Cobham Wireless PXI 3030 series RF digitiser

Cobham Wireless (formerly Aeroflex wireless business unit) has introduced a measurement option that enables 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 digitiser results in a 57% reduction in servo loop time when applied to an LTE signal.

Fast power measurement is 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. The Fast Power Measurement technique gives users a significant improvement in test time and considerable potential savings in future capital expenditure.

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.
