The Keysight (Agilent) 85131E is a 96.5 cm (38 in) flexible microwave test cable with a 3.5 mm female to PSC-3.5 mm female connector, engineered for high-frequency applications up to 26.5 GHz. It offers excellent return loss performance (≥16 dB) and low insertion loss defined by 0.35√f + 0.3 (test port) and 2.1 dB maximum (device end). The cable's flexible design ensures consistent performance in tight test setups.
With phase stability under 0.22 dB and phase shift of 0.16*f + 0.8° (f in GHz) under a 90° bend (4" to 3" radius), the 85131E is ideal for precision measurements where repeatability and low signal distortion are critical.
