Whenthe CH2 INV ( button is engaged, thewaveform from channel 2 is subtractedfrom the channel 1 waveform and the dif-ference is displayed as a single trace.ALT: Alternate sweep is selected regardless ofsweep time.CHOP: Chop sweep is selected regardless ofsweep time at approximately 250 kHz.(3 POWER, SCALE ILLUMFully counterclockwise rotation of this control (OFFposition) turns off oscilloscope.
