The Wiltron 560A is a GPIB-compatible scalar network analyzer for amplitude measurements of microwave components and systems. This three-channel instrument simultaneously measures transmission loss/gain, return loss, absolute power, and SWR across a broad frequency range determined by your choice of SWR Autotester and detector. Two independent measurement channels (A and B) plus a reference channel deliver dual simultaneous measurement display, making it ideal for rapid characterization of RF devices including filters, amplifiers, and passive networks.
Technical Specifications
