Mouse oscilloscope

Screenscope is a stand-alone 50 MHz real-time oscilloscope. No computer is required. Plug a monitor and mouse directly into the rear of the unit, switch on and it is ready in seconds.

There is a large colour display with a graphic user interface that is designed to have the look, feel and ease of use of a conventional instrument. Most controls are operated by a single mouse click or wheel scroll. But more naturally, users can just grab and move objects in the measurement area directly using the mouse. After release, the wheel can be used to further finetune the object’s position.

It has two 8-bit channels and a third 1-bit which also serves as calibration output. Attenuation ranges from 5 V to 20 mV/div, with large voltage offset capability.

Timebase ranges from 3.3 nS to 1 h/div. Low speed ranges 100 mS/div down, displayed in chart recorder style where points are drawn in real time on the screen. This mode can log up to 999 screen runs as a continuous file to USB memory.

It has FFT and maths functions as well as four local memories which have their own traces on screen. There are two sets of manual measurement markers with resolution down to 100 pS horizontal and >300 µV vertical for the highest ranges.

Auto measures include Vppk, Vmag, VRMS, Vav, period, frequency, duty cycle and pulse widths. RMS and average can also be set to be calculated between the manual markers.
