Power Meters The 478A Option H83 comes with calibration data for 1, 3, 10, 30 ,50, 100, 300, and 1000 MHz from a Standards Calibration Lab, which is traceable to NIST. All other specifications in the 478A Operating and Service Manual, Table 1 apply except where 431 use is referenced in the standard manual. -
Page 12: Mount Calibration
Mount Calibration Data The calibration factors are essentially the same (within 1%) as the Effective Efficiency for the 478A Option H83 over the 1 MHz to 1000 MHz frequency range. Both vary less than the measurement uncertainties that apply to any calibration data, and typically remain between 98% and 100%. -
Page 13: Operation
DC signals to and from the mount (432 type) are suitable for use with the 478A Option H83. Thus, paragraphs 16, 26 through 30, 43, 44, 50, 52, and 53 in the Operating Note, as well as Figures 4 and 5 do not apply. -
