Scale Setting

Rectangular Scale

For rectangular format you can set the following parameters (See Figure 35):

• Scale division;
• Reference level value;
• Reference level position;
• Number of scale divisions.

  Rectangular Scale Setting

You can set the scale for each trace of a channel. Before you set the scale, first activate the trace.

To set the scale of a trace, use the Scale softkeys.

Circular Scale

For polar and Smith chart formats, you can set the outer circle value (See Figure 36).

Circular Scale Setting

To set the scale of the circular graphs, use the softkeys.

Automatic Scaling

The automatic scaling function automatically adjusts the trace scale so that the trace of the measured value fits into the graph entirely.

In rectangular format, two parameters are adjustable: scale division and reference level position. In circular format, the outer circle value is adjusted.

To execute the automatic scaling, use the AutoScale softkeys.

Reference Level Automatic Selection

This function automatically selects the reference level in rectangular coordinates. After the function, the trace of the measured value shifts vertically so that the reference level crosses the graph in the middle. The scale division is unaffected.

To execute automatic selection of the reference level, use the corresponding softkeys.

Electrical Delay Setting

The electrical delay function allows the user to define a compensation value for the electrical delay of a device. This value is useful during measurements of phase deviations from linear, for example. The electrical delay is set in seconds.

The electrical delay is set for each trace independently. Before you set the electrical delay, first activate the trace, then use the softkeys to change the electrical delay setting.

Phase Offset Setting

The phase offset function allows the user to define the constant phase offset of a trace. The value of the phase offset is set in degrees for each trace independently. Before you set the phase offset, first activate the trace.
