Key-Scope Description

Key-Scope oscilloscope features a backlit 1.5" color LCD and is battery powered. The 50g light-weight can be connected via USB to a PC (USB cable is included). An updated copy of the PC Application will be available for free download on our web sites. All control parameters are selectable on the unit via the joystick push button or using the Application when connected to a PC. The signals are refreshed on the unit's LCD and the PC Application simultaneously and continuously.


Key-Scope oscilloscope converts an analog signal with a 10bit resolution at 1MSa/s (bandwidth max. 100kHz). There are two more models in final development stage and are introduced here later next year, Key-Scope oscilloscope II & III. Both convert analog signals with an 8bit resolution at  50/250MSPS (bandwidth max. 5MHz/25MHz, list price US$99/149).


Timebases are selectable in the range of 5us/div to 10sec/div. A roll-mode becomes active when set slower than 100ms/div. A Data Logger mode samples signals each minute and records up to hours. The Data Logger timebase can be set in the range of 1min to 1h per sample. The input voltage can  be set 10mV/div to 5V/div, in six steps. firmware update mode keeps the unit flexible for future updates via the USB connection. The USB data protocol is published for individual access to the scope.




The input impedance is 1MΩ for all settings. There are various trigger options such as Pre/Post positioning within the entire memory depth, selectable trigger level, negative/positive trigger signal transition internally or externally (use supplied auxiliary/trigger cable with clip).

When the external trigger is not used, this auxiliary port can be switched serving as digital output. Then a square wave output signal can be selectable in the range of 10Hz to 200kHz. 


Also a bit string of 120 Bytes can be defined individually to be sequencely shifted out to this port. The signal output duty cycle is also selectable. The auxiliary port can be displayed in the grid synchronized to the acquisition timebase (serving as 2nd channel). There are several Acquisition modes, such as SINGLE/RUN, AUTO or NORMAL selectable.

The zero line is selectable as well. Also AC/DC input coupling is switchable. Automatic measurement for frequency or voltage is automatically calculated and displayed at all times.

The battery is re-chargeable within 50 min (%80 or up to 2h for 100%) while connected to the USB.

The battery capacity runs the unit upto 4 hours continuously.
