VDI Millimeter-Wave Frequency Extension Modules for PXA, MXA, EXA Signal Analyzers
These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.

Counter Electrodes
For a system using a three-electrode potentiostat, we measured current when a potential is applied between the working electrode and the reference electrode. Passage of current through an electrical circuit requires electron transfer reaction between the working electrode and the counter electrode.The main function of the counter electrode is to provide the location of the second electron transfer reaction. Important parameter of the counter electrode is the surface area. It is required (area) large enough to support the current generated for the working electrode. For example, the surface area of the platinum electrode of 5 cm is sufficient to use as an electrode, such as steady-state cyclic voltammetry experiments. However, for generating a high current measurements such as bulk electrolysis, the counter electrode of a larger area is required, as Catalog No.012961 which the length of platinum is 23 cm. This electrode is used for measurement, such as rotating ring disk.
