Tektronix 2467B Service Manual

Performance Check—2465B/2467B Service
f. Set the generator output level for a 0.7-division
display at the reference frequency (50 kHz).
3. Check Trigger Noise Rejection — All Channels.
a. Set:
g. Connect the Secondary Leveled Sine-Wave Genera-
tor to the CH 4 input using a BNC cable and a 50 fi
termination.
NOTE
Select channels to set VOLTS/DIV.
h. Set TRIGGER SOURCE to CH 4.
i. Set the generator output level for a 0.7-division
display at the reference frequency.
i. Set TRIGGER SOURCE to VERT.
k. CHECK—Display will trigger as the TRIGGER
LEVEL control is rotated through its range.
CH 1 VOLTS/DIV 5 mV
CH 2 VOLTS/DIV 50 mV
CH 3, CH 4 VOLTS/DIV 0.1 V
CH 1 VERTICAL MODE On
CH 2, CH 3, CH 4
VERTICAL MODE Off
CH 1 and CH 2
Input Coupling 1 MS) DC
ASEC/DIV 10 MS (knob in)
TRIGGER MODE AUTO LVL
TRIGGER SOURCE VERT
I. Pull the SEC/DIV knob out, rotate it to 5 MS, and push
it back in.
b. Connect the Function Generator to the CH 1 input
via a 50 Q BNC cable and a 10X attenuator.
m. Press the A/B TRIG button and set the B TRIGGER
MODE to TRIG AFT DLY.
c. Set the Function Generator output frequency and
level for a 50-kHz, 4-division display.
n. Set B TRIGGER SOURCE to VERT.
d. Set the CH 1 VOLTS/DIV to 50 mV.
NOTE
On CTT Instruments, rotate the A HEF OR DLY
POS control for the specified delay. As the control is
rotated, the readout delay value will be followed by
the word "SET". This value shows the approximate
delay. A few seconds after control movement has
stopped, the word "SET" will disappear and the
readout delay value as measured by the CTT will
appear. This is normal operation and not cause for
concern.
e. Set the TRIGGER COUPLING to NOISE REJ.
f. CHECK—Display will not trigger (freeruns).
g. Pull the SEC/DIV knob out, rotate it to 5 us and
push it back in.
h. Press the A/B TRIG button to select the B
TRIGGER.
o. Rotate the A REF OR DLY POS control CCW until
the delay readout indicates DLY? 0.00 us.
Set the TRIGGER MODE to B TRIG AFT DLY.
p. CHECK—Display will trigger as the TRIGGER
LEVEL control is rotated through its range.
q. Rotate the SEC/DIV knob back to 10 MS (knob in)
Set TRIGGER COUPLING to NOISE REJ.
k. CHECK—Display will not trigger for any setting of
the LEVEL control.
r. Disconnect the test setup.
I. Rotate the SEC/DIV back to 10 MS (knob in).
