Example 2E: Adapter Removal Calibration

NOTE This program is only valid on ES model analyzers.

This program shows how to accurately measure a “non-insertable” 2-port device. A device

is termed “non-insertable” if its connectors do not match those of the analyzer front panel.

More information on the adapter removal technique can be found in your analyzer’s user’s

guide.

The following is an outline of the program's processing sequence:

• An I/O path is assigned for the analyzer.

• The system is initialized.

• The internal disk is selected as the active storage device.

• The system operator is prompted for the name of the instrument state file which has a

2-port calibration performed for Port 1's connector.

• The calibration arrays for Port 1 are recalled from the corresponding disk file.

• The system operator is prompted for the known electrical delay value of the adapter.

• The new calibration coefficients, with the effects of the adapter removed, are computed

by the analyzer using the adapter delay in conjunction with the calibration arrays for

both ports.

• The analyzer is released from remote control and the program ends.

CAUTION Do not mistake the line switch for the disk eject button. If the line switch is

mistakenly pushed, the instrument will be turned off, losing all settings and

data that have not been saved.

Running the Program

The analyzer is initialized and the internal disk drive is selected. The operator is queried

for the name of the instrument state file having a 2-port calibration performed for Port 1's

connector. The calibration arrays for Port 1 are recalled from the corresponding disk file.

The system operator is prompted for the name of the instrument state file having a 2-port

calibration performed for Port 2's connector. The calibration arrays for Port 2 are recalled

from the corresponding disk file. The system operator is prompted for the known electrical

delay of the adapter and this value is written to the analyzer. The calibration coefficients

with adapter effects removed are computed and the program ends.
