Agilent debuts EXA economy signal analyzer
-- Test & Measurement World, 10/1/2007
Agilent Technologies’ EXA signal analyzer provides flexible, scalable signal analysis to budget-conscious engineers. At a lower performance point than Agilent’s MXA signal analyzer, the EXA includes a set of standard one-button measurements for characterizing signal quality. It measures adjacent-channel power ratio (ACPR), channel power, occupied bandwidth, power complementary cumulative distribution function (CCDF), burst power, and spurious emissions. It also includes a spectrum-emissions mask function.
Optional measurement application software provides preconfigured test routines for GSM/EDGE, 802.16e Mobile WiMAX, W-CDMA, HSDPA/HSUPA, and phase-noise applications. Running the Agilent 89600 VSA software application in the EXA enables signal demodulation analysis and troubleshooting of more than 50 demodulation formats, including 2G, 3G, 3.5G, WiMAX, WLAN, and Private Mobile Radio.
The EXA returns a marker peak search result in less than 5 ms, local updates in less than 10 ms, and a remote sweep and transfer (via GPIB) in less than 12 ms. Measurement mode switching speeds are typically less than 75 ms.
The EXA signal analyzer supports multiple frequency ranges from 9 kHz to 3.6, 7.0, 13.6, and 26.5 GHz, an internal fully calibrated pre-amplifier option up to 3.6 GHz, and standard analysis bandwidths of 10 MHz. This fully scalable functionality is complemented by EXA’s +13-dBm third-order intercept, –146-dBm/Hz displayed average noise level (without pre-amp), and 66-dB W-CDMA ACLR dynamic range, as well a 0.4-dB total absolute amplitude accuracy, which is made possible by the all-digital, 14-bit ADC IF section.
Base prices: from $16,900 for a 3.6-GHz model to $35,900 for a 26.5-GHz model. Option prices start at $1000. Agilent Technologies, www.agilent.com.
