The QC-1922 is a dual-channel oscilloscope with a 20MHz bandwidth and variable input sensitivity from 5mV/Division to 5V/Division. The sweep rate ranges from 0.2us/Division to 0.5s/Division and can be magnified to 10 X to enable a maximum sweep of 20nS/Division. The dual channel feature allows you to view two separate input signals and display them either individually, alternately, chopped or added together. The CRO has a number of trigger modes and will easily synchronise with TV sync pulses etc. It is housed in a pressed steel cabinet that incorporates a folding stand, carry handle, and handy mains cable storage on the rear feet. The control panel is uncluttered and neatly laid out and the 135mm screen has an integrated 10mm square graticule. Display area measure 8 x 10 divisions.
