Load Testing vs. Stress Testing
-
A load test is a planned test to perform a specified number of requests to a system in order to test the functionality of the system under specific levels of simultaneous requests. A load test ensures that a web system is capable of handling an expected volume of traffic, and therefore is sometimes referred to as volume testing. The goal of a load test is to prove that a system can handle the expected volume with minimal to acceptable performance degradation. The threshold of acceptable performance degradation must be defined by the testers as some value considered acceptable to the end user so that users will not bounce from the site.

Spectrum Analysis, Up To 26.5 GHz
S930902B
-
The S930902B spectrum analysis adds high-performance microwave spectrum analysis to the PNA family up to 26.5 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Simultaneous spectrum measurements can be done using up to five test and reference receivers. This multi-channel SA can be used with the internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The SA application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy.

Room Temperature Sample Holders
12962A
-
The 12962A sample holder is designed to allow accurate impedance tests of solid materials to be performed at room temperature. The sample holder consists of two parallel electrodes, one of which is fixed in position and the other which can be moved into contact with the sample by adjustment of a micrometer. The sample holder makes use of guard ring and reference techniques in order to improve accuracy by reducing “fringing” effects at the edge of the sample. The standard electrode provided is 20mm diameter.

8-Channel, 10 MHz Precision ReferenceWith Sine and Logic Outputs
ITS-6200
-
The ITS-6200 is a versatile 10 MHz laboratory frequency reference useful for synchronizing test instruments to a common standard. Eight outputs are provided, each which can be configured independently as sinewave or logic level square-wave signals. Additionally, CMOS logic levels can be set for 5V, 3.3V, or 2.5V logic family compatibility. A 10 MHz reference input is provided to phase lock the ITS-6200 to an external reference, such as a GPS or Rubidium standard, or cascade multiple ITS-6200 units for additional outputs. The low phase noise and high stability OCXO within the ITS-6200 is suitable for the most demanding applications, whether free-running or phase locked. The compact size and low power consumption makes the instrument highly portable and suitable for AC-powered operation in the lab or battery operation in mobile or field applications.

The short-circuit test system refers to what kind of short-circuit test is carried out by which equipment, and how long is the test time. But I have one thing to tell you, the short circuit test is a kind of destructive test, mainly to test the working condition of the used equipment in a crisis situation, or to test how strong the anti-destructive ability of the used equipment is. Just like a lot of equipment in the military must undergo a short-circuit test, some for 3 minutes or longer, in order to resist breaking calls against the enemy during wartime.
