koolitus/väljaõpe Tallinnas. Pakkumised esitada 14.12.2010. Tarne käesoleva aasta 51. nädala jooksul
(20.-24.12.2010.)
Nõutavad Spetsifikatsioonid:
1. Radiocommunication Service Monitor
Minimum requirements for functionality
o Transmitter, receiver, and duplex measurements on mobile radios, base stations, and RF
modules
o Analog signaling
o Manual and automatic measurements
o Tracking generator
o Spectrum monitor
o Decoding of DTMF dual tones and VDEW direct dialing
o Centronics Interface for direct printer connection
o ATIS Coder/Decoder and CDCSS Decoder
o 300 Hz Lowpass Filter
Should allow fast frequency and deviation measurement of subaudio tones with simultaneous
audio modulation (fcutoff = 200 Hz, attenuation >50 dB for frequencies above 300 Hz)
o Duplex Modulation Meter
Should allow operation of RF frequency counter and modulation meter independent of RF
signal generator (two part measurements, also on frequency-converting modules); provide
tracking generator, cable fault finder, adjacent-channel power meter, harmonic measurements
