Simple Response Cals - Keysight N9913A User Manual

Calibration for NA, CAT, and VVM Modes
— Press
'Unknown THRU': When prompted: "Connect port 1 to port 2", then
connect port and port 2, using a coaxial cable or an appropriate thru
adapter. Do NOT use the internal ECal THRU, because the ECal thru
calibration model is incorrect for this calibration type.
'Flush THRU': When prompted: "Connect port 1 directly to port 2", then
you must connect the ports directly together at the calibration reference
plane with no adapter or other cabling.

Simple Response Cals

Simple Response Cals are used to quickly calibrate the magnitude and phase
of a measurement using any Open, Short, or Thru component. These may be
calibration standards, but because a Cal Kit is not selected, they are not
modeled. Measurement accuracy is generally low. Use a Simple Response Cal
to make quick measurements when using a jumper cable to connect the DUT
to the FieldFox. Otherwise, CalReady is usually more accurate.
You can perform a Simple Response Cal for either: S11, or S22, or S21 AND
S12.
When prompted, choose a standard based on the displayed measurements to
be calibrated. For example, to calibrate S11, connect either an OPEN or
SHORT to the port 1 reference plane.
When Simple Response Cals are performed, the source match and reflection
tracking terms from CalReady are updated by the measured Short or Open that
is used during the calibration.
1-port response cals are also available from the Mechanical Cal menu. Learn

not. Without extended cal, if you adjust your frequency outside the
calibrated range after the calibration has been completed, the error
correction is turned off.
— OFF (default) The FieldFox does not measure any frequency points
outside the current displayed frequency range. If the frequency is
adjusted outside of the set of points calibrated the error correction is
turned off and the following message is displayed:
"Error correction disabled. Stimulus outside
calibrated range."
Start Calibration. When prompted, verify the ECal module
connection, then press Measure. The standards within the ECal module are
automatically connected and measured.
