This compact, light weight model 6500 series oscilloscope has a frequency range of DC-60MHz, [DC-40MHz] or (DC-20MHz), and offers the following features: (1) Wide frequency range: Frequencies up to DC-60MHz, [DC-40MHz] or (DC-20MHz). (2) High sensitivity: 1mV/div (3) Large size CRT : Waveforms are easy to read, on the large 6-inch CRT with an internal graticule scale. (4) Scale: Waveforms are parallax-free with the CRT’s internal graticule scale (5) Alt Mag· The normal( · 1) and the · 10( · 5) magnified waveforms can be displayed simultaneously. (6) Alt Trig: Stabilized triggering is accomplished even with two unrelated signals. (7) TV synchronization: Stable TV signals are displayed using new circuitry.
