(1) Connect function/arbitrary generator Output to TI INPUT HI and LO using 50
eedthrough termination.
(2) Press FREQ key.
(3) Set function/arbitrary generator for a sine wave, 20 Hz, 1 V rms output. If TI
does not indicate between 19.99000 and 20.01000 Hz, perform b below.
(4) Set function/arbitrary generator frequency to 1 MHz. If TI does not indicate
between 999.9000 kHz and 1.000100 MHz, perform b below.
