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 CRY. 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 ConvenienceFour
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
measurementsto be made on highly asymmetric or jittering waveforms.
It provides accurate delayed and ¿time measurements--from the first
pulse on the trace-- and allows the operator to examine the A-trigger
event in detail.Input impedance is selectable between 1MO and
50O on Channels 1 and 2, eliminating the need for external 50O
terminators. Overload protection is also ensured. If excessive signal is
applied while 50O coupling is selected, coupling automatically switches
to 1MO coupling to prevent possible damage.EnvironmentalExceptional
electromagnetic compatibility qualities make the 2465/2445 family
oscilloscopes attractive for use in high-RF situations such as computer
manufacturing, testing, and servicing. These instruments are also UL
listed and CSA certified for safety. Their rugged design meets MIL-T -
28800C environmental requirements for Type III, Class 3, Style C
equipment.Precision MeasurementsThe 2465 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 andaccurate results of voltage, time, frequency, ratio, and phase measurements.Cursors
increase accuracy and operator productivity. With them, measurements
can be made quickly, with almost no chance of interpretation errors and
no CRT linearity error. The front panel controlled Channel 1 - Channel 2
delay-matching adjustment compensates probe and vertical-channel delay
differences.CRT ReadoutsReadouts permit easy setup and
interpretation of waveform displays. The horizontal time base always
remains calibrated with three significant digits and a decimal point,
even if variable settings are used.
