SOURCE OUTPUT
ACCURACY This test verifies the source output accuracy of the MS462XC. The test
procedure uses the Power ALC Verification built-in function of the
MS462XC Basic Measurement software.
Setup:
Step 1. Connect a GPIB cable between the power meter GPIB connec-
tor and the MS462XC dedicated GPIB connector, as shown in
Figure 6-1.
Step 2. Turn on the MS462XC VNMS and allow it to warm-up at
least one hour.
Test Procedure
Step 1. Disconnect cables between MS462XC Port 1 and Port 1 of
MS4782 Test Set and between Port 3 of MS462XC and Port 3
of MS4782 Test Set.
Step 2. Press Utility key and select:
