These cables are precision 50 Ohms RF interconnect cables for the 8753 network analyzer to 85046A or 85047A S-parameter test sets. The cables use slotless N type connectors for low SWR and are cut to precise lengths for equal time delay (phase matching). Typical phase match error is less than 2 degrees at 6 GHz among a set of four cables. Each cable is swept to 6 GHz, but is usable to 18 GHz. These cables also can be used with the 35677A, 8503A, and 87511A 50 Ohms parameter test sets in place of the 8120-4387 RF cables. Sold in matched sets of four and standard length of 7.5 inches (19.05cm).
