7. Equipment Setup
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUPUT(S) to minimum after each step within the performance
check where applicable.
CAUTION
Before connecting TI to power source, make sure TI is set to the
power source line voltage as shown on rear of TI.
a. Connect TI to 115 V ac power source.
b. Press power key to on and allow at least 30 minutes for TI to reach
operating temperature.
8. Time Base Accuracy
a. Performance Check
(1) Set TI 10.000 MHz source switch (rear panel) to INT.
(2) Connect TI OUT 50Ÿ (rear panel) to frequency counter channel A.
(3) Set up frequency counter to measure frequency to 1 Hz resolution.
(4) If frequency counter does not indicate within limits specified in table 3, perform
b below.

b. Adjustments (option 3 only)
(1) Press and hold down the TI BSP key, then press and release the TI STORE key.
(2) Release the TI BSP key.
(3) Use the TI left/right (4, 6) and the TI up/down (8, 2) cursor control keys to adjust
the displayed value until the frequency counter indicates 10.000000 MHz 1 Hz.
9. Output Amplitude
a. Performance Check
(1) Connect TI T0 output to oscilloscope Vertical 1 input.
(2) Press TI keys as listed in (a) through (f) below:
