Cobham Wireless, formerly Aeroflex wireless business unit, has announced the introduction of a new measurement option that allows users to perform power measurements more quickly, directly reducing test times in power servo applications. Option 194 (Fast Power Measurement) on the PXI 3030 series RF digitizer results in a 57% reduction in servo loop time when applied to an LTE signal. This has given RFMD an overall 10% reduction in test time.
RFMD is a leading user of the Cobham Wireless PXI 3000 Series RF modular instruments. They have been integrating Cobham Wireless RF PXI sources and RF digitizers (302X and 303X respectively) into production test systems since 2005. RFMD uses these test systems to test amplifiers, switches, and numerous other RF components.
Having the on-board FPGA on the RF Digitizer (option 194) provides a much faster way of making measurements. Fast power measurement is extremely beneficial when testing cellular or WLAN power amplifiers as well as in many other applications. Measurements such as ACLR, EVM, and efficiency are made at a constant output power. Reaching the desired output power is an iterative process, which normally adds significantly to the measurement time. This gives customers like RFMD considerable potential savings in future capital expenditure.
More about Cobham Wireless Modular Instruments
The PXI 3000 Series RF modular instruments provide five generations of test capability covering most applications in RF design validation and wireless manufacturing test. Licensed options are available for LTE/LTE-A, GSM/UMTS/HSPA+, WLAN 802.11a/b/g/n/p/ac, GPS, Bluetooth, DECT, FM, and all generic standards.
The AXRF is a high-density, multi-site capable test platform. It adds RF test capability to existing digital IC testers with the same capabilities as the PXI 3000 Series.
