SD-203T Digital Sampling Precision Converter
SD-303NF Digital Sampling Precision Converter
 

 

The Three-Channel Digital Sampling Converter SD-203T, SD-303NF are a part of Antenna Test Area and intended for measurement of parameters of broadband repeated signals in frequencies range up to 26 GHz with internal and external triggering.

Digital Sampling Converters can operate together with personal computer IBM Pentium so its versatile characteristics are provided by all intelligent means of up-to-date computer and threshold parameters of the PC conjugated analog devices.

In particular the registered waveform can be subjected to any processing and filtering in time and frequency domain.
