NOTE
Do not handle yellow printed circuit board except at extreme
edges. Fingerprints on this board may degrade instrument
performance.
b. Mount a calibrated TD-1209/U (Hewlett-Packard, Model 5300A) measuring system
on TI and orient the interconnected units upside down.
c. Connect measuring system to
autotransformer and connect autotransformer to a
115 V
ac source.
e. 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 (g) below:
(a)
COM-SEP-CHK switch to SEP.
(b)
A and B ATTEN switches to X1.
(c)
A and B AC/DC switches to DC.
(d)
A and B SLOPE switches to +.
(e)
A and B LEVEL controls ccw to PSET.
(f)
Function switch to 10S.
(g)
DELAY switch ccw to OFF.
(2) Connect function/arbitrary generator output to TI A 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. If function/arbitrary generator output
exceeds 25 mV, perform b (1) through (3) below.
(5) Repeat technique of (3) and (4) above at function/arbitrary generator frequencies
of 100 Hz; 1, 10, and 100 kHz; and 1 MHz.
NOTE
Set function switch to 1S for 100 kHz check and .1S for 1 MHz
check.
(6) Set TI function switch to AUTO and repeat technique of (3) and (4) above at
function/arbitrary generator frequency of 10 MHz. If function/arbitrary generator output
exceeds 50 mV and no adjustment was previously made, perform b (1) through (3) below.
(7) Adjust function/arbitrary generator for 10 kHz and minimum output.
