Receiver calibration
Receiver calibration gives corrected absolute power reading (for
unratioed traces as opposed to an S-parameter traces)
Often used with FOM for measurements like harmonics, TOI
Uses power-meter-corrected internal source as a reference
(source power cal)
Now saved as a cal set
Multiple receiver cals requires
separate channels for each cal
Source power calibrations
• No change from current behavior
• Saved as part of instrument states
• Not saved in cal sets
New!

Correction Indicator on Status Bar
C - Full correction
“C” is displayed immediately after a calibration is performed
or when a valid Cal Set is applied. If you require optimum
accuracy, avoid adjusting the analyzer’s settings after calibration.
C* - Interpolated correction
"C*" appears in the status bar when interpolation is used during a measurement.
C∆ − Changed settings
"C∆" appears in the status bar when one or more of the following stimulus settings change. The
resulting measurement accuracy depends on which parameter has changed and how much it has
changed. For optimum accuracy, recalibrate using the new settings.

• IF bandwidth
•Port power
