Calibration-DC 50 10
Performance Check Procedure
9. Check the Input Sensitivity: X5 Attenuation, DC
and AC Coupled; 50 D ~ 3 5 0 mV p-p
Refer to Fig. 4-5, performance check setup. Use the fol-
lowing control settings.

a. Connect a coaxial cable with a 10X attenuator from
the sinewave generator output to the DC 501 0 CHANNEL A
input.
b. Press the DC 501 0 AUTO TRlG button, LEVEL CH A
button, and the DISPLAY-TEST button.
c. Press the DC 501 0 (increment) or (decrement) but-
tons to adjust the trigger level for a stable display readout.
d. CHECK-that the DC 501 0 display readout indicates
approximately 350.00XXXX (the last four digits can vary
due to source instability).
e. Move the DC 5010 CHANNEL A input connection to
the CHANNEL B input.
f. Connect the 1 MHz frequency standard to the
DC 5010 CHANNEL A input and press the RATIO B/A but-
ton (lighted).
g. Press the DC 501 0 AUTO TRlG button, LEVEL CH 6
button, and the DISPLAY-TEST button.
h. Press the DC 501 0 (increment) or
4
(decrement) but-
tons to adjust the trigger level for a stable display readout.
i. CHECK-that the DC 501 0 display readout indicates
approximately 350.00XXX (the last three digits can vary due
to source instability).
