Selectable 1Meg ohm, or 50 ohm input impedance for accurate RF measurements. 150 MHz Bandwidth w/ dual time base 4 Independent channels Cursors and Readout 2 mV/div Vertical Sensitivity 1 nS/div Sweep Rate Advanced Trigger System Versatile Triggering These oscilloscopes can trigger on any one of the four channel. New auto-level circuitry gives you convenient hands-off triggering, even with changing trigger-signal amplitudes. With the position-independent triggering, trigger level remains constant whenever you reposition the display. And the trigger-level readout enables you to preset the amplitude for predictable triggering on both logic thresholds and transient event. Single-sequence triggering can capture a single event or multiple events by displaying a single sweep of each trace on the CRT. At the ends of the sequence, scale factors and other readout data are briefly displayed and graticule illumination flashes on momentarily, allowing waveform photography. Measurement Convenience: Four channels produce clear and complete views to simplify complex measurements. With the B sweep you can display any portion of the A sweep, including the A-sweep trigger event. Sweep-delay range is adjustable down to zero delay. This combination allows easy timing measurements to be made on highly asymmetric or jittering waveforms. It provides accurate delayed and ΔTime measurements--from the first pulse on the trace-- and allows the operator to examine the A-trigger event in detail. Precision Measurements The 2465/2445 Family oscilloscopes set new norms in measurement precision. With 1% horizontal system accuracy and 2% vertical deflection accuracy, they give you greater measurement confidence than ever before. On-screen vertical and horizontal cursors deliver immediate and accurate results of voltage, time, frequency, ratio, and phase measurements.
