Focus Microwaves - Noise Modules
of the cold-source noise figure measurement technique. This specific technique requires a noise source to determine the kBG (gain-bandwidth constant) of the system and a passive mechanical tuner is used to characterize the noise receiver across both the impedance and frequency space. This step is imperative to obtain fully vector-source-corrected measurements.
A RF down conversion stage might be required if the frequency of noise measured exceeds the receiver’s bandwidth. Focus offers noise modules which support down conversion for optimal speed and performance.

EMC test equipment to evaluate the resistibility of electronic devices and components when energy charged on a human body or object is discharged to the electronic devices and components. NoiseKen brand ESD simulator is available to see malfunctions or function declines of electronic equipment for appropriate evaluations compliant with IEC 61000-4-2 Ed.2 Test Standard, ISO 10605 Ed.2 Test Standard & ISO 10605 Ed.3 Test Standard.
The ESS-S3011A features a function which enables the user to pre-program test settings to minimize setup errors as well as having the unit be incorporated into a remote or autonomous testing setup. Another feature that sets apart NoiseKen ESD guns to that of competitors is the discharging gun separation design which helps achieve the lightweight.
For conventional ESD guns, that have generators that are inseparable from the gun, you may experience having to replace the whole unit even only when certain parts of the unit are broken. However, with the NoiseKen’s separation design, replacement parts can be minimized to lower the running cost.
