SMA M/F 6GHz Semi-Flexible cable RG402 - 10cmThe semi rigid nature of the cable allows for stable measurement independently of the position and helps on adding mechanical robustness when using RF Explorer Signal Generator with RF Explorer Spectrum Analyzer as Tracking Generator. You will typically need two of these cables to connect the Tracking Generator to a device (with two SMA male connectors) or use an equivalent Male to Male version for a device with different SMA gender connectors.
