Overview
Overview
Immagine del prodotto

4-channel simultaneous sampling at 24-bit, 100 kHz for best-in-class noise performances in the evaluation of the beam position.

The CAEN ELS TetrAMM - e.g. "Tetra AMMeter" - is a 4-channel picoammeter device dedicated to accurate and fast low current measurements.

The presence of a fast Gigabit Ethernet Interface and an SFP (Small Form-factor Pluggable) link allow for very high-throughput data acquisition. Each channel is sampled independently and simultaneously at a maximum frequency of 100 kHz with a 24-bit resolution.

The integrated High Voltage source, with factory-configurable output rating and polarity, can be used to bias the connected detecting system. Standard voltage output is 500V or -500V (but can be customized up to 4 kV).

Integrated High-Voltage module for detector biasing. CAEN High-Voltage technology is integrated into this device.

The High Voltage integrated module is equipped with output voltage and current readbacks, as well as with protection features against over-current, thus protecting the detecting system from excessive power drawing.

On-board processing of data allows to obtain measurements on a user-defined sampling period, with minimum time steps of 10 µs.

Input trigger/gate signals are present on coaxial connectors and are configurable, thus allowing to synchronize the TetrAMM acquisition of the device to an external event.

Small mechanical dimensions are kept as in the previous AH401D and AH501D series in order to install the device as close as possible to the current sensor/detector and to minimize possible environmental noise pick-up. The TetrAMM device is the perfect replacement/upgrade for the AH501D bipolar picoammeter.

TetrAMM Oscilloscope software is included in order to have a ready-to-go measuring setup.

The CAEN ELS Oscilloscope software series allows customers to obtain instant and accurate results after connecting the TetrAMM device directly to the detector.
Different configurations for detector geometry, measuring range, sampling rate and other parameters can be configured directly via this free software.
