Calibrating for Increased Measurement Accuracy
Enhanced Frequency Response Error Correction
12.To measure the standard, when the displayed trace has settled, press:
, select the type of load you are using, and then press when
the analyzer has finished measuring the load.
Notice that the softkey is now underlined.
13.To compute the reflection correction coefficients, press .
14.To start the transmission portion of the correction, press .
15.Make a "thru" connection between the points where you will connect your device under
test as shown in Figure 6-7.
NOTE Include any adapters or cables that you will have in the device measurement.
That is, connect the standard device where you will connect your device under
test.
NOTE The thru in most calibration kits is defined with zero length. The correction
will not work properly if a non-zero length thru is used, unless the calibration
kit is modified to change the defined thru to the length used. This is
important for measurements of non-insertable devices (devices having ports
that are both male or both female). The modified calibration kit must be
saved as the user calibration kit, and the softkey must be
selected before the calibration is started.
16.To measure the standard, when the trace has settled, press:
or
or
The analyzer underlines the softkey label after it makes each measurement.
17.Press and select from the following two options:
❏ If you will be measuring devices with a dynamic range less than 90 dB, press:
❏ If you will be measuring devices with a dynamic range greater than 90 dB, follow
these steps:
a. Connect impedance-matched loads to the test ports. Include the adapters that you
would include for your device measurement.
NOTE If you will be measuring highly reflective devices such as filters, use the test
device, connected to the reference plane and terminated with a load, for the
isolation standard.
