Performance Check Procedure— 2236 Service
l. Repeat parts c and d.
m. Increase the generator output voltage to 300 mV.
g. CHECK— Display is triggered along the entire nega
tive slope of the waveform as the A TRIGGER LEVEL con
trol is rotated.
n. CHECK— The readout is stable and accurately dis
plays the input signal frequency.
h. CHECK— Display is not triggered (no trace) at either
extreme of rotation.
o. Disconnect the test equipment from the instrument.
4. Check Single Sweep Operation
a. Set the A SOURCE switch to INT.
b. Adjust the A TRIGGER LEVEL control to obtain a sta
ble display.
3. Check External Trigger Ranges
a. Set:
c. Set the Channel 1 Input Coupling switch to GND.

d. Press in the SGL SWP button. The READY LED
should illuminate and remain on.
e. Set the Channel 1 Input Coupling switch to DC.
b. Connect the leveled sine-wave generator output via a
50-0 cable, a 50-0 termination, and a dual-input coupler to
both the CH 1 OR X and EXT INPUT connectors.
f. CHECK— READY LED goes out and a single sweep
occurs.
c. Set the generator to produce a 50-kHz, 6.4-division

display.
The A INTENSITY control may require adjustment to
observe the single-sweep trace.
d. CHECK— Display is triggered along the entire positive
slope of the waveform as the A TRIGGER LEVEL control is
rotated.
g. Press in the SGL SWP button several times.
e. CHECK— Display is not triggered (no trace) at either
extreme of rotation.
h. CHECK— Single-sweep trace occurs, and the READY
LED illuminates briefly every time the SGL SWP button is
pressed in and released.
f. Set the A TRIGGER SLOPE button to IN.
i. Disconnect the test equipment from the instrument.
