Battery-portable oscilloscopes offer up to five hours of field use

Saelig Company, Inc offers the Micsig STO1004 four-channel battery-powered portable oscilloscope, which provides 100MHz bandwidth, 70Mpts memory, 1GSa/s sampling (single channel), 130,000wfm/s refresh rate, and a 7.5Ah Li-battery for extended field use. Improvements over earlier Micsig models include an intelligent bidirectional Universal Probe Interface for housing and powering smart probes such as those with differential inputs and new joystick control buttons. A smartphone app is also offered for remote instrument control.

This innovative portable instrument combines a capacitive 8” TFT LCD touch screen (touch, drag, and swipe) with a conventional ‘button and knob’ operation. An external USB mouse can also be connected for further control choices. The built-in HDMI output adds educational, and demonstration possibilities for large displays or projectors, and an auto-calibration function provides measurement accuracy. The device has a highly sensitive digital trigger system and supports serial bus triggering and decoding. It has multiple measurement and math functions and comes standard with a digital filter module, 256-level intensity grading and colour temperature display functions. Sophisticated waveform triggering techniques include Edge, Pulse Width, Logic, Time Out, Video, Nth Edge, Runt, Slopetime, and Serial Decode. A screen capture button offers a quick way of saving waveform images for reviewing later or report writing.

The oscilloscope is able to make 31 types of automatic measurements, which can all be displayed on the screen simultaneously, and it can decode a selection of serial protocols, including UART, CAN, LIN, I2C, SPI, 1553B, and ARINC429. I/O provisions include WiFi, USB 3.0/2.0 Host, HDMI, USB Type-C, Trigger Out connections, DC Power input, and Aux out. 32GB of internal data storage is included for data files which can be transferred to a PC via a USB connection, LAN, or WiFi.

The oscilloscope includes a bumper-protected black case with a sturdy built-in prop stand for easy viewing. Live screen images can be transmitted to an external projector when the oscilloscope is connected to a LAN or WiFi network. The scope can also be remotely PC-controlled via WiFi, LAN, or USB and via an Android mobile device. Two x10 passive probes and an external 12V power adapter are included as standard.
