This chapter provides adjustment information for the 2074 dual
channel waveform generator.
The procedures described in this section are for use only
by qualified service personnel. Many of the steps covered
in this section may expose the individual to potentially
lethal voltages that could result in personal injury or death
if normal safety precautions are not observed.
ALWAYS
PERFORM
CLEANING AT A STATIC SAFE WORKSTATION.
Do not attempt to calibrate the instrument before you verify that there
is no problem with the functionality of the product. A complete set of
specification is listed in Appendix A. If the instrument fails to perform
within the specified limits, the instrument must be tested to find the
source of the problem.
In case there is a reasonable suspicion that an electrical problem
exist within the 2074, perform a complete performance checks as
given in Chapter 6 to verify proper operation of the instrument.
The 2074 can operate from 0°C to 50°C. Adjustments should be
performed under laboratory conditions having an ambient temperature
of 25°C, ±5°C and at relative humidity of less than 80%. Turn on the
power to the 2074 and allow it to warm up for at least 30 minutes
before beginning the adjustment procedure. If the instrument has been
subjected to conditions outside these ranges, allow at least one
additional hour for the instrument to stabilize before beginning the
adjustment procedure.
Most equipment is subject to a small amount of drift when it is first
turned on. To ensure accuracy, turn on the power to the Model 2074
and allow it to warm-up for at least 30 minutes before beginning the
performance test procedure.
