(8) Measure output. If oscilloscope does not indicate within limits shown in T0/VAR
(9) Select TI T0 output ECL mode by pushing 4.
(10) Configure oscilloscope for a base measurement and measure T0 ECL output. If
oscilloscope does not indicate within limits shown in T0/ECL row of table 4, perform b below.
(11) Disconnect oscilloscope Vertical 1 input from TI T0 output.
(12) Connect TI A output to oscilloscope Vertical 1 input.
(13) Repeat technique of (3) through (11) for TI output A. If oscilloscope does not
indicate within limits specified, perform b below.
(14) Repeat technique of (11) through (12) above for TI remaining output modes
listed in table 4. If oscilloscope does not indicate within limits specified, perform b below.
b. Adjustments

(6) Disconnect oscilloscope Vertical 1 input from TI T0 output.
(7) Connect oscilloscope Vertical 1 input to TI A output.
(8) Press and hold down the TI BSP key then press and release the TI GPIB key
until TI display indicates Amplitude A
###.
(9) Release the TI BSP key.
(10)Use the TI left/right (4, 6) and the up/down (8, 2) cursor control keys to adjust
the displayed value until the oscilloscope waveform amplitude is 0.800 Vpp (R).
(11) Disconnect oscilloscope Vertical 1 input from TI A output.
(12) Connect oscilloscope Vertical 1 input to TI B output.
(13) Press and hold down the TI BSP key then press and release the TI GPIB key
until TI display indicates Amplitude B
###.
(14) Release the TI BSP key.
(15) Use the TI left/right (4, 6) and the up/down (8, 2) cursor control keys to adjust
the displayed value until the oscilloscope waveform amplitude is 0.800 Vpp (R).
(16) Disconnect oscilloscope Vertical 1 input from TI B output.
