than 20 volts; pulse top flatness, within 0.5% after
750 nanoseconds; negative-going square-wave referenced to
zero volts.
Recommended equipment: Tektronix Type 106
Square-wave Generator.
2. Precision DC voltage supply: Output, 20 volts DC;
accuracy, within 0.05%; ripple, less than 1 millivolt.
Recommended equipment: Fluke 343A DVM Calibrator.
Adjustment Procedure
1. Insert the M2 Module into the 7D12 AID Converter
and install in the left vertical compartment of a 7000-series
oscilloscope.
2. I nstall a delaying time-base in the A Horizontal
compartment and a time-base into the B Horizontal
3-6
compartment of the oscilloscope. (One dual time-base such
as the 7B53A can be substituted in place of the two
time-bases.)
3. Connect the oscilloscope to a power source that
meets the voltage and frequency requirements of the
oscilloscope power supply.
4. Turn the oscilloscope power on and allow about
twenty minutes warmup time.
5. During the warmup period, set the controls as
follows.
