KEYSIGHT's N9915A-209 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 aircraft. 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…KEYSIGHT's N9915A-209 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 aircraft. 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 FieldFoxes, 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 FieldFoxes are synchronized using hardware triggering. By taking advantage of FieldFox's InstAlign technique, ERTA can be used to make accurate gain or loss measurements.Pre-requisite options: 210 (VNA transmission / reflection) and 233 (spectrum analyzer)Recommended options: 235 (preamplifier) and 307 (GPS receiver)An ERTA measurement system requires two (2) FieldFoxes and various accessories. See the FieldFox configuration guide for detailed ordering information.*This factory-installed option is for quoting purposes only. Only available with the purchase of a new main unit.
