Digital Cable
The Keysight 34398A is an RS-232 cable, 9 pin (f) to 9 pin (f). Standard RS-232 cables are easy to find, but making them work is a different story. The Keysight 34398A has been verified for compatibility with Keysight's bench instruments to take the mystery out of RS-232 pinouts. The Keysight 34398A includes a 9-pin (f) to 9-pin (f) RS-232 cable and a 9-pin (m) to 25-pin (f) adapter.
