Check Riseifall Lnput Impedance: 50 Q. + 3%. 1 Mq. 500 Kq - Tektronix DC 5010 Anleitung

Calibration-DC 501 0
Performance Check Procedure
s. Note the DC 5010 display readout (peak input
voltage).
t. Divide the readout on step 6p by the readout on step
6s.
u. CHECK-that the ratio between the two readings is
between 1.03 and 1.13 (ratio of input capacitance to the
20 pF normalization).
7. Check RISEIFALL lnput Impedance: 50 O,
+3%, 1 MO, 500 kO, +2% (60 MHz sinewave at
high level)
Refer to Fig. 4-2, performance check setup.
a. Set the digital multimeter Function Range switch to
2 kQ.
b. Press the DC 501 0 CHANNEL A ATTEN X I button
(lighted) and the 50 52 button (lighted), and press to light the
RISEIFALL A button.
c. CHECK-that the digital multimeter display readout
indicates between .0490 and .0510.
d. Press both DC 5010 CHANNEL A and B TERM 1 MQ
buttons (unlighted).
e. Change the digital multimeter Function-Range switch
to 2000 kQ.
f. CHECK-that the digital multimeter display readout
indicates between .4900 and 5 1 00 (kQ).
8. Check the lnput Sensitivity: X I Attenuation, DC
-
and AC Coupled; 50 O, ~ 7 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

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 BIA but-
ton (lighted).
g. Press the DC 5010 AUTO TRlG button, LEVEL CH B
button, and the DISPLAY-TEST button.
