85130G
Designed to protect the test set port with a special rugged female connector and a return loss of 23 dB or better
The Keysight 85130G test port adapter is designed to protect the test set port when it would be directly connected to the device under test. These adapters have a special rugged female connector designed for connecting to the network analyzer test port. This special connector will not mate with a standard male connector, but converts the rugged test set port to a connection that can be mated with the device under test. The set contains a NMD-2.4 mm (f) to NMD-2.4 mm (m) adapter and a NMD-2.4 mm (f) to PSC-2.4 mm (f) adapter. The frequency range for these adapters is dc to 50 GHz with a return loss of 23 dB or better.
85130F
Designed to protect the test set port with a special rugged female connector and a return loss of 26 dB or better
The Keysight 85130F test port adapter is designed to protect the test set port when it would be directly connected to the device under test. These adapters have a special rugged female connector designed for connecting to the network analyzer test port. This special connector will not mate with a standard male connector, but converts the rugged test set port to a connection that can be mated with the device under test. The set contains a 2.4 mm to PSC-3.5 mm male adapter and a 2.4 mm to PSC-3.5 mm female adapter. The frequency range for these adapters is dc to 26.5 GHz with a return loss of 26 dB or better.
85130D
