Figure 28 Example, Ampt & Trace Menu
Autoscale
Resizes the graph to fit the whole trace on the screen. This function
will change 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 42.
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
setting, Attenuation will automatically set itself above this setting.
Example - Reference is set to 25 dBm, Attenuation automati-
cally sets itself to 30 dB and cannot be lowered.
