The Advantest R3671 is one of the new measuring instruments for this new era of test and measurement requirements. The R3671 is a high performance signal analyzer. Employing its unique RF technology, the it achieves an Average Display Noise Level of -158dBm *1), a Third Order Intercept Point (TOI) specification of +26dBm *2), and a signal purity of -122dBc/Hz *3) to enable measurements over a wide dynamic range. The R3671 also has a unique noise correction function that enhances its dynamic range (-84dBc [typical]) for W-CDMA adjacent leakage power (ACLP) measurements. It supports a standard broadband modulation analysis function (bandwidth 25MHz). This functionality enables testing of next generation digital radio communication standards.
