371B Service Manual
Test Equipment
The test equipment listed in Table 5–1 is required for a complete performance
check and adjustment of the instrument. However, complete checking or
adjustment may not always be necessary or desirable. You may be satisfied with
checking only selected characteristics, thereby reducing the amount of test
equipment actually required.
The specifications for test equipment listed in Table 5–1 are the minimum
required to check performance requirements of the 371B. Detailed operating
instructions for test equipment are not given in these procedures; refer to the test
equipment instruction manual if more information is needed.
