Total Sulfur Analyzer
Model T108
-
Teledyne Advanced Pollution Instrumentation
The Model T108 Total Sulfur analyzer is designed to measure mixed sulfur impurities, collectively referred to as Total Sulfides, in air or carbon dioxide gas. Since there is no scrubber in the system, the instrument reading is the sum of the oxidized sulfur compounds and SO2.The Model T108 consists of a modified Model T100 SO2 analyzer with special software and a Model 501TS high temperature thermal oxidizer. Sulfur compounds are heated as they pass through the converter and oxidized into SO2. When analyzing CO2, which generally contains no oxygen, approximately 6% O2 is added to the sample before entering the converter. This dilution is corrected in the calibration procedure.

ACCUplace Dot Distortion Target
AP-DD Series
-
All machine vision lenses will show some type of distortion. Minimizing or correcting that distortion is crucial in most applications. The ACCUplace Dot Distortion target is designed to detect the presence of both barrel/pincushion distortion as well as alignment distortion that causes the keystone effect. The precise amount of distortion is determined from an array of precisely placed dots in a regular array. The results can be used to correct for any distortion that occurs within the optical system. The AP-DD is offered on three standard substrates; Chrome on Glass (CG) Opal (OP) and Photo Paper (RM).

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

Modulation Distortion Up To 50 GHz
S930705B
-
S930705B enables fast and accurate active-device modulation distortion characterization under modulated stimulus condition up to 50 GHz. The wide dynamic range and vector error correction of the PNA-X result in an extremely low residual EVM of the test setup, so you can get a complete picture of your device’s performance without test system interference. S930704B can measure EVM, NPR, ACPR, and can decompose nonlinear signals and linear signals with the spectral correlation between input and output spectrum without doing demodulation. Integration with the PNA-X SCCM provides quick modulation distortion measurements while making other VNA measurements.
