11 / 13 page K-TS1 RADAR TESTSYSTEM Datasheet Using K-TS1 as Synthetic Target For testing Doppler transceivers, you need normally a moving object, that reflects the transceiver's carrier and thus produces a Doppler signal in the transceiver. The same test may be accomplished by using K-TS1 in a much more comfortable and reliable fashion as "synthetic target". This results in a programmable Doppler frequency at the target's IF output and a phase shift at I/Q outputs of +90° (corresponds to an approaching target). By operating the test-stand with a known target, you may calibrate your test-stand by using the IF output signal level of the UUT as a reference. You get even more information on the behaviour of the UUT by using the K-TS1 "Table Display" mode (see Fig. 8). Based on the "Target EIRP" value, a calculation of UUT overall receiver sensitivity may be performed. Using K-TS1 EEPROM Feature K-TS1 as Standalone System You may use K-TS1 without any host connection, if you have stored the desired operation mode in EEPROM. This feature is useful in "Synthetic Target" mode (t=1). To enter this mode permanently, enter the following commands: (Step 1:) [Enter] If necessary, terminate a previous cyclic display (Step 2:) [c] [0] [Enter] switch off the CW carrier, it may interfere with the UUT carrier Step 3: [t] [1] [Enter] This turns on the Doppler target simulator (and causes a doppler signal at the UUT} Step 4: [g] nnnn [Enter] Enter simulator frequency Step 5: [r] [Enter] K-TS1 answers with a short message From now, K-TS1 automatically works as synthetic target after each power on. You may alter this setting at any time and store a new configuration in EEPROM. You may also use a standalone K-TS1 in "Tuning Mode". See chapter Tuning Mode. Startup with Preset Parameters Frequency and CW carrier state may be set to the desired values and stored to EEPROM by function [r]. From now, K-TS1 starts up with the new setting stored in EEPROM. © RFbeam Microwave GmbH www.rfbeam.ch 2011-03-11 Page 11/13 |
