Figure 56 Example, Ampt & Trace Menu

Autoscale

Resizes the graph to fit the whole trace on the screen. This function changes the

reference and scale of a trace.

Reference

Sets the y-axis value at the top of the graph.

Scale

Sets the dB value of each partition of the graph on a scale from 1 to 15. The

graph is partitioned into 10 divisions, giving a set number of dB per division.

Note: This soft key is not displayed if the Units of measure is in Volt

or Watt. See “Units” on page 71.

Attenuation

Controls the built-in attenuator on the signal input. This reduces the amplitude of a

high-powered signal. The attenuation can be set to Auto, or at levels of 0, 10, 20,

and 30 dB. The reported value of the signal is automatically corrected for the

selected attenuation.

Note: When the Reference (see “Reference”) is set to a higher set-

ting, Attenuation will automatically set itself above this setting.

Example - When the Reference is set to 25 dBm, Attenuation

automatically sets itself to 30 dB and cannot be lowered.
