INSPECTION
The following procedures should be performed to as-
sure the user that the instrument has arrived at its
destination in satisfactory operating condition. Com-
plete calibration and checkout instructions are pro-
vided in Section 4 to determine compliance with elec-
trical specifications.
Checking Visually
After carefully unpacking the instrument, visually in-
spect the external parts for damage to knobs, dials,
indicators, surface areas, etc. If damage is discovered,
file a claim with the carrier who transported the in-
strument. Retain the shipping container and packing
material for use in case reshipment is required.
Checking Electrically
lnstrumen ts are normally shipped con-
nected for 115 V power unless 230 V
power is ordered. Refer to the end of
this section for conversion instructions.
The steps in this paragraph provide a quick checkout
of the instrument operation. If electrical deficiencies
exist, refer to the WARRANTY in the front of this
manual. The following test equipment is recommended
for performing this electrical inspection:
Name
Oscilloscope
Plug-l n
Plug-l n
Counter-Timer
1.
Turn FREQ HZ selector to the Xl K position.
(This connects ac power to the unit and estab-
lishes the frequency multiplier.)

2. Depress MODE - FUNC push button.
Connect oscilloscope to the
3.
tor with a terminator.
4. Set frequency dial to the 1.0 mark and FREQ
VERNIER to CAL position.
Set function selector to the
5.
Set OUTPUT ATTEN (dB) and OUTPUT VER-
6.
NIER (dB) to maximum clockwise (cw) posi-
tion (no attenuation).
Check for 1 kHz sine wave with at least 10 V
7.
p-p amplitude on oscilloscope.
8. Select and
and check for 10 V p-p amplitude on oscil-
loscope.
9. Turn frequency dial from maximum counter-
clockwise (ccw) to maximum cw position and
check for frequency change.
10.
Step OUTPUT ATTEN (dB) selector through
its range and verify attenuation at each step.
11.
Rotate OUTPUT VERNIER (dB) control from
maximum cw to maximum ccw position and
check for decreasing amplitude.
12. Rotate FREQ VERNIER control and check for
frequency change.
13. Set FREQ VERNIER control at maximum cw
and frequency dial at 0.02. Set frequency to
20 Hz with counter. Connect a 0 to +5 Vdc
input to the VCG IN connector. Slowly increase
voltage input from 0 to +5 V and check that
frequency of output waveform increases from
approximately 20 Hz to 2 kHz.
14.
Depress SEQUENCE LENGTH
button.
15. Set NOISE FREQ HZ selector to the 16K/160K
position and vernier control fully cw.
16. Connect a BNC cable from the NOISE SYNC
connector (rear panel) to the external trigger
input of the oscilloscope.
17. Rotate the function selector to
to assure oscilloscope displays digital noise.
18. Check to assure SEQUENCE LENGTH push
buttons vary the bits in the sequence length.
19. Step NOISE FREQ HZ selector through its
range and check to assure clock frequency
changes. (Use NOISE CLOCK connector on rear
panel.)
