Description
High Precision Measurements with the TetrAMM Picoammeter
The TetrAMM Picoammeter is a powerful measurement instrument designed to capture extremely small currents with exceptional accuracy and speed. Built for modern research laboratories, beam diagnostics, and detector monitoring systems, it offers four independent measurement channels that operate simultaneously with a 24 bit resolution and sampling rates up to 100 kHz. This capability ensures precise signal acquisition even in demanding environments where noise performance and measurement stability are critical.
Each channel operates independently, allowing users to perform synchronized multi channel current measurements with consistent accuracy. The wide measurement range supports bipolar current readings from nanoampere levels up to microampere ranges, making the device suitable for a variety of scientific and industrial applications. Its high resolution electronics and optimized signal conditioning ensure reliable results even for extremely small signals.
Integrated Bias Voltage Source
A key advantage of the TetrAMM Picoammeter is its integrated bias voltage source. The system includes a low noise bias module that can supply detector bias voltages from a standard bipolar ±30 V configuration to higher voltage options such as 500 V, 2 kV, and up to 4 kV depending on the model. This integrated capability eliminates the need for external power supplies and simplifies detector setups in laboratory environments.
The bias source includes built in voltage and current monitoring, along with over current protection to safeguard sensitive detection systems. These protection features help maintain stable measurement conditions while preventing damage caused by excessive power draw.
Fast Data Acquisition
The TetrAMM Picoammeter integrates high speed data acquisition capabilities through Gigabit Ethernet connectivity and an SFP communication link. These interfaces enable high throughput data transfer, allowing real time monitoring and analysis of measurement signals. Onboard FPGA processing also allows users to define custom sampling intervals with time steps as short as 10 microseconds.
The device also includes configurable trigger functionality. Users can detect signal threshold crossings and generate trigger outputs in single or continuous modes. Adjustable polarity and trigger speed options allow precise event detection for applications such as beam monitoring, machine protection systems, and laboratory instrumentation synchronization.
Plug and Play Operation with the TetrAMM Picoammeter Software
To simplify operation, the TetrAMM Picoammeter includes dedicated oscilloscope software designed for rapid setup and visualization. After connecting the instrument to a detector, users can quickly configure parameters such as detector geometry, measurement range, and sampling rate directly through the software interface. This user friendly environment enables immediate measurement visualization and simplifies data analysis.
The software driven configuration and high speed connectivity make the device particularly effective for applications such as photon beam position monitoring, detector current analysis, and precision laboratory measurements where multiple channels must be monitored simultaneously.
