Review: LeCroy WaveAce 112 Digital Storage Oscilloscope

This two-channel, 100MHz Digital Storage Oscilloscope takes up to 500 million samples per second, has comprehensive USB connectivity and a wide range of features in a stylish, compact package

Review by Nicholas Vinen

LeCroy are best known for their high-end test equipment. With this series of oscilloscopes they now cater for the entry level Digital Storage Oscilloscope (DSO) market.

The size and layout of this unit is similar to other entry-level DSOs. One obvious difference is the styling, which makes a nice change from the typical beige and grey boxes. The scope comes with two 1-metre 1x/10x 100MHz probes and accessories, a USB cable, a power cable, a software CD and the Getting Started Manual.

The probe accessories included are a ground spring (which can replace the alligator clip lead for high frequency applications), extra colour coding rings, a compensation adjustment tool and several additional probe tips including some that suit DIP IC pins. These prevent accidental shorting to adjacent pins when taking measurements. There is also a BNC adaptor which allows the probes to be plugged directly into BNC sockets.

On the rear panel is a pass/fail output, a serial port and a USB socket for connecting the oscilloscope to a computer or printer. On the front panel, in addition to the screen and controls, is a second USB port for flash memory drives, two BNC connectors for the signal inputs, the external trigger BNC input and a calibration output.

User interface

The display is the now-typical full colour quarter-VGA 5.7” LCD. It is better than average. with excellent contrast and a fast update rate.

Most of the screen area is dedicated to waveform display, which is partially occluded by a menu when accessing extended functions.

Each menu item corresponds to one of five adjacent “soft” buttons. A single button press dismisses this menu at all times.

LeCroy haven’t skimped on the controls either – there are separate vertical adjustment knobs for each channel.

Some entry-level DSOs have a common set of knobs with buttons to select which channel is being adjusted. That saves money and reduces clutter but making adjustments becomes significantly more awkward as you can’t always remember which channel is currently selected.
