Freq Resp Below 300 kHz Performance Test

This test applies to the following models:

• EXA — N9010A/B/N
• MXA — N9020A/B
• MXA — N9021B
• PXA — N9030A/B
• UXA — N9040/41B

• NFA — N8973B/74B/75B/76B

Frequency response (aka. Flatness) is defined as the amplitude deviation from the reference amplitude at 50 MHz. The complete analyzer frequency response is measured with several tests.

The model and options of the DUT will determine which tests are run from the list below.

• Freq Resp 300 kHz to 3.6 GHz Preamp Off
• Freq Resp 300 kHz to 3.6 GHz Preamp On
• Freq Resp 300 kHz to 3.6 GHz AC Coupled
• Freq Resp 300 kHz to 3.6 GHz Option EA3
• Freq Resp 50 MHz to 3.6 GHz Preamp Off Input 2
• Freq Resp 50 MHz to 3.6 GHz Preamp On Input 2
• Freq Resp Above 3.6 GHz Preamp Off
• Freq Resp Above 3.6 GHz Preamp On
• Freq Resp Above 3.6 GHz Full Bypass Path
• Freq Resp 3.6 GHz to 50 GHz Preamp Off Input 2
• Freq Resp 3.6 GHz to 50 GHz Preamp On Input 2
• Freq Resp Unpreselected Preamp On
• Freq Resp Above 3.6 GHz Full Bypass Path
• Freq Resp 3.6 GHz to 50 GHz Full Bypass Input 2
• Freq Resp Below 300 kHz

Band 0 Frequency response is specified relative to 50 MHz. This test measures frequency response (flatness) over the frequency range from 50 Hz to 300 kHz, relative to the response at 300 kHz. This is converted to a frequency response relative to 50 MHz by adding the normalized (to 50 MHz) 300 kHz Frequency response from the 300 kHz to 3.6 GHz Frequency Response Test.
