First Developments

CJSC “Electronic technologies and metrological systems ZET” was created on the basis of the SKB of the State Enterprise “All-Russian Scientific Research Institute of Physicotechnical and Radio-Technical Measurements” (VNIIFTRI).

The first modular design of ADC analog-to-digital and digital-to-analog converter DACs for a personal computer consisted of:

the direct access controller on the ISA bus;
ADC boards (12 bits, 50 kHz);
8-channel multiplexer.
Amplifiers for hydrophones and accelerometers.

Matching devices for strain gages by bridge and half-bridge circuits.
