PXI Source Measure Unit
PXI Source Measure Units (SMUs) combine high-precision source and measure capability with features designed to reduce test time and increase flexibility. These features include high channel density for building parallel SMU test systems, deterministic hardware sequencing for minimizing software overhead, and high-speed update and sample rates for quickly changing setpoints and acquiring data. Additionally, the flexible sampling rate and streaming capability of PXI SMUs allows you to use the instrument as a digitizer to capture transient behavior, and the digital control loop gives you the ability to adjust the transient response of the instrument. The ability to change the transient behavior of the SMU, called SourceAdapt, reduces SMU settling time and minimizes overshoot and oscillations, even with highly capacitive loads.

Structure-Borne Sound Probe
T10
The T10 structure-borne sound probe can be used to monitor the condition of machines, systems and processes, provided that they generate detectable structure-borne sound in the ultrasonic range. Changes in the sound signals indicate a change in the condition and/or process of the plant. The detection of these changes forms the basis for condition monitoring in preventive maintenance. The T10 structure-borne sound probe is used when the installation space is very limited or the test specimen must not be loaded with a large sensor mass. The T10 structure-borne sound probe is also suitable for use on non-magnetic surfaces.

Sound Level Meters
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.
