E8251A PSG-A Series Performance Signal Generator, 20 GHz
Description
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 20 dBm at 20 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 early on in the design process thus resulting in a reduced development time.
