• Notes
• The Type 3B2 Time Base Unit is used to generate sweeps for the 560-series oscilloscopes. The sweeps may be initiated immediately by the trigger pulses or they may be delayed a selected time after the trigger pulses. The unit provides outputs for digital unit displays as well as the usual analog displays. The unit provides sweep rates from 2 microseconds per division to 1 second per division in 18 calibrated steps with an accuracy of plus or minus 3 percent. A six position delay-time switch and precision dial multiplier provide sweep delay from 5 microseconds to 10.5 seconds.
