8. Vertical Gain
a. Performance Check
(1) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 and CHAN 2 to
TI CH 1 and CH 2 inputs respectively.
(2) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 5 mV at
1 kHz frequency.
(3) Rotate oscilloscope calibrator knob below EDIT FIELD pushbutton to adjust
amplitude for 5 divisions of deflection on TI. If oscilloscope calibrator err display does not
indicate within limits specified in first row of table 3, perform b (1) and (2) below.
(4) Repeat technique of (2) and (3) above for settings listed in table 3. Oscilloscope
calibrator err display will indicate within limits specified in table 3.
