For the very latest specifications visit www.aeroflex.com This same configuration is suitable for amplifier or mixer intermod testing in which case two (or three) 3025s can be connected to ports A, B and C providing a single combined RF input to the device under test from the (Ó) port. Combining two 3065 modules permits a single set of RF signal generation and analysis instruments to switch between multiple devices. Depending how they are configured, testing is ether performed sequentially or in parallel thus saving time and money. Figure 4 – Dual RF transceiver test with two 3065 modules For even greater throughput, up to three test devices can be connected in parallel and share a single RF test resource. This is ideal for communication devices using TDMA (Time Division Multiple Access). This not only saves on test time but also on device handling time as well. Figure 5 - Testing three devices Today’s modern mobile phones commonly support additional noncellular functions such as GPS, FM radio and DVB. In which case a second RF source is often required. The second RF source is used concurrently so that cellular mode testing and non cellular mode testing can be performed in parallel. The device under test has independent RF connection points which may now utilize the additional low power D port of the 3065.
