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

Saelig Company, Inc offers the Micsig STO2000C Series Two-channel Portable Oscilloscopes, which provides a bandwidth choice of 200 or 300MHz, a huge 280Mpts of memory, fast 2GSa/s sampling rate (single channel), up to 270,000wfm/s refresh rate, and a 7.5Ah Li battery for extended field use.

This innovative portable instrument consolidates a capacitive 8” TFT LCD touch screen (touch, drag, and swipe) with traditional ‘button and knob’ operation to simplify and provide efficient scope operation. An external USB mouse can also be connected for extra control selections. The built-in HDMI output adds educational, and demonstration possibilities for large displays or projectors, and an auto-calibration function ensures measurement accuracy. The series adopts a high-sensitivity digital trigger system with abundant trigger and decoding types. I2C, SPI, RS232/UART, CAN, LIN and aerospace and defence (MIL-STD 1553, ARINC 429) with two formats to display decoding, text and graphics. Sophisticated waveform triggering techniques include Edge, Pulse Width, Logic, Video, Runt, Nth Edge, Time Out, Slopetime, and Serial Decode. A screen capture button provides a swift way of saving waveform images for later review or report writing.

The STO2202C (200MHz) and STO2302C (300MHz) oscilloscopes can take 31 types of automatic measurements, which can all be shown on the screen simultaneously. Bandwidth filters are offered to help focus on specific signals: 20MHz, high-pass, and low-pass. These scopes can decode several serial protocols, including UART, CAN, LIN, SPI, I2C, 1553B, and ARINC429. I/O provisions incorporates WiFi, USB 3.0/2.0 Host, USB Type-C, HDMI, DC Power input, Trigger Out connections, 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 offers a bumper-protected case with a sturdy built-in prop stand for simple 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 display or remotely controlled via WiFi, LAN, or USB, through a PC or an Android mobile device. Two x10 350MHz passive probes are included as standard with an external 12V power adapter.
