| With a
storage writing speed of 5 div/ns, the LA354 is the fastest Analog Storage Oscilloscope
available today.
Analog oscilloscopes offer unique benefits in solving specific measurement
problems. The analog display provides important clues to relative frequency content of
signals mixed together or the occurrence of low rep-rate events on repetitive signals. The
LA354's scan- converter tube, combined with a TFT-color LCD screen, effectively displays
and stores these "grey scaling" and "persistence" effects with up to
5 div/ns writing speed, and its ultrafast display update rate lets you see how the
waveforms behave in real time.
The standard multipurpose trigger, wide- input offset range, 51/2-digit frequency
counter, and comprehensive cursors make the LA354 a truly universal storage oscilloscope.
 
DC - 500 MHz, 4-CH
Four channels up to 500 MHz are available, with CH1 and CH2 boasting the widest
frequency range with highest sensitivity (2 mV/div). The fastest sweep speed is 500
ps/div.
Ultra-High Writing Speed
With a visual writing speed of 5 div/ns and a display update of one million times per
second, the LA354 is the fastest analog storage oscilloscope available, thanks to its
unique scan converter tube technology.
Timebase Dual-Delay Function
Permits simultaneous "zoom" examination of two separate portions of a
waveform in real time.
Input Offset Function
Suitable for the observation of small signals superimposed on large signals. The DC input
offset function features an offset equivalent to ±500 div. max, which can be applied to
CH1 or CH2.
Counter Measurement Function
Built-in 5-digit counter for frequencies up to 500 MHz.
Save/Recall up to 256 Panel Settings
Just turn the FUNCTION knob to recall panel setups. Stores up to 256 settings in memory.
Power for FET Probe
Dedicated power supplies for two FET probes. Controls DC offset voltage of each probe as
well.
TV/HDTV Synchronization
TV triggering is available for NTSC, PAL (SECAM), and HDTV. Field (EVEN, ODD, BOTH) and
line select functions are included.
TV Clamp Function
Easy observation of TV video signals with fluctuating average voltage. Back porch level of
composite signals is fixed to ground level for display.
Typical Applications
- Video signals
- HDTV applications
- Data recording, finding servo anomalies, glitches and intermittent phenomena in
disk-drive head signals
- Pulsed laser related measurements
- Radar/Lidar burst measurements
- Eye pattern measurements
