16362A DUT Box as shown in Figure 5-12 (a). If DUT Box is not available, attach
16061A Test Fixture to 4262A UNKNOWN terminals [see Figure 5-12 (b)].
b. Set 4262A controls as follows:
DCBIAS......... .. i OFF
SELFTEST............... ... ... ... OFF
FUNCTION. ....... ..ottt C
CIRCUITMODE. ...................... PRL
LOSS. ... D
TESTSIGNAL . ............ ..., 10kHz
LCRRANGE ...........c.oiiviiiean, AUTO
DQRANGE .......... ... .. ot AUTO
TRIGGER........... ... .o, INT
c. Rotate both C and L ZERO ADJ controls fully cw.
d. Set 16362A LCR RANGE to 1000pF D = 1.8 or connect the following sample, as an
alternate DUT, to 16061A:
DUT Values of components
C
_Du_ C: 1000pF (HP P/N: 0160-3766)
R R: 10kQ (HP P/N: 0698-6360)
e. Adjust capacitor A13C1 for the calibrated value of the 16362A (or DUT) 3 counts on
4262A DQ display.
Note
If this adjustment fails to bring dissipation
factor readout to within the tolerance, change
A13C1 to 5.5/18pF capacitor (HP P/N: 0121-
