Model101 Picoammeter  fast, accurate measurements in a low cost instrument

Model 101 is a high quality picoammeter that provides quiet, stable readings and fast response.

Technical Features
AutoZero Function. The unit is equipped with an AutoZero function that ensures that the input burden voltage remains as close to zero as possible, thus compensating for time and temperature induced drifts.
Solid State Switching. Solid state range switching eliminates the uncertainties associated with electromechanical relays.
Isolation. The Model 101 can float up to ±300 V from Earth ground permitting accurate high-side current measurements.
Data Interface. The unit is equipped with an USB interface that is easier to use, more cost effective than GPIB or RS-232 and eliminates non-native operating system support, expensive GPIB cards and expensive cables.
Bias Supply. The quiet programmable voltage bias supplies ensure stable current measurements. These supplies have fine resolution to allow precise adjustment. The voltages can be monitored by the measurement system to verify the actual voltages and the included interlock connector can be used to disable the supplies when the device is under test is being installed in a fixture. The high voltage bias supply can be used for biasing silicon photodiodes, biasing avalanche photo-diodes, characterizing the low current regions of semiconductors, and high-megohm resistance measurements.
Data Display. The Model 101 Picoammeter leverages the user’s computer for data display since typically users use their PC for storage, analysis, or reporting, rendering an additional display redundant.
Soft Front Panel. The intuitive user interface provides control, display, and data logging functions.
User Created Interface. The Model 101 Picoammeter provides powerful APIs for data acquisition and control. Support for user-written software in Visual Studio® or LabVIEW™.
Digital I/O. The digital I/O interface, can be configured to drive selected pins based on measurement levels, which is ideal for alarms and part binning. Users can control the digital I/Ovia scripted commands or buttons within the user interface. The digital I/O lines are compatible with traditional TTL signal levels and can detect up to +24 V logic levels or sink 24 V loads at up to 200 mA.
