TG
Press [TG] key to enter tracking source panel menu.
Tracking source（on/off）: Turn on/off tracking source.
After the tracking source is turned on, [TG] key indicator on the front panel will light up, and the [Gen
Output 50ω] connector on the front panel will output a signal with the same frequency as the current
sweep signal. The power of the signal can be set through the menu.
Amplitude: Set the output power of the tracking source signal. User can change the amplitude value by
using the number key, rotary knob, direction key or touch the panel menu.
Deviation: When there is a gain or loss between the output of the tracking source and an external
device, this parameter is used to set the output power offset of the tracing source to display the actual
power value of the system. User can change the offset by using the number key, rotary knob, direction
key or touch the panel menu.
Normalization: turn on/off normalization. If the operation of saving the reference trace has not
performed before turning on normalization, the spectrum will automatically save the reference trace
when the current sweep frequency finished. During the saving of reference trace, prompt message will
display on the interface. When the normalization is enabled, the corresponding value of the reference
trace is subtracted from the data after each sweep.
Reference level value: When the normalization is enabled, adjusting reference level value to change
the vertical position of trace on the screen. The changing of this parameter will not affect the reference
level value of the spectrum. User can change the reference level value by using numeric key, rotary knob,
direction key or touch panel.
Reference trace: turn on/off the reference trace display.
Note
This parameter does not change the actual output power of the tracking source, but only changes the
power reading of the tracking source. The offset value can be positive or negative. A positive value
corresponds to an external output gain, and a negative value corresponds to an external output loss.
Single
[Single] key which is the quick key of sweep mode. See Chapter 4 "Sweep" for more details.
Touch/Lock
[Touch/Lock] key, if indicator turns red, it presents the touch function is locked. If the indicator off, it
presents the touch function is enabled.
Meas/Setup
Press [Meas/Setup] key to open the parameter setting panel menu corresponding to the measurement
selected by the current [Meas] function key. It includes the following setting.
