Switching block
Description
Switching block is provided for test and measurement of signals with frequencies GSM 900 and 6.6 GHz and also for switching the channels. X1 and X2 channels are provided for input signals with frequencies 6.6 GHz, and X3 and X4 channels are provided for input signals with frequencies 2.7 GHz.
Switching block is provided for the 220 V power supply voltage.
The switches in the switching block are managed by the ''Digital Control'' microcircuit in case of connecting to the connector RS232 (ComPort).
Signals with frequencies 6.6 GHz and GSM 900 are getting out to the output accordingly from the connectors CH 0A, CH 1A and CH 2A.
Switching block is doing measurements with the all parameters of signal with the channel COM A. The measurements are executed using measuring devices USB 5681 (Power Meter) and PXIe-5663E (6.6 GHz Analyzer) manufactured by National Instruments accordingly using connectors USB and X5.
Connectors LINK 1 and LINK 2, also GSM 1 and GSM 2 can be both input and output accordingly for 6.6 GHz and GSM 900 frequencies.
