Tektronix 2230 Service Manual

Performance Check Procedure— 2230 Service
e. Repeat parts c and d for all indicated CH 2
VOLTS/DIV switch settings, up to the output-voltage
upper limit of the sine-wave generator being used.
f. Move the cable from the CH 2 OR Y input connector
to the CH 1 OR X input connector.
g. Set the VERTICAL MODE switch to CH 1.
h. Repeat parts c and d for all indicated CH 1
VOLTS/DIV switch settings, up to the output-voltage
upper limit of the sine-wave generator being used.
10. Check Single Sweep Sample Acquisition
a. Set:
VERTICAL MODE
A SEC/DIV
X I0 Magnifier
A TRIGGER Mode
A&B INT
SAVE/CONTINUE
1K/4K
CH 1
5 M s
Off (knob in)
NORM
CH 1
CONTINUE (button out)
1K (button in)
b. Set the generator to produce a 50 kHz, 6-division
display.
9. Check Repetitive Store Mode and Bandwidth
a. Set:
c. Set:
Channel 1 AC-GND-DC GND
CH 1 VOLTS/DIV 10 mV A TRIGGER SGL SWP
A SEC/DIV 0.2 ms
b. Set the generator to produce a 50 kHz, 6-division
display.
c. Set:
A SEC/DIV 0.05 ms
X I0 Magnifier On (knob out)
d. Set the generator output to 2 MHz.
e. Set the AC-GND-DC switch to DC.
f. CHECK—The minimum peak-to-peak envelope
amplitude is greater than 5.6 divisions.
d. Set the generator to produce a 100 MHz display.
e. Set:
STORE/NON STORE STORE (button in)
SAVE/CONTINUE CONTINUE (button out)
NOTE
Allow the points to accumulate for a few seconds
before saving the display.
f. CHECK—The 100 MHz display will accumulate and
store.
11. Check Bandwidth Limit Operation
a. Set:
BW LIMIT On (button in)
CH I VOLTS/DIV 10 mV
AC-GND-DC DC
A SEC/DIV 20 ms
A TRIGGER P-P AUTO
A&B INT VERT MODE
STORE/NON STORE NON STORE (button out)
b. Set the generator to produce a 50 kHz, 6-division
display.
g. CHECK—Display amplitude is 4.2 divisions or
greater.
h. Set the VERTICAL MODE switch to BOTH and
ALT.
c. Increase the generator output frequency until the
display amplitude decreases to 4.2 divisions.
d. CHECK—Generator output frequency is between 18
and 22 MHz.
i. Repeat parts f and g.
e. Disconnect the test equipment from the instrument.
