With three channels and up to 200 MHz bandwidth, the LA302 and LA303 analog oscilloscopes offer a high level of performance for relatively low cost.
Analog oscilloscopes offer unique benefits in solving specific measurement problems. The analog display provides important clues about the relative frequency content of signals mixed together or the occurrence of low rep-rate events on repetitive signals. The analog display effectively displays these "grey scaling" and "persistence" effects. The
ultra fast display update rate lets you see how the waveforms behave in real time.
The LA302 and LA303 are perfect instruments for service and educational applications. Equipped with extensive TV triggering, both scopes are excellent for video testing.
The standard multipurpose trigger, five-digit counter, and comprehensive cursors make the LA302 and LA303 truly universal oscilloscopes.
Features
Convenient
fine-adjustment mode
Pressing
FINE and turning the knob enables slow scrolling of
waveforms a function comparable to a digital
storage scope's roll mode.
Line
triggering provided for AC line measurement
AC
line-related measurement of various frequencies can
be obtained.
Third
channel input
CH3
provides three sensitivity levels for a wider range
of measurements.
Input
with probe sensor function
When
using a probe, the range display is automatically
calibrated by detecting 10:1 or 100:1 with the probe
sensor.
