Total Phase: Buy in India
Authorized India Partner · GSAS Micro Systems
Total Phase × GSAS
Total Phase (Santa Clara, California, founded 2005) builds protocol analyzers and host adapters that decode bus-level transactions, the I2C register read, the USB descriptor enumeration, the SPI flash command sequence, the CAN message arbitration, giving embedded engineers visibility into what the bus is actually doing rather than inferring behavior from oscilloscope waveforms. Winner of the Embedded World North America "Best in Show" award, Total Phase instruments are trusted across USB device validation, automotive CAN bus debugging, production flash programming, and I2C/SPI sensor bring-up.
GSAS has been India's authorized Total Phase partner since 2015. Across six offices, Bengaluru, Chennai, Hyderabad, Delhi NCR, Mumbai, and Pune, we provide hands-on application engineering, demo units, instrument selection guidance, API integration support, automated test scripting, and production test fixture design.

Product Families
Total Phase Products by Category
Promira Serial Platform
Total Phase's flagship host adapter and protocol analyzer in one, a next-generation, field-upgradeable instrument that adds I2C, SPI, and eSPI capability as downloadable application licenses. As a host adapter it drives 80 MHz SPI (10x the Aardvark) and 3.4 MHz I2C High-Speed mode; as an analyzer it sniffs I2C up to 5 MHz, SPI up to 40 MHz, and eSPI up to 66 MHz. Built-in level shifting (0.9V to 3.45V, 5V tolerant) and Quad/Dual SPI lanes let one instrument replace a separate host adapter and bus analyzer.
Beagle USB Analyzers
Beagle USB 5000 v2
USB 3.0 SuperSpeed (5 Gbps) with simultaneous USB 2.0 capture. Hardware-level complex match-and-trigger, cross-channel analysis, and deep capture memory for intermittent failure hunting. The instrument for teams debugging SuperSpeed storage devices, USB 3.0 hubs, and high-bandwidth imaging.
Beagle USB 480
Non-intrusive USB 2.0 analysis (Low, Full, High Speed up to 480 Mbps). Real-time protocol decoding of setup packets, data phases, handshakes, and error conditions. Class-specific decoding (HID, MSC, CDC, Audio). The standard first instrument for Indian teams building USB peripherals and medical devices.
Beagle USB 480 Power
USB 2.0 analysis (up to 480 Mbps) with simultaneous bus-power monitoring, captures VBUS voltage and current (to 20V / 3A peak) alongside the protocol stream. Adds hardware complex match-and-trigger (8-state) and a 256 MB capture buffer. The instrument for USB power-delivery debugging and current-profiling devices through enumeration and suspend/resume.
Beagle USB 12
Non-intrusive USB Low- and Full-Speed (12 Mbps) analysis with real-time protocol decode and basic class decoding. The cost-effective entry analyzer for legacy USB 1.x peripherals, HID devices, USB-serial adapters, and embedded full-speed designs on a tight budget.
Beagle I2C/SPI Analyzer
The entry-point instrument for embedded serial bus debugging. Passively captures I2C traffic (up to 4 MHz) and SPI traffic (up to 24 MHz) with hardware timestamping and protocol-level decoding in the Data Center Software. For firmware engineers debugging sensor initialization, EEPROM read/write operations, SPI flash programming, or validating I2C device trees on new board bring-ups.
Host Adapters
Aardvark I2C/SPI
Industry workhorse for bus exercising and production flash programming. Actively drives I2C master/slave (800 kHz) and SPI master/slave (8 MHz). Programs EEPROMs, communicates with SPI flash, emulates sensors. API-first design for Python/C# test automation.
Cheetah SPI
Purpose-built for high-speed SPI-only applications. 50 MHz SPI clock for production flash programming and large firmware image transfers. Same API and Flash Center compatibility as the full host adapter family.

Komodo CAN Duo
Dual-channel CAN 2.0 analysis and active transmission for automotive and industrial embedded teams. Two independent CAN channels simultaneously monitor separate buses (e.g., powertrain CAN and body CAN), or configure one as passive analyzer while the other actively transmits test messages for ECU validation. API-driven CAN test sequences, transmit specific message IDs, validate response frames, and log arbitration outcomes. GSAS supports automotive ECU teams in **Pune** and **Chennai** with Komodo application engineering.
Advanced Cable Tester v2
Validates USB Type-C and legacy USB cables for electrical compliance, pin continuity, e-marker chip configuration, CC logic resistors, VBUS/GND resistance, and signal integrity parameters. Pairs naturally with Beagle USB analyzers: verify cable integrity first, then analyze protocol-level behavior to isolate whether issues originate in the cable or device firmware. Cable manufacturers and contract electronics manufacturers in **Bengaluru** and **Hyderabad** use it for incoming quality inspection.
