2.2.7.1
TG
The tracking generator is a signal source with an adjustable frequency and amplitude. When the TG is
enabled, a signal with the same frequency of the current sweep signal will be output from the
[TG
SOURCE]
connector at the front panel. The power of the signal could be set through the menu. The TG
output frequency follows the analyzer sweep frequency. For example, if the sweep is set to scan from 1
MHz to 10 MHz, the TG output frequency will change from 1 MHz to 10 MHz in coordinated steps with
the sweep. In Zero Span mode, the TG frequency will match the center frequency of the analyzer.

2.2.7.3
TG Level Offset
Assigns a certain offset to the output power of the TG when gains or losses occur between the TG
output and external device in order to display the actual power value.
This parameter only changes the readout of the TG output power, rather than the actual value.
The offset could be either a positive (gain in the external output) or a negative (loss in the external
output).

Normalize
Normalization can eliminate errors in the TG Level. Before using this function, connect the
[TG
SOURCE]
output terminal of the TG with the
[RF INPUT]
input terminal of the analyzer.
The reference trace can be stored by pressing the
“Store Ref” button after the current sweep finished.
Then the normalize function can be enabled. When normalization is enabled, the corresponding value
