Notes Unit has nine 6DJ8 tubes (only unique numbers listed above). The sweep delay generator gives a variety of sweep delay features to the Model 175A oscilloscope and also provides for single sweep operation. Through use of this plug-in, time relationships on complex signals or pulse trains can be accurately measured. The basic operation of the 1781A involves generating a linear ramp which, in conjunction with a pick-off circuit, generates a trigger that can be used either to arm or to actually start the main sweep after a selected time interval.
Net weight (2.2 lb = 1 kg) 5.25 lb (5 lb 4 oz) / 2.384 kg
