4. Verify that each amplitude measurement is within the range speci fi ed in the
test record table.
5. Record the results in the test record.

outputs.
7. Record the results in the test record.
DC Offset and Vocm tests
This test should be done once in Basic mode and once in Advanced mode to
verify the DC offset and Vocm accuracy of the generator. This test uses a 50
Ω
terminator. It is necessary to know the accuracy of a 50 Ω terminator in advance
of this test. This accuracy is used for as a calibration factor.
Basic mode
1. Connect the 50 Ω terminator to the DMM as shown in the following fi gure
and measure the register value.

2. Calculate the 50 Ω calibration factor (CF) from the reading value and record
as follows:
CF (Calibration Factor) = 2
