E440xBU Option H70 Performance Test
Measuring the Bandwidth of the IF Output
This test measures the ESA’s bandwidth at the 70 MHz output connector. A swept signal is
applied to the analyzer and the bandwidth is measured using another analyzer.
1. While the spectrum analyzer is still connected to the 70 MHz IF Output connector on
the rear of the ESA, configure the ESA and test equipment as follows:
