8. Set the resistance and capacitance standards
to the values given in line 1 of Table 5-10.
Verify that the DQ display is within the range
given, inclusive. Lock in this range on the
1693 by pressing [SHIFT][HOLD RNG].

9. Continue down the table , verifying each
line. Because the capacitance in the series
equivalent circuit is different from the decade
capacitor setting when the series resistance
is large, use the RLC readout to indicate ca-
pacitance in those lines of the table.

Verify the Digibridge performance with regard to
limit comparison and bin assignments as follows. The
resistance standard 1433-33 or equivalent is required
for this test.

2. Connect the 1657-9600 extender cable from
the Digibridge remote test fixture as follows:
• "high" leads (red and red/white) to resis-
tor H
• "low" leads (black and black/white) to
resistor L
• "ground" lead (black/green) to resistor G
3. Refer to Table 5-11. After making the se-
quence of key-strokes (using the appropriate
limit entry keys) shown under "Entry", verify
that the Digibridge numerical displays are
like the numbers tabulated in the same row of
the table under "Displays". Make all entries
as tabulated.
4. Select on the Digibridge:
• FUNCTION: MEASURE
• DISPLAY: BIN No.
5. Refer to Table 5-12 For each setting of the
resistance standard, verify that the DQR
display is blank, the bin (RLC) display is a
single digit as tabulated, and the GO/NO-GO
lights work as tabulated.
