The Multiprotocol Network Tester is a freeware, open source tool which enables you to measure quality of your IP network. It can also be used to generate UDP flood or to simulate UDP DoS attack. SIP call is usually established using a SIP session with a bidirectional RTP stream. SIP and RTP protocols are based on UDP transport protocol. UDP uses a simple transmission model without implicit reliability, ordering and data integrity. Each single UDP packet is transferred independently. The quality of a SIP call depends on delays and loss of IP packets in a network. Long delays lead to large RTP jitter and bad sound quality of a SIP call.

SHF Communication Technologies AG
SHF’s microwave components are broadband devices suitable up to 110 GHz. Our SHF BIAS TEES are well known but perhaps a slight variation does suit your application even better. DIPLEXERS are bias tees with a certain bandwidth in the low frequency path to combine or separate high frequency and low frequency signals into or out of a single line. DC-FEEDERS are bias tees without the capacitor. Therefore, it provides slightly lower insertion loss in case it is connected to an AC-coupled device which already has a capacitor on its input. Based on our air line construction, these passive components provide resonance-free transmission over the entire operating range.

Vishay Intertechnology, Inc.
A passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.

D.Marchiori s.r.l.
D.Marchiori (DMA) manufacture double or triple tachometer testers. They use precision controlled DC motors with coaxial optical encoders controlled by a dedicated microprocessor. A quartz timing circuit provides maximum accuracy and control stability. Speed values (% or RPM), rotation direction, transmission ratio and 100% RPM values can be selected separately for each motor. The test set can apply star or triangle resistive load and read the output voltage for generator checks; by entering RPM and test voltage limit values the full generator check can be automatically carried out. The internal printer provides copy of the test results. Safety limits to protect UUT can be set separately for each motor.
