I am utilizing the Keysight 4395A / 4396B combination analyzer in spectrum analyzer mode with the noise format. The units are set to V (volts) and the marker indication is 'nV / Hz'. Are the indicated units in error for this mode?

Due to 4395A / 4396B display limitations, the screen annotations are unable to correctly indicate the desired units of 'nV / √Hz'.

The limitations are documented within the related manuals as follows:

4395A:

Refer to the Keysight 4395A Network/Spectrum/Impedance Analyzer Operation Manual , 'Measuring the Noise Level', page 8-36 and the following excerpt:

4396B:
