Agilent Technologies introduced what it believes is the world’s fastest vector signal generator in a PXI form factor.
The M9381A is a 1 MHz to 3 GHz or 6 GHz VSG that combines fast switching, high output power, linearity and level accuracy, elevated adjacent channel power ratio performance (for output levels up to +10 dBm or more) and wide modulation bandwidth (up to 160 MHz) for testing RF devices.
Agilent designed the M9381A for applications such as testing and validating the design of wireless power amplifiers and transceivers, public safety and military radios, and cellular base stations (primarily picocell and femtocell).
Agilent’s baseband-tuning technology innovation enables frequency and amplitude switching speed as fast as 10 μs in list mode and 250 μs from its programming interface.
The versatile list mode helps increase speed and provides flexibility by allowing engineers to change 80 parameters, including frequency, power and modulation in as many as 3201 list mode points. This enables engineers to meet a wide variety of test requirements while improving test throughput.
Engineers can use the instrument to test wideband power amplifiers, front-end modules, transceivers and more, at standard 40 MHz RF bandwidth or options of 100 MHz or 160 MHz bandwidth with real-time corrections and ±0,1, ±0,2 and ±0,3 dB flatness, respectively.
The M9381A can be used at power levels up to +10 dBm or more (depending on the standard) with little degradation to adjacent channel power ratio performance. This enables engineers to directly operate at the required power levels without additional amplification to compensate for test system losses.
The VSG delivers ACPR of up to -70 dBc (W-CDMA test model 1, 64 DPCH). The output power up to +19 dBm can be controlled precisely with accuracy of ±0,4 dB.
The M9381A simulates complex real-world communications signals through Agilent’s Signal Studio software, which is a flexible suite of signal-creation tools that offers performance-optimised reference signals validated by Agilent to support standards such as LTE and 802.11ac.
