9-18 Section 9: Verifying the Model 9500B Accuracy Specification
Final Width = 215mm
9.8.6.1 Summary
Equipment requirements are given at para 9.8.6.2 and test
interconnections at para 9.8.6.3.
The Pulse Width Function is verified by carrying out measurements of
Period in the sequence given at paras 9.8.6.5, at the verification points
shown in Table 9.8.6.1.
9.8.6.2 Equipment Requirements
• The UUT Model 9500B Mainframe, with 9510 or 9530 Active
Head.
• Digital counter for 0.25ppm clock accuracy measurements.
Example: Hewlett Packard Model HP53131A with Option 012.
9.8.6.3 Interconnections
Refer to Fig 9.8.6.1.
9.8.6.4 Verification Setup
1. Connections Connect the 9500B to the Counter as shown in Para
