To avoid confusion, please note (conform) to the following *standard*
notation in emails:
mHz or mhz = *MILLI*hertz = 1E-3 Hz (subsonic)
MHz or Mhz = *MEGA*hertz = 1E+6 Hz
GHz or Ghz = *GIGA*hertz = 1E+9 Hz
This notation is standard throughout the communications, RF and microwave,
EMC/RFI, and RCS..... disciplines. Please adhere to this notation to avoid
confusion.
None of the NANOVNA's cover into the millihertz (subsonic / sudio) range!!!
