(3) Set the function generator as listed in (a) through (e) below.
(a)
Sine wave
(b)
1 V rms
(c)
1 MHz
50 Ω output impedance selected
(d)
(e)
Output, ON
(4) TI will indicate between 0.999,988 MHz and 1.000,012 MHz. If not, perform b below.
(5) Set function generator output to OFF and disconnect equipment set-up.
b. Adjustments. Complete all performance checks in the entire procedure noting AS
FOUND failures. Use paragraph 15 g for adjustments.
15. Alignment
NOTE
Non-Volatile Input Offset Compensation is used only when the
input zero capability is not in use. Non-Volatile Input Offset
Compensation adjustment in step h does not affect any other
adjustments. Adjustment should be considered if any other
parameter(s) are adjusted. There is no performance check or
specification associated with Non-Volatile Input Offset
Compensation.
Adjustment is at the discretion of the
technician.
a. ADC Adjustments
(1) Set the rear panel CALIBRATION switch to ENABLE.
(2) Ensure that nothing is connected to the front or rear INPUT terminals.
(3) Press TI keys as listed in (a) through (c) below.
(a) CAL
(b) [SPECIAL]
(c) [ADC]
(4) Automatic adjustment will take approximately 3 minutes and is complete when
the BUSY legend goes out.
(5) Exit CAL menu by pressing [QUIT] 3 times.
b. DC Voltage Adjustments
NOTE
Just one range may be adjusted if required, but for a full
adjustment, start with the 200 mV range and work up to the
1kV range. Zero cal point on all ranges requiring adjustment
may be completed before any range gain adjustments to avoid
multiple connect/disconnects. Any range requiring adjustment
must have all three adjustments: Zero, Range Gain + and
Range Gain .
