产品信息： The E8254A PSG microwave signal generator was discontinued0n November 1, 2002. Agilent will continue to support this product for the five years following its discontinuance date. The recommended replacement products are the PSG high-performance signal generators.
　　 The Agilent Performance Signal Generator series offers accurate characterization of products and eliminates the need of an external amplifier for testing high power devices. The PSG series provides 14 dBm at 40 GHz (option 1EA), reducing overall equipment and test costs. The superior level accuracy of the PSG series (+/- 0.7 dB) reduces test uncertainties and improves production throughput. Standard products have phase noise performance of -85 dBc/Hz at 1 kHz offset and -110 dBc/Hz at 20 kHz offset and a 10 GHz carrier. The PSG provides improved performance with option UNJ of -98 dBc/Hz at 1 kHz offset and -110 dBc/Hz at 10 kHz offset and a 10 GHz carrier. Because the new PSG series guarantees accurate evaluation of devices, errors can be pinpointed early0n in the design process thus resulting in a reduced development time.
