Lecroy waverunner LT344 oscilloscope 500MHZ 500MS/s 4CH
Up for sale is a LeCroy LT344 Oscilloscope. This is a very high end 500mhz 500ms/s scope with 4 channels and an external triggering channel. The scope includes many great features that allow you to do complex measurements and tasks with ease.
Here are the specifics from the website:
Automatically sets timebase, trigger, and sensitivity to display a wide range of repetitive signals; vertical find automatically sets sensitivity for the selected input signal.
Triggers when signal meets slope and level condition.
Triggers on glitches down to 2 ns. Width selectable from <2.5 ns to 20 s or on intermittent faults.
Triggers on intervals selectable between 10 ns and 20 s.
Triggers on input only after a defined state or edge occurred on another channel. Delay between sources is selectable by time or events.
Triggers if the input signal drops out for longer than selected time between 25 ns and 20 s.
Triggers on logic combination of five inputs - CH1, CH2, CH3, CH4, and EXT trigger, where each source can be defined as High, Low, or Don't Care.
Triggers on line (up to 1500), NTSC, or nonstandard video, choice of fields**.
** 1, 2, 4, 8 fields for LT364/L; odd or even fields for all other models
16 Mbytes: LT364, LT344, LT342, LT322, LT224
32 Mbytes: LT364L, LT344L, LT342L
**Store full-length waveforms with 16 bits/data point.
For front panel and instrument status: Four non-volatile memories and floppy drive are standard. PC card hard drive and memory card are optional.
Simultaneously perform up to four math processing functions; traces can be chained together to perform math on math. standard math tools:
average (summed to 4000 sweepts)
enhanced resolution (to 11 bits vertical)
Automated Measurements: Display any five parameters together with their average, high, low, and standard deviations.
Test any five parameters against selectable thresholds. Limit testing is performed using masks created on the scope or PC. Setup a pass or fail condition to initiate actions such as hardcopy output, save waveform to memory, GPIB SRQ, or pulse out.
Extended Math and Measurements Option
Adds math and advanced measurements for general-purpose applications. Includes all standard math and measurement tools, plus:
delta time @ level; % and units
delta time @ level from trigger
delta time from clock to data + (setup time)
delta time from clock to data - (hold time)
Includes the Extended Math and Measure Tools as well as expanded capabilities for performing FFTs, averaging, histograms, and histogram parameters.
Histograms with 18 histogram parameters
Summed averaging to one million sweeps
FFT (up to 1 Mpoint waveforms)
FFT power density, real, and imaginary
Jitter and Timing Analysis (JTA), PowerMeasure System, Telecom Mask Testing
Remote Control: Full control via GPIB and RS-232-C (standard) or via Ethernet for all instrument controls and internal functions (optional).
Ethernet Port (Optional): 10 Base-T, TCP/IP Protocol
Floppy Drive: Internal, DOS-format, 3.5" high-density
PC Card Slot (Optional): Supports memory and hard drive cards.
External Monitor Port: 15-pin D-Type VGA-compatible, 640 x 480 RGB
Centronics Port: Parallel printer interface
Internal Graphics Printer (Optional): Provides hardcopy output in <10 seconds.
Calibrator Signal: 500 Hz 1 MHz square wave, -1.0 to +1.0, test point, and ground lug on front panel
Control Signals: Choice of trigger ready, trigger out, or pass/fail status; TTL levels into 1 MOhm at rear panel BNC (output resistance 300 Ohms 10%)
Operating Conditions: Temperature 5 40 C; humidity 80% non-condensing at 40 C; altitude <=2,000 meters
Shock and Vibration: Conforms to MIL-PRF-28800F, Class 4
Power Requirements: 90-132 V AC and 180-250 V AC; 45-66 Hz; maximum power dissipation: 150 VA - 230 VA, depending on model
Certifications: CE, UL and cUL
Dimensions (HWD): 210mm x 350mm x 300mm; 8.3" x 13.8" x 11.8" (height excludes feet)
This scope has an intermittent screen. Sometimes it works perfectly and sometimes it doesn't. There was a bad connector on the cable going to the screen, and it was repaired, however the screen produces an image about half of the time. I am not sure why. I am including a external LCD monitor that you can plug into the back of the unit to get external display of everything that would be on the main screen. It is the sae form factor, so it works great.
I have tested the scope myself and it works perfectly. The only reason I am selling it is because it is much more then I need in a scope and my Tek TDS224 works perfectly for my needs.
