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:
