E440xBU Option H70 Performance Test
Test Procedure For the 70 MHz IF Out
Amplitude Response
This test measures the ESA's amplitude response as a function of frequency. The test
calculates the amplitude response relative to 50 MHz and the peak-to-peak response.
A signal is applied to the analyzer at several frequencies. At each frequency the signal
amplitude is adjusted to place the signal at approximately the same displayed amplitude.
A power meter measures the signal amplitude.
Follow the steps below to prepare for the amplitude verification of the 70 MHz IF Output
on the rear of the ESA.
1. [Preset] the E440xBU ESA and all the test equipment.
2. Run Align All Now on the ESA. Press: [System] > Alignments > Align All Now.
3. Initialize the test equipment parameters as follows.
4. Zero and calibrate the power sensor.
5. Connect the power sensor/power meter to the Type-N cable that is connected to the
Source. Use an N (f) to N (f) adapter between the power sensor and the cable.
6. Adjust the Source [Amplitude] for a power meter reading of –10 dBm.
