5. Connect each standard (short, open and load) in turn and click appropriate Standard button (in
Calibration window)
6. Connect ends of test cables together and click Through
7. Connect 50 Ω load to the ends of test cables (to perform the isolation step) and select Isolation (in
Calibration window)
8. Click Apply (in Calibration window)
9. If desired, for later use, save calibration ( File > Save Cal )
10. Connect device to be tested and click Start
Tips:
For best linearity and dynamic range combination, use a test power level of 0 dBm
For best dynamic range use a test power level of +6 dBm and calibrate using the same bandwidth you
intend to use for your measurements – particularly at the
isolation calibration step
6.2.5 Calibration steps for all S-parameters measurements
(insertable DUT)
This calibration provides full error correction for all S-parameters. Typical steps are as follows:
1. Select the calibration kits ( Tools > Calibration kits > Load P1 Kit > Load P2 Kit >Apply )
2. Set the bandwidth and test power ( Enhancement button)
3. Set the frequency range and measurement steps ( Calibration button)
4. Select ’All –Insertable DUT’ calibration (in Calibration window)
5. Connect each standard (short, open and load) in turn and click appropriate Standard button (in
Calibration window)
6. Click Isolation select the first method on the left (isolation is measured with 50 Ω loads on each
calibration port which is the same as the load step in 5 above)
7. Connect ends of test cables together and click Through
8. Click Apply (in Calibration window)
9. If desired, for later use, save calibration ( File > Save Cal and Status )
10. Connect device to be tested and click Start
Tips:
For best linearity and dynamic range combination use a test power level of 0 dBm. Use the same
bandwidth as you will use during measurements.
For best dynamic range use a test power level of +6 dBm and calibrate using the same bandwidth
you intend to use for your measurements.
6.2.6 Calibration steps for all S-parameters measurements
(non-insertable DUT)
This calibration provides full error correction for all S-parameters. It requires a calibration kit with a
characterized through connection. Typical steps are as follows:
1. Select the calibration kit ( Tools > Calibration kits > Load P1 Kit > Apply )
2. Set the bandwidth and test power ( Enhancement button)
3. Set the frequency range and measurement steps ( Calibration button)
4. Select All – Non-insertable DUT calibration (in Calibration window)
5. Connect each reflection standard (short/open) in turn and click appropriate Standard button (in
Calibration window)
6. Click Load to measure the Load Standard (in Calibration window)
7. Connect ends of test cables together using the characterized through included in the calibration kit and
click Through
8. Click Apply (in Calibration window)
9. If desired, for later use, save calibration ( File > Save Cal and Status )
10. Connect device to be tested and click Start
