Coax Patchcord
Connects measurement and signal generation devices. Model options include industry-standard coaxial connector types including BNC, SMA, SMB, and MCX. Long cables can act as antennae picking up extra noise that can affect measurements, so ensure you select only the length required for your test system. Also look at the impedance of your test system and consider buying a cable with the same impedance. Matched impedance can maximize the power transfer or minimize signal reflection from the load of your system.

Electromagnetic anechoic box/Shield box/Anechoic chamber
-
The necessity of a wireless system test has risen by the spread of recent wireless telecommunication equipment as shown in cellular phone, wireless LAN, RF-ID tag and ETC (Electronic Toll Collection system). It is necessary for a wireless test to be performed in anechoic environment in which an external noise is intercepted and a radio wave does not reflect internally. An anechoic chamber (room version of a shield box) is proper facilities but needs a wide space and a huge cost. Especially, the equipment under wireless system test on the production line can not radiate any signal radio wave outside before approval. The shield box satisfies these conditions.
