Keysight 478A Sensors: Additional Information
The Voltage Reflection Coefficients (VRC) of the Keysight 478A sensor must be
known before attempting to perform the Output Standing Wave Ratio (SWR) Test.
The VRC values required for this test are as follows:
– Frequency 50 MHz, with the mount resistance of the Keysight 432A set to 200
(recorded as ).
– Frequency 50 MHz, with the mount resistance of the Keysight 432A set to 100
(recorded as ).
For reference only, typical values of these VRC values are as follows:
