Abstract: An RF test set having a concurrent measurement architecture is provided. The RF test set is adapted for testing an RF communications device such as a cellular phone according to a set of RF tests. An RF source and an RF receiver are used to communicate with the cellular phone in order to perform the call processing operations to control the cellular phone while performing parametric measurements according to the RF tests. Concurrent measurements allow operation of concurrent measurement processes and call processing operations to take place in the RF test set in order to decrease the time required for each RF test and to increase measurement throughput of the RF test set.

Abstract: A method and system of efficiently switching between a first test application that tests a first format and a second test application that tests a second format. First, a fast test application switching module (FTASM) is loaded into a program memory. The FTASM has a format independent portion (FIP) and at least two format dependent portions (FDPs) that are specific to the particular format to be tested. The FIP is configured to be compatible with each of the format dependent portions so that any of the format dependent portions can utilize the FIP to perform testing tasks. When a first format test request is received, the FIP activates the virtual instruments associated with the first format. Then, when a second format test request is received, the FIP de-activates the virtual instruments associated with the first format and activates the virtual instruments associated with the second format.
