a. Performance Check
(1) Set TI SECONDS/DIV switch to .5 ms.
(2) Set TI CH 1 and CH2 VOLTS/DIV switches to 10m.
(3) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI CH 1 and
CHAN 2 to TI CH 2.
(4) Set oscilloscope calibrator VOLTAGE output to 50 mV, 1 kHz.
(5) Adjust TRIGGERING LEVEL and POSITION controls, as necessary, to
view waveform.
(6) Adjust INTEN and FOCUS controls for suitable viewing.
(7) Rotate oscilloscope calibrator EDIT FIELD knob for 5 divisions of vertical
deflection. If oscilloscope calibrator err display readout does not indicate within r2%,
perform b (1).
(8) Repeat technique of (1) through (7) above for settings listed in table 5.
Oscilloscope calibrator err display readout will indicate within r2%.
(9) Set TI DISPLAY and SOURCE switches to CH 2.
(10) Activate oscilloscope calibrator CHAN 2 output and repeat technique of (1)
through (7) above for CH 2. If oscilloscope calibrator err display readout does not indicate
within limits specified, perform b (2).
