.
