As shown on waveforms
VoltsIDiv As shown on waveforms
Signal input: A one volt, one kilohertz sine-wave applied to both the 7B70 and 7871 EXT TRIG IN connector.
All voltages given on the diagrams are in volts. Voltages taken using
a
Fairchild Model 7050 non-loading digital multimeter.
Waveforms shown are actual waveform photographs taken with a Tektronix Oscilloscope Camera System and Projected
Graticule. Voltages and waveforms on the diagrams (shown in blue) are not absolute and may vary between instruments
because of differing component tolerances, internal calibration or front panel control settings. Readouts are simulated in
larger-than-normal type.
