to enable or disable the frequency sweep mode of tracking generator.
·[Power 0.0 dBm]: Press
【
Measure
】 →[More 1 of 2]→[Generator]→[Power 0.0
dBm]; level range -40 dBm~0 dBm, default level 0 dBm, and 1 dB step; set the fixed or
sweep output power of the signal of tracking generator.
·[CW Freq 1.000 GHz]: Press
【
Measure
】
→[More 1 of 2]→[Generator]→[CW Freq
1.000 GHz]; frequency range 100 kHz~20 GHz, default frequency 1GHz, and 1, 2 or 5
step; valid when the tracking mode is Off. It is the output frequency of the independent
dot frequency generator.
·[Trans Meas]: Press
【

】
→[More 1 of 2]→[Generator]→[Trans Meas] to open
the submenu of [Trans Meas] . Refer to the description of “Transmission Measurement”
menu for details.
·[Power Offset 0.0 dB]: Press
【
Measure
】 →[More 1 of 2]→[Generator]→[Power
Offset 0.0 dB]; range-200 dB~200 dB, default 0 dB, and 1 dB step; valid when tracking
mode is On. Assign a certain offset to the output power of the tracking generator when
gains or losses occur between the generator output and the external device in order to
display the actual power value. This parameter only changes the power readout of the
tracking generator, rather than the actual output of the generator.
·[Frequency Offset 0.000Hz]: Press
【
Measure
】 →[More
1 of
2]→[Generator]→[Frequency Offset 0.000 Hz]; range -300 MHz~300 MHz, default 0
Hz and step invalid; valid when tracking mode is enabled; set the frequency deviation
of the output signal of the tracking generator from the current sweep frequency; the
frequency of the tracking generator must be within 100 kHz~20 GHz.

→[More 1 of 2]→[Generator]→[Trans
Meas]→[Normalize Off On]; range on or off; valid when the tracking mode is enabled
When normalization is enabled, the reference trace will be saved automatically after the
current sweep completes if no reference trace is saved before. In the saving process, a
corresponding message will be prompted on the screen. When normalization is enabled,
the corresponding value of the reference trace will be subtracted from the trace data
after every sweep.
·[Relative Ref 0.0 dB]:
【
Measure
】
→[More 1 of 2]→[Generator]→[Trans
Meas]→[Relative Ref 0.0 dB]; range -200 dB~200 dB, default 0 dB, and 1 dB step;
valid when both the tracking mode and the normalization are enabled. Adjust the
vertical position of the trace on the screen by adjusting the reference level when
normalization is enabled. Different from the reference level in the Amplitude/Scale
menu in the analysis mode, modification of this parameter will not affect the reference
level of the spectrum analyzer.
·[Ref Position 0]:
【
Measure
】
→[More 1 of 2]→[Generator]→[Trans Meas]→[Ref
Position 0]; range 0~10, default 5 and 1 step; valid when both the tracking mode and
the normalization are enabled. Adjust the vertical position of the normalization
reference level on the screen by adjusting the reference position when normalization is
enabled. When it is set to 0, the reference position is at the top; when it is set to 10, the
reference potions is at the bottom; when it is set to 5, the reference position is in the
middle.
