VOLTAGE CONDITIONS
The 7D11 under test must be connected to a mainframe separate from the test oscilloscope. No signal is
applied for voltage measurements. Voltmeter common is connected to chassis ground.

Front panel controls are set the same as for voltage measurements. The time mark generator
10-microsecond triggers are applied to the 7D11 EVENTS START TRIG IN connector. Except where "-
noted, the test oscilloscope is externally triggered from the 10-microsecond signal from the time mark
generator.
