173x Auxiliary Input Adapter Verification (1732/1734/1736/1738 Only)
The Auxiliary Input Adapter has a 1000:1 divider that can be verified with a calibrator and an 8846A.
To connect to the Connector pins, use a banana-to-pin adapter (Pomona Electronics 4690 is
recommended). See Table 15 and Table 16.
