Frequency Response Below 300 kHz
Performance Test
NOTE: The test Frequency Response 300 kHz to 3 GHz must be performed before
performing this test.
Frequency Response (or flatness) is defined as the amplitude deviation from the reference
value at 50 MHz. The complete E444XA Frequency Response is measured with three
different tests;
● Frequency Response Below 300 kHz
● Frequency Response 300 kHz to 3 GHz
● Frequency Response Above 3 GHz
The Frequency Response Below 300 kHz test is used to verify flatness from 10 Hz to 300
kHz. The 300 kHz normalized error from the Frequency Response 300 kHz to 3 GHz test
is used as the reference point for the Frequency Response Below 300 kHz test.
The Frequency Response Above 3 GHz test verifies flatness from 3.0 GHz up to 50 GHz,
depending on your instrument frequency range.
This test measures the E444XA flatness over the frequency range from 10 Hz to 300 kHz,
