TEST WAVEFORM AND VOLTAGE SETUPS
WAVEFORM MEASUREMENTS
On the left-hand pages preceding the schematic
diagram s are test waveform illustrations that are intended
to aid in troubleshooting the instrument. To test the instru
ment for these waveform s, make the initial control settings

Changes to the control settings for specific waveforms
are noted at the beginning of each set of w aveform s. Input
signals and hookups required are also indicated, If needed,
for each set of waveforms. Voltage m easurements are
made with a IX probe unless otherwise noted.

DC VOLTAGE MEASUREMENTS
Typical voltage measurements, located on the
schematic diagram, w ere obtained with the instrument
operating under the conditions specified in the W aveform s
Measurem ents setup. Control-setting changes required for
specific voltages are indicated on each waveforms page.
Measurements are referenced to chassis ground w ith the
exception of the Preregulator and Inverter voltages on
Diagram 8. These voltages are referenced as Indicated on
the schematic diagram.
RECOMMENDED TEST EQUIPMENT
Test equipment in Table 4-1 m eets the required
specifications for testing this instrument.
