Response and Isolation Error-Correction for Transmission Measurements

This procedure is intended for measurements that have a measurement range of greater than 9 0 dB.

1.Press IpresetJ.

2.Select the type of measurement you want to make.

qIf you want to make a transmission measurement in the forward direction (&I), press:

qIf you want to make a transmission measurement in the reverse direction (E&2), press:

3.Set any other measurement parameters that you want for the device measurement: power, number of points, IF bandwidth.

4.‘lb access the measurement correction menus, press:

.

5.If your calibration kit is different than the kit specified under the ~~~~;~~~~~l,,::,,,,::~ softkey, press:

If your type of calibration kit is not listed in the displayed menu, refer to the “Modifying Calibration Kit Standards” procedure, located later in this chapter.

6.To select a response and isolation correction, press:

7.Make a “thru” connection between the points where you will connect your device under test.

Note Include any adapters that you will have in the device measurement. That is, connect the standard device to the particular connector where you will connect your device under test.

8. To measure the standard, when the displayed trace has settled, press:

The analyzer displays WAIT - MEASURING CAL STANDARD during the standard measurement.

.::.:....,x .,.,.,., ., ./

The analyzer underlines the !@##!&I?. softkey after it measures the calibration standard, and computes the error coefficients

9.Connect impedance-matched loads to PORT 1 and PORT 2, as shown in Figure 5-5. Include the adapters that you would include for your device measurement.
