8003 Precision Scalar Analyzer
2-10 Manual 20791, Rev. C, June 2001
Figure 2-3 shows some of the most commonly used parameters and their locations in the Summary Area.
The text following the figure gives a brief description of the parameters and, where applicable, refers you
to sections of the manual where complete definitions can be found.
The descriptions of the Channel Summary entries are as follows: (clockwise, top to bottom.)
Channel, Mode, and Sensor
These three items will always be present in the Summary Area. CH will be followed by 1, 2, 3, or 4 to
indicate the channel number. SW, PK and CW show whether the swept, Peak or CW mode is in use,
and A, B, or C indicates which sensor is assigned to the channel.
PATH CAL
This PC indication specifies that path calibration data is being subtracted from the swept measurement
reading. See Section 2.8.2 for a complete description of the use of path calibration.
Cursor, Power Value, and Unit
Indicates the power value being read at the cursor location on the displayed trace. The reading can be in
dB or mW units.
