TEST WAVEFORM AND VOLTAGE SETUPS
WAVEFORM MEASUREMENTS
On the left-hand pages preceding the schematic
diagrams are test waveform illustrations that are
intended to aid in troubleshooting the instrument. To test
the instrument for these waveforms, make the initial
control settings as follows:

Changes to the control settings for specific waveforms
are noted at the beginning of each set of waveforms.
Input signals and hookups required are also indicated, if
needed, for each set of waveforms.
DC VOLTAGE MEASUREMENTS
Typical voltage measurements, located on the schematic
diagram, were obtained with the instrument operating
under the conditions specified in the Waveform
Measurement setup. Control-setting changes required
for specific voltages are indicated on each waveform
page. Measurements are referenced to chassis ground
with the exception of the Preregulator and Inverter
voltages on diagram 9. Those voltages are referenced as
indicated on the schematic diagram.
RECOMMENDED TEST EQUIPMENT
Test equipment listed in Table 4-1 in the "Performance
Check Procedure" section 4 of this manual, meets the
required specifications for testing this instrument.
