NOTE
Paragraphs b through d below comprise the verification test
for the wideband option. Paragraph e below is the flatness
calibration procedure. Performance of e below is only required
if an out-of-tolerance condition exists in b and d below or upon
paragraphs a above and c below must be completed prior to d
and e below in order to establish, or characterize, voltage
accuracies at 1 kHz. If an out-of-tolerance condition exists in c
below, repeat a above and c below. If an out-of-tolerance
condition still exists, a repair action is required.
b. Frequency Accuracy
(1) Connect wideband output to frequency counter CHANNEL A input, using
termination and cable supplied with TI. Set TI for a 0 dBm, 10 Hz wideband output.
(2) Measure output frequency; frequency counter will indicate between 99.99 and
100.01 ms.
(3) Adjust TI frequency to those listed in table 9. At each frequency setting repeat
(2) above. Frequency counter will indicate within the listed limits.
(4) Press RESET pushbutton.
