Tektronix 2230 Service Manual

Performance Check Procedure—2230 Service
c. Set the generator to produce a 1 MHz, 5-division
display.
d. CHECK—Display aberrations are within 4% (0.2
division or less) for the following VOLTS/DIV switch set
tings: 5 mV through 50 mV. Adjust the generator output
and attach or remove the 10X attenuator as necessary to
maintain a 5-division display at each VOLTS/DIV switch
setting.
e. CHECK—Display aberrations are within 6% (0.25
division or less) for the following VOLTS/DIV switch set
tings: 0.1 V through 0.5 V. Adjust the generator output
and attach or remove the 10X attenuator as necessary to
maintain a 5-division display at each VOLTS/DIV switch
setting.
f. Disconnect the cable from the CH 1 OR X input con
nector. Reconnect the 10X attenuator (if previously
removed) and reduce the generator amplitude to minimum.
g. Connect the cable to the CH 2 OR Y input connec
tor and set the VERTICAL MODE switch to CH 2.
h. Set the generator to produce a 5-division display.
i. Repeat parts d and e using the Channel 2 controls.
7. Check Store Aberrations
a. Reconnect the 10X attenuator and 50 £1 termination
(if previously removed) and reduce the generator amplitude
to minimum.
b. Set the CH 2 VOLTS/DIV switch to 2 mV.
c. Set the generator to produce a 5-division display.
d. Set:
STORE/NON STORE STORE (button in)
SAVE/CONTINUE CONTINUE (button out)
e. Allow acquisition cycle to complete and press in the
SAVE/CONTINUE button to SAVE (button in).
f. CHECK—Display aberrations are wjthin 4% (0.2 divi-
l sion or less).
g. Repeat part f for each of the following VOLTS/DIV
switch settings: 5 mV through 0.5 V. Adjust the generator
output and attach or remove the 10X attenuator as neces
sary to maintain a 5-division display at each VOLTS/DIV
switch setting.
h. Disconnect the cable from the CH 2 OR Y input con
nector. Reconnect the 10X attenuator (if previously
removed) arid reduce the generator amplitude to minimum.
i. Connect the cable to the CH 1 OR X input connector
and set the VERTICAL MODE switch to CH 1.
j. Set the generator to produce a 5-division display.
k. Repeat parts e and f using the Channel 1 controls.
I. Disconnect the test equipment from the instrument.
8. Check Bandwidth
a. Set:
VOLTS/DIV (both) 2 mV
A SEC/DIV 0.2 ms
STORE/NON STORE NON STORE (button out)
b. Connect the leveled sine-wave generator output via
a 50 fl cable and a 50 £2 termination to the CH 2 OR Y
input connector.
c. Set the generator to produce a 50 kHz, 6-division
display.
d. CHECK—Display amplitude is 4.2 divisions or
greater as the generator output frequency is increased up
to the value shown in Table 4-4 for the corresponding
VOLTS/DIV switch setting.
