Verifying the Wideband AC Option

Wideband verification verifies that the 5790B WIDEBAND input (requires Option
5790B/3, 5790B/5, or 5790B/AF) is within tolerance. There are two worksheets
and one test record to facilitate this procedure. You will need 1 copy of Table 3-
15, 8 copies of Table 3-16 (one for each voltage range) and 1 copy of the overall
test record, Table 3-17.
If verifying Option 5790B/3, frequencies above 30 MHz are not
applicable.
