a. Mount a calibrated TD-1209/U (Hewlett-Packard, Model 5300A) measuring system
on TI.
b. Connect measuring system to
autotransformer and connect autotransformer to a
115 V
ac source.
d. Adjust measuring system SAMPLE RATE control cw to ON position and allow 1
hour for warm-up.
a. Performance Check
(1) Position controls as listed in (a) through (c) below:
(a) GATE switch to 10S.
(c) SENSITIVITY control fully cw.
(2) Connect function/arbitrary generator output to TI INPUT, using termination.
amplitude to minimum output.
(4) Slowly increase function/arbitrary generator amplitude until measuring system
indicates a stable count of the applied frequency. Function/arbitrary generator output will
not exceed 50 mV.
(5) Adjust frequency of function/arbitrary generator for 50 Hz and amplitude to
minimum output.
(6) Slowly increase function/arbitrary generator amplitude until measuring system
indicates a stable count of the applied frequency. Function/arbitrary generator output will
not exceed 25 mV.
(7) Repeat technique of (5) and (6) above at function/arbitrary generator frequencies
of 100 Hz; 1, 10, and 100 kHz; and 1 MHz.
NOTE
Set GATE switch to 1S for 100 kHz check and .1S for 1 MHz check.
(8) Set GATE switch to AUTO and repeat technique of (3) and (4) above at
function/arbitrary generator frequency of 10 MHz.
b. Adjustments. No adjustments can be made.
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA Label/Form in accordance with TB 750-25.
