Tektronix 7B15 Instruction Manual page 146

The voltages and waveforms shown were obtained with the controls set as follows :
TIME/DIV, 1 ms ; VARIABLE (CAL IN), knob in ; MAG X1 (button in), HOLD OFF, fully counterclockwise ; SWP CAL,
midranged ; POSITION, midranged ; TRIGGERING : LEVEL, midranged, MODE, AUTO ; COUPLING, AC ; SOURCE, EXT ; SLOPE,
+ ; EXT TRIG IN, IN (1 Mfg) ; B DELAY MODE, B STARTS AFTER DLY ; DELAY TIME, fully counterclockwise ; TIME, fully
clockwise ; TRACE SEP, fully counterclockwise .
Voltage Conditions . The voltages shown on the diagram were obtained using a digital multimeter with a 1 M 0 input
impedance (Tektronix DM 501 Digital Multimeter or Tektronix 7D13 Digital Multimeter used with readout equipped, series
oscilloscope) .
Waveform Conditions . The waveforms shown below were obtained using a test oscilloscope system with 1 Mfg input
impedance and at least 15 MHz bandwidth (Tektronix 7603 Oscilloscope, 7B53A Time Base, and 7A13 Differential
Comparator equipped with 10X probe) . A 4 volt, 1 kHz square wave signal was fed to the EXT TRIG IN connector .
