measurement function is "On", displayed measurement
result is relative value relative to "normalization", unit:
"dB". When network measurement function is "Off",
displayed measurement result is spectrum measurement
result, unit: "dBm".
3.3.8.5 [Network measurement On Off]
Enable or disable tracking source network measurement
function.
3.3.8.6 [Output power]
Used to set output power of tracking source
3.3.8.7 [Reference level]
This soft menu is used by users of network measurement
of tracking source to adjust display position of measurement
result.
3.3.8.8 [Normalization]
This soft menu is used by users of network measurement
of tracking source to conduct calibration on the spot. After
connecting instrument RF output with RF input, press
"Normalization" soft menu, and a straight line is displayed
in 0dB scale on the display.
3.3.8.9 [Frequency discrimination test ]

Enable or disable frequency discrimination test function.
3.3.8.11 [Calibration]
It is used to calibrate test system of frequency discrimination
property. After calibration, system will generate calibration
file, such calibration file matches with frequency
discriminator at this moment.
3.3.8.12 [Amplitude
]
Under [Amplitud
] menu, firstly get to know requirements
of tested frequency discrimination network for amplitude
of input signal, and adjust instrument's output gain, so as
to make amplitude of instrument's output signal adapt to
tested frequency discrimination network, tested frequency
