The HP Model 140B is a general purpose plug-in Oscilloscope.
The deflection amplifiers are of the plug-in type and the
Oscilloscope contains only the power supply, calibration,
and CRT circuits. The plug-in amplifiers operate directly
into the CRT, therefore the Oscilloscope characteristics
depend upon the plug-ins used. Presently available plug-ins
make possible high sensitivity, wide bandwidth, and single,
dual, or four trace measurements in combination with normal,
single, or delayed sweeps. Double-sized plug-ins are also
available for special applications such as time domain
reflectometry, swept frequency indication, and spectrum
analysis.
1-3. The Model 140B provides power for the plug-ins and
line-frequency square wave calibrating voltages of 10 volts
and 1 volt peak-to-peak which are available on the front
panel. The primary power switch and all CRT controls are on
the Model 140B front panel, and the terminals and switch for
Z-axis modulation are on the rear panel.
1-4. CATHODE-RAY TUBE.
1-5. The Model 140B has an internal graticule CRT that
eliminates parallax error when observing the display. The
CRT is equipped with a nonglare safety face plate.
