REQUIRES OPTION 233 (SPECTRUM ANALYSIS) AND OPTION 210 (VNA TRANSMISSION/REFLECTION) - SOLD SEPARATELY

***This option requires the usage of two FieldFox units***

ERTA can be used to measure the scalar transmission gain or loss of an RF system. It is useful when measuring long lossy cables where the two ends cannot easily be brought together, such as those bolted in on ships or aircrafts. It is also useful in measuring the insertion loss of waveguide systems or using the frequency-offset feature, devices such as mixers and converters.

ERTA measurements are based on two FieldFox units; one at each end of the measured DUT. One FieldFox is the source and reference receiver (R), while the other is the measurement receiver (B). The two FieldFox units are synchronized using hardware triggering. By taking advantage of FieldFox’s InstAlign technique, ERTA can be used to make accurate gain or loss measurements.
