PC? The analyzer’s source could not be set to the desired level, following a power meter calibration. (For power meter calibration procedures, refer to Chapter 5, “Optimizing Measurement Results.” For power meter calibration theory, refer to Chapter 6, “Application and Operation Concepts “)

F? Source power is unleveled at start or stop of sweep. (Refer to the HP 8753E Network An.uZgm Semrice Guide for troubleshooting.)

Fast sweep indicator. This symbol is displayed in the status notation block when sweep time is less than 1.0 second. When sweep time is greater than 1.0 second, this symbol moves along the displayed trace.

Source parameters changed: measured data in doubt until a complete fresh sweep has been taken.

4.Active Entry Area. This displays the active function and its current value.

5.Message Area. This displays prompts or error messages.

6.Title. This is a descriptive alphanumeric string title that you define and enter through an attached keyboard or as described in Chapter 4, “Printing, Plotting, and Saving Measurement Results. n

7.Active Channel. This is the label for the active channel, selected with the @Gily(Chan 3) and w(Chan 4) keys. If multiple channels are overlaid, the labels will appear in this area. The active channel is denoted by a rectangle around the channel number.

For multiple-graticule displays, the channel information labels will be in the same relative position for each graticule.

Note

The label of the active channel is enclosed in a rectangle to differentiate it

 

from inactive channels.
