Information
The 55-5711 is an Oscilloscope with a frequency bandwidth
of DC to 100 MHz that can display 8 traces on 4
channels.
The SS~5711 is useful in a wide range of applications for
not only production lines and maintenance and service
purposes but also for the research and development of a
variety of electronic devices. The features of the SS-5711 are as follows:
'In addition to display of 8 traces on 4 channels. the SS-5711 has an ADD function for measuring the sum of two signals
and CH 2 POLAR for measurement of the difference between
two signals.
• Both CH 1 and CH 2 have a high deflection factor of 1
mV Idiv (in the x5 MAG function). which permits accurate
measurement of voltages.
· The horizontal deflection system has sweep rates up to
2 nsec/div (in the xl0 MAG function Iso that even highspeed
phenomena can be measured with accuracy.
• The SS-5711 has delayed sweep. single sweep. AL T
sweep, and X-V operation functions, and a TV synchronizing
signal separator circuit so that television and other
composite video signal waveforms can be observed.
