The VT-RC-70 is a rugged, compact FM telemetry receiver covering the S, L and NATO bands. The small size allows it to be installed in or near the telemetry antenna removing signal cable loss and the requirement for signal amplification. USB interfaces make the VT-RC-70 easy to install and use. USB extenders are available to allow the positioning of the VT-RC-70 up to 500 meters from the controlling computer. Controlling the VT-RC-70 is simple with the provided PC based driver and any serial port command software. Optionally the VT-RC-70 has VuSoft support for a full graphical programming interface and integration into end-to-end telemetry systems.

Software Interface
The “iRig” Digital Receiver is the result of a multi-year research and development program that applies the latest digital technology to products for the flight test industry. “iRig” was designed from the ground up to offer substantial technical advantages over traditional telemetry products. Besides the improvements in RF reception performance, the iRig has the ability to bit-synchronize and derendomize the base-band and simultaneously send the received data to a host PC via USB for soft-decommutation and recording. This truly is an all-in-one, next generation telemetry system.
FEATURES:
• Multi-band Receiver
A single receiver that covers L, Upper L, S and NATO bands with exceptional performance for all demodulation types, FM (ARTM TIER0), AM, PM, SOQPSK (ARTM TIERI) and optionally Multi-H CPM (ARTM TIERII)
• Complete Receiver - RF to Time Tagged Decommutated Data
An integrated solution which accepts RF signals and delivers both base band clock and data with support for derandomization from 9 to 23 bits and time tagged decommutated data.
• Trellis Demodulation in all ARTM Modes
ARTM Tier 0, I and optionally Tier II with trellis detection in all modes.
• Minimum 3.5 dB Improvement in PCM/FM Performance
Improved BER performance through the use of a digital multi-symbol demodulator offering 3.5 dB better performance over the best single-symbol demodulators, resulting in reception to within 0.2 dB of the theoretical limit.
•Enhanced Synchronization
Synchronizes faster than traditional bit syncs, maintains sync at lower signal-to-noise ratios and offers much more accurate bit lock indication.
• Multiple Preset Memory Storage
The receiver offers eight memory setup registers which can be preprogrammed with receiver setups and selected in flight via a three line open collector interface, compatible with a simple rotary switch.
• Integrated Time
IRIG A, B and E time decoder, GPS time decoder with 1PPS and IRIG A, B and E time generator.
• Telemetry Encoder
The receiver has an integrated NRZ-L/M/S, BIO-L/M/S, RNRZ 9/11/13/15/17/19/21/23 telemetry encoder that offers speeds up to 40 Mbits/Second with all codes types.
• USB2.0 Interface
The receiver has a high speed USB 2.0 programming, monitoring, soft decommutation data recovery and encoder data interface with advanced Windows based control and monitoring software.
• Status Indicator Lines
The receiver offers an open collector status line that can be used to illuminate a cockpit indicator to confirm data reception.
• Speech Audio Status
The receiver contains a voice audio system that can be set to speak the receiver settings on changing a memory preset, to provide speech based reception status on open collector switch closure or generate user programmable tones based on reception status.
• Low Power Consumption
Nominal 28 Volts DC at 350mA.
