TG Lvl Offset

Assign 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.

Key Points:

 This parameter only changes the readout of the TG output power, rather than

the actual value of it.

 The offset could be either a positive (gain in the external output) or a negative

(loss in the external output).

 You can use the numeric keys, knob or direction keys to modify this parameter.

For more details, please refer to “Parameter Setting”.

Power Sweep (Only for DSA815)

Enable or disable the power sweep function.

When enabled, the output power of the TG varies with the sweep rate of the

analyzer within the specified sweep frequency range (from start to stop frequency)

and increases gradually from the specified TG power (see “TG Level”) within the

specified power range (see “Power Range”). When disabled, the TG output is

fixed at the specified power (see “TG Level”).

Note: This function in not available in zero span mode.
