About this file
This is a specification document detailing minimum essential characteristics for a hand-carried Transient Electromagnetic (TEM) profiler instrument that must meet or exceed "Brand Name or Equal to sTEM10 OEM: TEM Company" standards. The required system must support dual-moment operation (low moment at 1 Amp minimum, high moment at 10 Amp minimum) and achieve subsurface investigation depths of 200-500 meters. The instrument must support at least three interchangeable transmitter loop configurations (20x20 m, 40x40 m, and 80x80 m) without proprietary restrictions, feature single or multichannel receiver capability with minimum 4 MHz sampling rate and 24-bit dynamic range, and include 1,024 gates minimum with microsecond-resolution gate timing. The system must incorporate an integrated computing platform with at least 8 GB RAM and 256 GB SSD storage compatible with Windows or Linux, support real-time inversion or in-field data preview, and include wireless control via iOS and Android mobile applications with integrated WiFi and GPS positioning.
The instrument must meet IP65 enclosure rating for dust and water resistance, operate across -20°C to +50°C temperature ranges, and maintain a compact form factor approximately 36 x 27 x 14 cm for field portability. Power requirements include field-replaceable lithium-ion batteries in a dual-battery configuration supporting full 10-Amp high-moment operation with AC charging capability. Compatible receive coil sizes must include R36 (36 m²) or R100 (100 m²) options with minimum 100-200 kHz bandwidth. The complete system including instrument, coils, batteries, and cables must be transportable by one to two personnel and packable for vehicle or airline transport, with a minimum one-year manufacturer's warranty covering electronics and firmware.
