Displaying Phase Values without Wrapping at ±180°
The Agilent 4294A provides a feature that allows you to display phase values without
wrapping them at +180° or -180°. This feature, called “expanded phase,” is useful when
measured phase values are in a continuous increase or decrease and some of them exceed
+180° or -180°. To set up the expanded phase feature, follow these steps:
Step 1. Activate the trace for which you want to use the expanded phase feature.
NOTE To expand the phase, your parameter must be either |Z|-q / |Y|-q or COMPLEX Z-Y. You
should activate Trace B in the former case, and the trace whose axis format is polar in the
latter case.
Step 2. Press the
[Format] key to display the Format menu.
Step 3. Press the EXP PHASE on OFF (or EXP PHASE ON off) key to turn on or off the expanded
phase feature (pressing the key toggles your selection).
To activate: Press:
Trace A
[A]
Trace B [B]
Softkey Labels Description
EXP PHASE ON off Indicates that the expanded phase feature is
enabled.
EXPPHASEon OFF Indicates that the expanded phase feature is
disabled.
