7B80 Features
The 7B80 Time-Base unit provides calibrated sweep rates from 5 seconds t o 10 nanoseconds and triggering t o 400 megahertz
for 7700-, 7800-, and 7900-series oscilloscopes. A X I 0 Magnifier increases each sweep rate by a factor of 10 and a VARI-
ABLE TIMEIDIV control provides continuously variable sweep rates between calibrated steps. Variable hold off and alpha-
numeric readout are provided. Also, when operating in the AUTO TRIGGERING MODE, a bright baseline trace i s displayed
in the absence of a trigger signal. The 7880 can be operated as an independent time base or as a delayed-sweep unit with a com-
panion delaying time-base unit.
